DNA Paternity Testing Procedures: Buccal Swab Test Versus DNA Hair Testing

DNA testing has many applications across a broad array of disciplines and industries. DNA profiling is used to establish the identity of individuals largely for forensic purposes and for use in law enforcement services. Personal identification and kinship analysis as well as family relatedness are also popular forms of DNA analysis.
A recent study determined that 1 in 10 Americans ponder questions related to paternity. Establishing a biological relationship between parent and child is significant. Whether for financial support, immigration requirements, emotional reasons, health care tracking, peace-of-mind or even legal situations paternity testing can provide the needed answers.
There are several types of DNA paternity testing procedures:
DNA Blood Test
Paternity testing procedures have historically been conducted in hospitals and laboratories under prior authorization and using a blood draw for specimen.
Today, home paternity testing kits are available at local drug stores across the country. These kits can be used for peace-of-mind and for legal (court-admissible) reasons-using the same laboratory process as hospitals do with blood.
Buccal Swab Test
The method for collecting DNA samples for paternity is through a buccal swab test (also referred to as a DNA mouth swab test or a DNA cheek swab test). Using buccal swabs is just as reliable as using blood but far more convenient.
There are also many other advantages. The use of buccal swabs is non-invasive, and a much easier technique for the collection of DNA samples. Buccal swabs don’t require refrigeration like blood samples do, and they are good for several months after the collection has taken place.
DNA Hair Testing
Special specimens are sometimes used in place of a cheek swab sample. For example, a situation may exist in which the alleged father is deceased or otherwise not available to participate in the paternity testing. Special specimens are considered anything other than a buccal swab test used to extract DNA. Examples of this can be hair follicles (with root attached), toothbrush, q-tips, or tissue samples of any kind.
There are many challenges to DNA hair testing. First, the root of the hair follicle must be attached. DNA is not found within the hair shaft. Secondly, it cannot be guaranteed that a sufficient sample with good quality can be extracted. In a paternity test this could cause an inconclusive result. Thirdly, testing hair is an expensive process. Additional extraction techniques are performed for special specimen and often numerous attempts are made in an attempt to obtain DNA. The extraction cost is separate from the actual laboratory cost in this situation and can be quite an expensive alternative.
Though there are many DNA paternity testing procedures using buccal swabs is a much easier process as opposed to other sample types including hair. Be in the know, purchase a home paternity testing kit today.
