Discreet Samples In Paternity Testing

Sometimes a parent taking the test may wish to act more discreetly, in order to save others or the children from unnecessary stress and anxiety, if taking a buccal mouth swab sample is too difficult, DNA Test is also able to test discreet samples.

Discreet samples:

Blood stained garments, chewing gum, cigarette butt, licked envelope, licked stamp, semen stain, skin tissue, toothbrush, fingernail clippings, snotty tissue, hair, earwax on cotton bud, used band aid. When handling discreet samples, it is important not to contaminate samples.
