Would a DNA sample other than swabs (hair, blood) be more accurate?

Cheek swabs are considered the most reliable and convenient method of sampling DNA. In cases where it is not possible to use a swab, we will accept alternative samples, though we cannot guarantee a successful result with these samples. Because of this uncertainty, we will initially carry out a viability test to ascertain if there is enough DNA present. If this is successful, you can progress to a standard DNA Test. Please note that the viability test carries an additional charge. You can contact us for more details.
