As the cost of DNA testing has come down, many people opt for a variety of DNA tests of which paternity test is one. Paternity DNA testing can be carried through a legal order to determine who is the baby’s father or mother, or it can be used for legal inheritance purposes. There are a few things you should be aware of concerning home paternity tests.
1. Home Paternity Test is affordable
Home DNA test kits are popular costing about $30 at the most. An extra amount for the report around $300 in non-legal DNA paternity test and more for a DNA paternity test through a court order can be charged. It should be kept in mind that if you go in for voluntary home DNA paternity test using a dna kit, it may not be accepted as evidence in court in the event of a dispute.
2. It is precisely accurate
DNA test is the most accurate way to determine the biological relationship whereas, blood tests and other methods are not infallible. For most accurate results one must have the test carried out by an ISO 17025 certified laboratory.
3. Results are more accurate if the mother is also tested
Usual tests match DNA of father with that of the child but if the mother is also included in the testing then the results are more accurate. Gene mutation can upset test results so including mother DNA test in the paternity test is a good idea.
4. Home paternity tests test only a few markers
Dr. Sanjay Gupta says in his article that various labs go about tests in different ways and may use only around 15 markers.
The human genome has three billion base pairs and to sequence the entire genome, it would cost tens of thousands of dollars. Whereas, home DNA test capture only a half million to one million spots and compare. Still, it is accurate. Kits look for single nucleotide polymorphisms.
5. Kit accuracy can vary and labs may misplace samples
The kit’s accuracy varies based on testing methods. It is not unusual for a dog’s DNA to be mistaken for a human DNA sample until pointed out. Workers at the lab could wrongly label your sample or send you someone else’s report.
6. You can now get court admissible home paternity test kits
You can get court admissible home paternity test kit for $ 230. In the normal course of things, if the matter goes to court then the court orders a DNA test in which an appointed officer collects the DNA samples in person. However, the court admissible home paternity kit can be used to produce report that will be accepted in court.
DNA test labs are increasing in number and DNA kits are coming down in price. This may be good news but you must also know that not all labs conduct tests the same way so, if much is at stake in a paternity test, it is best to select a certified and reliable DNA test laboratory for paternity tests.
