Paternity Test

What is DNA paternity testing?

A DNA paternity test compares a child DNA pattern with that of the alleged father to prove or disprove their relationship with each other. We apply Polymerase Chain亲子鉴定 Reaction (PCR) V based analysis of Short Tandem Repeats (STR) of DNA fragments. By comparing the sizes of different STR loci, a unique genetic profile is produced for each tested individual. The childs profile is compared with the profile of the mother and alleged father to confirm that he or she has inherited DNA from the alleged father. We then perform statistical analysis to calculate the Paternity Index, which determines the probability of paternity. We routinely analyze 16 STR loci, which include, and exceed the 13 loci used by the FBI.

What about confidentiality?
Information of any kind regarding a case will not be released to anyone other than the tested parties and their named representatives without written order.
How accurate is DNA paternity testing?
HEAL guarantees at least 99.99% probability of paternity for inclusion (the alleged father is considered the biological father), and 100% certainty of exclusion (the alleged father is not the biological father).
What is the difference between the legal and the private test?
There is no difference in terms of accuracy and testing technique between the legal (chain-of-custody) test and the private test. The only difference is that with the legal test, you will need a neutral third party to witness the sample collection, and you have to provide government-issued IDs for all tested parties. Chain-of-custody paternity testing results can be used in a court-of-law while private testing results are not accepted by courts or other government agencies.
