A Local DNA Collection Facility explains Use of DNA Testing for Infidelity Cases
OK - so you have found a sheet, a pair of underwear, a blanket, a condom or some other item in a place that it should not be found. You suspect your partner of cheating but finding this article really doesn't prove anything. What can you do?
First, you must figure out how important it is to you to know the truth. Will it give you peace of mind to confirm that the semen and/or biological fluid on that sheet does not belong to you. What is the next step in your life if you do prove that your partner has been unfaithful? Doing the research and making your point can distract you from the consequences of Infidelity tests results. These are life changing events, especially if children are involved. So only if you are absolutely positive you know what you will do with results of these tests, should you go forward.
The very first thing to be aware of - do not store articles to be tested for biological fluids in a plastic bag or container. A plastic bag creates a humid environment which assist in deterioration of DNA and other biological fluids. Any item you want to be tested for biological fluid should be stored in a paper bag, envelope or other suitable container.
Semen Detection Tests - these are cheap, easily obtainable via the internet and if you only want to determine that Semen is found on an article then by all means, use the internet for your research. However, after determining that Semen is, or is not, present on the article - what does that prove? Is it your semen? A simple semen detection test will not tell you whose Semen is on the article only that Semen is present. A simple semen detection test will also not advise if there is a presence of female fluid. What if the Semen detection kit you bought over the internet does not pick up the presence of Semen but you still have a question about why or how the article was found where you found it or why there appears to be some biological fluid present? The internet Semen Detection Kits will only test for male biological fluids, specifically the prostate specific protein found in semen.
A professional DNA Infidelity Detection Services company has a standard set of tests to assist you with true infidelity questions. Your local DNA collection expert can guide you through a step by step process, based on your unique circumstances, to best identify what tests to take to identify the questionable articles and fluids. When you receive our results, using the tests we recommend, you will have clear and definitive answers to your questions. That is why we first emphasize the importance of really knowing what you want to achieve by taking these tests.
Our first recommendation in Infidelity Testing is to detect for the presence of specific biological evidence, either male or female, dependent on your situation. There are two main types of detection services, with two additional back up tests, that are used to confirm the presence of DNA and the presence of Semen.
DNA Detection - Y-Chromosome - this test is most commonly used when a man suspects a woman of cheating with another unrelated man. The test detects the presence of the male Y-chromosome and subsequently a genetic profile of the Y-Chromosome is typed if it is present. Only men carry the Y-Chromosome so only if a male's biologic fluid is present on an article will a genetic profile be created..
If the male client suspects that an immediate male family member, ie, brother, uncle, father from his side of the family may have contributed to the sample, a DNA Detection - Standard test must be used instead since there is a possibility of similar Y-Chromosome profile present on the article or in the fluid.
Note: The Y-chromosome is passed down from father to all of his sons through generations with very little mutation.
DNA Detection - Standard
This test detects the presence of both male and/or female cells. The results report will state if male, female, mixed profile of both sexes or multiple profiles of the same sex are found. If you are submitting a DNA sample of yourself for comparison purposes, and if multiple genetic profiles of different sexes are found in this DNA Detection Standard test, then a Differential Extraction Study will be necessary prior to proceeding with the DNA Comparison.
DNA Differential Extraction
A differential extraction test is used to separate male and female cells in a mixture of biological evidence. This test must be used if the initial sample results shows the presence of male and female profiles.
This test is used to compare a standard DNA sample (usually an oral swab) of the client, to a submitted article that has been processed through one of the above mentioned DNA Detection Services methods to a generate a genetic profile. A report will indicate a match or non match to the items submitted for detection.
The most important thing to consider is what are you going to do with the results. Call us for a confidential screening 732-632-8830 on what type of tests to consider, the costs involved and the turn-around time for results. Since the samples submitted to us are not collected under a New Jersey's strict chain of custody laws, the results of these tests may not be defensible in a court of law.
