There are two sample collection methods that labs are using nowadays. Those methods are the blood and buccal swab methods. But which one should you choose in case of a paternity DNA test?
The outcomes of paternity DNA testing with swabs and blood samples are the same. Although there are minor changes in how the two methods function. Depending on your preference, each has its benefits and limitations. Neither is better than the other; it all relies on the laboratory’s capabilities. Let’s look at how these two approaches function.
How do DNA samples work?
People who provide DNA samples for paternity DNA testing follow standard processes at DNA testing labs. A DNA test sample from a blood sample is identical to DNA obtained from your buccal swabs. So the result from your blood sample will be as precise as the sample taken from your cheeks.
How buccal swab works?
A buccal swab is a method of collecting DNA from cells inside the person’s cheek. It is a non-invasive method of collecting DNA samples for analysis. Buccal refers to the cheek or mouth. A buccal swab looks like a big cotton tip. By massaging the inside of the cheeks, it is possible to harvest cheek cells. It is as precise as a blood DNA test.
How does a blood sample work?
Blood is the most dependable source of DNA. The doctor uses a tiny lancet to puncture a finger during the process. Then they transfer a little drop of blood to a collecting card, and that’s all there is to it. There is no cost difference between buccal swab testing and blood testing.
Conclusion
Since DNA is the same across all nucleated cells in an individual’s body, DNA test findings will be the same. Although a blood sample usually yields a high amount of DNA, it comes with some complexity. Blood samples increase the costs and complexity of sample collection, shipping, and storage. Both buccal swabs and blood samples yield the same level of precision. But, because buccal swabs are simple and painless to get, many paternity DNA testing uses them.
