A Sequential medical professional will use sterile swabs to collect saliva samples from the inside of the cheeks of the mother, father, and child. The collected samples will be sent to a paternity testing laboratory for processing. The time to complete the testing once a sample reaches the DNA testing lab is usually about three to five days. Sequential is the premiere source for DNA testing solutions. Schedule an appointment now online at *Alternatively, it is possible to test samples other than cheek swab samples. Non-standard samples require chain of custody paper and involve an additional fee.



DNA paternity testing is based on the fact that each person’s unique genetic blueprint is stored in material known as DNA. This DNA determines everything about us as human beings and is largely the same for all people. However, small differences in DNA between people determine each of our unique characteristics, including traits like eye color and blood type. There are also DNA differences that have no biological purpose, but which are useful for differentiating between or identifying people. Genetic markers for identity applications like paternity testing or forensic identification use these types of non-functional genetic differences. One type of such markers are called Short Tandem Repeats (STRs) because they have varying numbers of repeated segments of DNA. Another type are called Single Nucleotide Polymorphisms (or SNPs) because they have a variation in only a sing DNA base.


Paternity testing uses DNA that is found in every human cell in order to determine if someone is the parent of a child. Because each of us was born with unique DNA structures that were given to us by our parents, the resulting DNA will reflect both of our parents’ DNA. To determine a father’s identity, the DNA from the mother, child, and presumed father must all be compared. When enough pieces match, paternity can be determined to an almost certain degree.
