For DNA testing, any specimen can be used for DNA extraction like blood, buccal swab, routed hair, nails, semen stains, blood stains, skin and bones etc. but we prefer to collect blood or buccal swab sample for quality and accurate DNA test reports.
A buccal swab is a way to collect DNA from the cells of a person’s inner cheek i.e. inside mouth. Buccal swabs are a relatively non-invasive way to collect DNA samples for testing. Buccal means cheek or mouth. A buccal swab resembles a large cotton tip. It is used to collect cheek cells by rubbing the inside of the cheeks. It is as accurate as blood DNA test.
Blood is considered as most reliable sources of DNA. The procedure involves a small lancet that is used to lightly pierce a finger. A small drop of blood is then transferred to a collection card – that’s it. In terms of cost there is no difference either you choose buccal (cheek) swab testing or blood testing.
STRs is an acronym for Short Tandem Repeat. These are genetic elements (sequences in the DNA) that are used in forensic DNA analysis. There are other genetic elements that can be used for determining identity, but STRs are considered the most accurate and reliable method.
Actually no, there is no genetic, health or disease susceptibility information in DNA analysis using STRs. It only provides a STR profile that can be used, in conjunction with a database, to positively identify an individual.
We will collect your DNA sample after verifying the parties. You need to fill paternity requisition form and submit one of your government valid ID and legal guardian’s proofs of the child to the sample collector. We would also need a duly signed affidavit permitting us to perform the DNA fingerprinting test.
