Do not eat, drink, smoke or use chewing gum for 30 minutes before collecting samples of saliva so that no impurities are contained in the saliva and enough epithelial cells have accumulated. The process of collecting saliva itself is simple and painless, it usually takes no more than 5 minutes. Pay attention to the black mark on the tube, it is a mark of the amount of saliva (not the level of bubbles) that is essential for accurate analysis.
A barcode is applied to the tube - this is your unique genetic test number. You need to register it in your personal account on the DNA-28 website. If you are taking the test with your family or company, each participant can choose any tube. Be careful: it is important that the saliva in the test tube belongs to the person to whom its number is registered.
Do not swallow the solution. If the solution gets into the eyes or on the skin, wash them with plenty of water. If necessary, consult a doctor.
This device is intended only for collecting samples of human saliva.
A small cap can be choked. Children under 14 years collect saliva under supervision.
