In addition to performing DNA testing on buccal swabs, DNA Solutions has 20 years of experience extracting DNA from non-standard samples. While the most common non-standard samples include blood stains, hair, semen, and a toothbrush, our laboratory has successfully obtained DNA from multiple non-standard sample types. Testing on non-standard samples does take longer than the standard turnaround time of two business days. Please allow at least six business days for cases containing non-standard sample types. Please reference price sheets or contact DNA Solutions for a quote, as these items will accrue additional fees.

In 2020, DNA Solutions has performed testing on 61 non-standard samples. Of those samples, only 8 items did not provide a full profile for testing. That is an 86% success rate! Although our laboratory cannot guarantee an item will provide a profile, we do use validated testing methods and trained analysist proficient in genetic testing. Our staff works diligently to obtain the most DNA possible. Our customer service representatives will communicate with you throughout the process. Should the DNA test not produce a comparable profile, there is an opportunity to submit a replacement sample. Clients are strongly encouraged to avoid shipping items overnight on Fridays, as the samples could degrade while sitting in a warehouse over the weekend. Always package your items in paper and not plastic, as plastic can cause moisture and bacteria which can contaminate and/or destroy the DNA on the sample. Items such as urine, whole blood, or body tissue should be shipped overnight with icepacks or dry ice. If you have questions regarding how to properly package and ship an item, please contact our facility at 866-362-9778.
