Buccal Method -
"Cheek Swab" Test

To gather a DNA sample for testing, the buccal method, also known as the cheek swabbing method, is often the preferable option for those who have very young children. Simply use the provided swab that comes with the dna test kit to swab the inside of your child's cheek. And just like that, you've got the DNA sample you need.

INOL offers quick, easy, and affordable DNA testing services.  DNA testing services from INOL involve several simple steps that include DNA sample gathering through cheek swabbing or blood sampling from the child and the alleged father, DNA sample submission, and comparative DNA analysis in our lab. When you do dna testing with INOL, most analysis results are available within three business days. We have a five-day results guarantee.
