Infidelity Test Questions You May Have

Which Infidelity test do I need?

The Semen Detection, Saliva Detection, and Blood Detection Infidelity tests are positive/negative tests.  They will tell you if the substance is present on your sample.  And, this may be all you need to know to answer your questions.  However, if you are a man wanting to know if the semen is yours, or a woman wanting to know a stain contains another woman's DNA, you'll need to do a DNA Comparison test and submit a sample of your DNA as a cheek swab.

If you only want to know if male, female, or a mixture of DNA is present on your sample–you want the DNA Detection Test.

If you want to wait and get the semen detection test results first, then decide if you want or need one of the DNA infidelity tests, that's OK.  All the infidelity test samples are kept for 60 days after the results are issued, so you have time to decide if you want further testing, or if you have all the answers you need.  If you decide you want one of the DNA infidelity tests after you get your results, you will be given a discount code for $25 off any DNA Detection or DNA Comparison test--just contact us and we'll walk you through the process.

If you are still not sure which one of the infidelity tests you need, call us at 915-407-6224 or send us a  and we'll assist you in selecting the appropriate test for you needs.

If you think there is a chance you have left your DNA on the sample by handling the area to be tested with your bare hands, we recommend you order the DNA Comparison Test and send a cheek swab from yourself.  This will eliminate you as a contributor to any DNA that may be found.


Do I need Autosomal or Y-str DNA Testing?

What is Autosomal and Y-str DNA?  Which do I need?

Autosomal DNA is the DNA from the 22 pairs of autosomal chromosomes. Autosomal DNA is inherited from both parents. Therefore, an autosomal DNA test may be taken by either a male or a female.

Y-str DNA is taken from the Y-chromosome. The Y chromosome is only found in males, which are only passed down by the father, making the Y chromosome in any paternal line practically identical.

Which do you need?

If you are only interested in determining if male DNA is present and if it's a match to your sample the Y-str test is preferable UNLESS you suspect the DNA present may have come from a direct male relative.  This test is able to detect male DNA in cases where an Autosomal test will not, but cannot distinguish between a father, son, brother, uncle, etc.

If you suspect a direct male relative, or are looking for multiple female DNA profiles, the Autosomal test is preferable.  This test will detect both male and female, but isn't as good at detecting small amounts of male DNA.

If you aren't sure, please reach out to us at info@privatelabresults.com or call 915-407-6224.


What can I send to be tested for proof of infidelity?

We can test almost anything for signs of infidelity: clothing – sheets – towels – sanitary pads – tampons – tissues – sex toys – condoms.  If you have something you want tested with one of our DNA infidelity tests but aren't sure about sending it check out the list below, or call us at 719-686-6980.  Have you found a stain on furniture, a car seat, or an item that would be missed?  If you have a suspicious stain you would like tested but can't send the item, you can send a swab of the area instead.  The instructions are here.

If you want to send an item for Infidelity DNA testing please note:

Items with a 90% or higher success rate of obtaining DNA:  Fresh semen on swab or fabric (if no vasectomy), mucus/sputum on tissue, napkin, etc, toothbrush

Items with a 60-90% success rate:  blood stain on fabric, tissue, gauze, etc., saliva stain, fingernail clippings (5-10 clippings), diabetic test strips (multiple strips recommended), ear swabs, cigarette butts (multiple preferred), tampon/feminine pad, drinking straw, dental floss

Items with 60% or less success rate:  hair (roots must be visible, 7-10 hairs needed), razor, comb/brush, chewing tobacco (less than three days old), jewelry, chewing gum (sugarless preferred), soda can/drinking glass, clothing (hats, bandannas, clothing worn next to skin) envelope flaps/stamps, condom


Will a vasectomy affect the test?

A vasectomy will not affect the ability to perform a semen detection test.  Our test looks for a protein that is present whether or not a man has had a vasectomy.  It can, however, affect the DNA infidelity tests.   DNA is present in highest concentrations in the sperm cells, so an absence of sperm can mean that no DNA will be detected.  DNA can also be found in skin, blood, or tissue cells that might be in the semen.  So while detecting DNA in semen from a vasectomized male is unlikely, it's not impossible.

How do I get started?

You can pay for the infidelity testing you need through the website by adding the test to your cart and checking out with your credit card. Once complete, you will receive a confirmation email with your order number.  Enter the order number on your Infidelity Sample Submission Form.  The charges will appear on your bank statement with our name and phone  number.  Once we get your sample, we'll send you an email to let you know it's arrived and testing has begun.  When your results are ready, we will send them to you in the manner you've indicated on the Infidelity Sample Submission Form.

If you do not want to use a credit card, you can send in a check or money order with your samples when you mail them to us. Make them payable to PLR or Private Lab Results.  When we receive your package, you will receive a confirmation email with your order number.

All our tests are done by trained technicians in an AABB, A2LA and CLIA certified lab. These are not home test kits.  We do not send anything to your home.

Please review our instructions for marking, packaging, and mailing in your sample.

For all the tests, print the Infidelity Sample Submission Form, fill it out and send it back in your package.  We will not begin testing without the signed form.

Mail everything to Private Lab Results, 8900 Viscount Blvd,  AN 142, El Paso Texas 79925.


How old can a sample be?

A woman can discharge fluids from sexual activity for 5-7 days. How long you can detect any semen in the discharge depends on how the item has been stored. For semen detection testing, as long as the item hasn’t been laundered and the stain is still visible it can be testable for years.

DNA can also last for years as long as the item has been kept dry, and stored in a cool, dark place away from heat and direct sunlight.  Never store samples for infidelity tests in a plastic bag.  Plastic traps heat and moisture which can degrade the DNA making it more difficult to get a complete DNA profile.

Can I get my sample back?

Sure.  Just add the sample return to your order at checkout.  You only need to add it once no matter how many samples you have.  If you want to wait and get your test results first, that's OK.  All samples for infidelity tests are kept for 60 days after the results are issued if you don't add the return to your initial order.  You can decide you want the sample returned or if you want further DNA or other testing at any time during that period.  Just contact us and we'll help you arrange it.  All returns are processed on the 1st and 15th of the month.

Can My Results Be Used in Court?

Chain of custody refers to the paperwork trail documenting the way a sample is collected and handled throughout the entire infidelity testing process. Since you will be collecting the samples yourself and submitting them privately, you will not have a strict chain of custody and the test results you receive will be noted as "informational only". Strictly speaking, for results to have a strict chain of custody, the samples must be collected by an unrelated third party such as a hospital, clinic, ME’s office, funeral director, law enforcement, etc. For obvious reasons this rigorous identification and handling procedure is not always going to be possible with infidelity testing.  Courts and legal official know this, and the weight an agency will give the results is up to the agency.

Cremated Remains Test Questions You May Have

What are cremains / cremated remains?

Cremains are the remains of a body that has been cremated. Technically, the remains are not ashes, they are bone. Once a body is cremated the bones are crushed to a fine, sand like powder. Depending on the equipment used, the remains may be fine like sand, or coarse with visible bone fragments.  Remains have also included surgical implants, wires, pins, and dental prosthetics.  Metal fragments from clothing worn during cremation may also be found.

How do I order?

Contact Us or call 915-407-6224.  We’ll send you an invoice you can pay online.  Once we receive payment notification, we’ll send you an email with shipping instructions along with chain of custody and return forms. You will ship the remains directly to the testing lab.  Testing takes 10 business days.

How long does testing take?

Results are normally ready in 10 business days.  A report of the findings is emailed or mailed to you.

How much should cremated remains weigh?

Generally, the weight of the remains depends on the height and sex of the person. How much a person weighed when they passed doesn’t have much bearing on the amount of remains you should expect to receive. A person’s height and bone density will determine the weight of the remains. A female’s remains are usually between 3-5 pounds and a male is usually between 5-7 pounds.

Do you need all the remains?

DNA testing requires that bone fragments or teeth be in the remains.  It's best to send them all so the best ones can be selected for testing.  Everything is returned to you after testing is complete. For the heavy metal  tests we only need 15g or about 1 tablespoon.  If any of the remains are left after testing they will be returned to you.

How do I ship the remains?

Once we receive payment notification we'll send you shipping information.  The USPS is the only carrier who will knowingly carry human remains.  Here's a link to their packaging and shipping instructions.  You will ship the remains directly to the testing facility.

What can you test for?

We can test cremated remains for heavy metals or to see if any DNA remains.  Drugs or prescription medications do not survive the cremation process.

Can you test for poisons?

Only if they are heavy metal based like arsenic, mercury, lead, etc.  Prescription medications or drugs do not survive cremation.

Can I use DNA results for ancestry or family history?

No.  If DNA is found in the cremains, the information is not the type needed for family history or genetic testing.


Who should test for metals?

Did your loved one work in the manufacturing, airline, plating, or metal or chemical production industry?  Were they farmers?  Unfortunately, jobs in these industries can expose a person to excessive amounts of toxic heavy metals. Was the deceased in the military, married to military, or a civilian that worked on a military base? If so, they may have been around dangerous levels of metals. Did they have metal implants, like a hip or knee replacement? Studies show that these devices can cause toxic poisoning. Do you have reason to believe that the person was deliberately poisoned?  Drugs or medications do not survive the cremation process, but if they were given arsenic, mercury, or another heavy metal based poison, we can test for evidence. 

Can you test for a single metal?

Absolutely.  Just give us a call to see if it's a substance we can test for.  Testing for a single metal is $250.

What are signs of arsenic poisoning?

Arsenic poisoning occurs after the ingestion or inhalation of arsenic. Arsenic is a type of carcinogen that’s gray, silver, or white in color. Arsenic is extremely poisonous to humans. What makes arsenic especially dangerous is that it doesn’t have a taste or odor, so you can be exposed to it without knowing it. While arsenic is naturally occurring, it also comes in inorganic (or “man-made”) formulas. These are used in agriculture, mining, and manufacturing.

Contaminated groundwater is the most common cause of arsenic poisoning. Arsenic is already present in the earth and can seep into groundwater. Also, groundwater can contain runoff from industrial plants. Drinking arsenic-laden water over a long period of time can lead to poisoning. Other possible causes of arsenic poisoning can include breathing air that contains arsenic, breathing contaminated air from plants or mines that use arsenic, living near industrialized areas, being exposed to landfill or waste sites,breathing in smoke or dust from wood or waste that was previously treated with arsenic, and eating arsenic-contaminated food.

Since arsenic is rapidly cleared from the blood, blood arsenic levels may not be very useful in diagnosis. If acute arsenic poisoning is suspected an x- ray may reveal the substance in the abdomen. Arsenic may also be detected in the hair, bones, and nails for months following ingestion. Within twenty four hours of ingestion arsenic moves from the blood directly into the victim’s kidneys, liver, lungs, spleen & the gastrointestinal tract. In 2 to 4 weeks traces can be found in the victim’s skin, nails, and hair. From there, traces of the poison settle in the bones. Within 35 minutes after ingesting arsenic the victim will experience garlic smelling breath, muscle cramping, metallic taste, headaches, vomiting, vertigo, diarrhea and abdominal pain. If the victim doesn’t die within the first few hours from shock, the poisoned victim will most likely die several days later from kidney failure. If the victim survives 2 to 4 weeks they will experience horrible suffering and will start losing their hair. When death finally comes it will most likely be diagnosed as renal failure.

What are signs of cadmium poisoning?

Cadmium is a highly toxic metal found in industrial workplaces. Due to its low exposure limit, over exposures may occur even in situations where very small quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not always lead to overexposure. Cadmium is also found in industrial paints and can present a hazard when sprayed. Operations involving removal of cadmium paints by blasting or scraping can pose a significant hazard. Cadmium is also present in the production of batteries. Exposure to cadmium can be found in the following industries: construction industry, shipyard employment, and the agricultural industry. Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms (chills, fever, and muscle pain) and can damage the lungs. Symptoms of inflammation may start hours after the exposure and include cough, dryness and irritation of the nose and throat, headache, dizziness, weakness, fever, chills, and chest pain. Inhaling cadmium-laden dust quickly leads to respiratory tract and kidney problems which can be fatal (often from renal failure). Chronic exposure (low level over an extended period of time) can result in kidney, bone and lung disease.

What are signs of chromium poisoning?

Chromium compounds are added to steel to increase corrosion resistance, hardenability, and are used in paints and dyes and the tanning of leather. Chromium compounds are often found in groundwater and soil at abandoned industrial complexes that are now in need of environmental cleanup. Chromium has also been used to produce paint primer and is still widely used for automobile refinishing applications. Chromium is known to cause cancer and targets the kidneys, skin, eyes, and especially the respiratory system.

What are signs of lead poisoning?

Lead poisoning occurs when lead builds up in the body, often over a period of months or years. Even modest amounts of lead can cause severe health problems. Children less than the age of 6 are more vulnerable to lead poisoning, which can profoundly affect physical and mental development. At higher levels, lead poisoning often causes death. Lead contaminated dust and lead-based paint in homes or buildings built before 1978  are the most common source of poisoning in children. According to the CDC, 24 million homes in the US still contain lead paint.  Lead piping and plumbing are also a significant source of lead contamination. Individuals who work in auto repair shops, do home renovations, make ammunition, or work with batteries may also be exposed to lead. Initially, lead poisoning can be hard to detect — even people who seem healthy can have high blood levels of lead. Signs and symptoms usually don't appear until dangerous amounts have accumulated. Although children are primarily at risk, lead poisoning is also dangerous for adults. Signs and symptoms in adults might include high blood pressure, joint and muscle pain, difficulties with memory or concentration, headache, abdominal pain, mood disorders, reduced sperm count and abnormal sperm, and miscarriage, stillbirth or premature birth in pregnant women.



What are signs of mercury poisoning?

Symptoms of mercury poisoning can be numerous and may occur either rapidly or over long periods of time. In general, symptoms occur and progress more rapidly the higher the dose of mercury encountered. Exposure to the various forms of mercury can result in some similar and some different symptoms. Symptoms can be grouped into three categories based on the form of mercury toxicity: 1) elemental and vaporized mercury, 2) organic mercury, and 3) inorganic mercury. Elemental mercury toxicity (which usually occurs in the vaporized form) can cause mood swings, nervousness, irritability, and other emotional changes, headache, muscle twitching and tremors. Organic mercury toxicity (most frequently in the methylmercury form from ingestion), causes neurological malfunctions, and especially in a fetus, impaired neurological development. Other symptoms include vision impairment, loss of coordination, needle-like sensations in hands, feet, and/or mouth, muscle weakness and impairments of speech and hearing. Inorganic mercury toxicity often causes skin rashes and inflammation (dermatitis). If ingested, it can dissolve tissues and some may be absorbed by the intestinal tissue. Large amounts of ingested inorganic mercury may cause bloody diarrhea. Absorbed mercury can spread to other organ systems resulting in mental changes including mood swings and memory loss or renal damage. Muscle weakness may also occur.
