Details | Oral swabs, or single-source DNA samples provided on cotton tips, are considered ‘standard samples’ and are used in the majority of DNA tests involving living people. However, in some cases, it is not possible to obtain a standard sample, and unusual samples are instead accepted. ‘Unusual samples’ are mixed-source samples, nail clippings, toothbrush, bed sheet, hair with root attached, etc., and they must undergo DNA extraction before DNA testing can begin. Therefore, most unusual samples will incur a fee. Please contact us to have a confidential discussion about the type of sample you wish to submit. |
