Buccal swabs, which involve collecting DNA samples from an individual's saliva by swabbing the mouth, emerged as an alternative to drawing blood for DNA testing. Buccal swabs non-invasive approach is just one advantage this method has in comparison to others.
Buccal swab DNA collection doesn't require the presence of qualified medical practitioners because of its simple process. The risk of infection from other ailments is less than blood testing. It is a painless procedure that doesn't require skin punctures, making it appropriate for children, babies, and adults who don't like their blood to be drawn.
Transporting DNA samples is less troublesome with buccal swabs, as there is no danger of leakage and they can be moved about on a card-like device. This ease of movement also makes the samples easier to store as refrigeration facilities are not required, unlike those acquired by a blood draw. They can stay for extended periods despite temperature fluctuations. Analysis of swab-collected DNA is also faster with automation and a more cost effective option than blood testing.
