Type of Sample for DNA Paternity Testing
Initiate Test | Participants | Type of Samples | Procedure | Understanding Results  
Every individual has a unique genetic profile (with the exception of identical twins) and the nuclear cells of a given individual, irrespective of tissue origin (may come from bone, muscle, blood, etc.) have the same DNA content. Therefore, virtually any type of biological sample/tissue can be used to generate a genetic profile.

The most efficient way to collect a DNA sample is through buccal swabs, as they are a non-invasive, non-traumatic, and fast means of obtaining amounts of DNA sufficient to perform DNA tests. In the past, blood was the common sample collected, whereas it can still be used, it does not have the aforementioned attributes of buccal swabs.

During sample collection, three buccal swabs (similar to Q-tips) are brushed gently (yet firmly) against the patient's inner cheek; through swabbing, epithelial cells shed from the inner cheek and adhere to the swabs. Then, DNA is extracted from these cells in the lab and used to carry out the test.

For our private paternity tests, buccal swabs can be collected in the privacy of one's own home by using ourFREE DNASwabTM DNA Collection Kit.

For legal paternity tests, an authorized third party must perform the sample collection to establish a chain of custody, as required by the court. If a legal test is needed, a sample collection appointment will be scheduled by a case consultant, upon case setup.

When a person may not be present for direct sample collection (i.e., the person is deceased, missing or unwilling), other types of samples can be used, such us semen, hairs with roots, nails, blood stains, cigarette butts, toothbrushes, etc. These samples are considered to be forensic samples, and while it is not guaranteed that data will be obtained (due to the nature, size and variability of these type of samples), often, enough viable DNA is present to obtain a partial or full genetic profile.

"I just want to thank the continued professional and courteous service your Customer Service team provided me during the stressful waiting period for the DNA results. I contacted both your phone support and instant chat support teams at least twice and received concerned support each time. Never did I feel like they thought I might be calling too much and needed to be more patient. I truly appreciate their consideration and patience during this time."
