blood from a finger or a vein for rent on an empty stomach.Collection of saliva also occurs in the tube before toothbrushing.If you want to do a DNA test without the knowledge of any person, then you take the above samples in medical gloves or use clean tweezers, a sheet of paper.
from one person need a few samples of DNA to get an accurate result.Forward they need in a paper envelope.Note that in the wet toothbrushes, chewing gum, razor and other items in the envelope can not be put.Wait until they are dry.
collection of saliva in the home.Modern technology
How do DNA testing at home?Find a medical institution and make a special delivery tubes.Next, gather the necessary materials in separate containers and send them by mail, courier or by self clinic.Saliva can be collected in the following way:
- medical gloves, take a clean sheet of paper and fold it four times;

found that the composition is similar to placental DNA child.Therefore, when the cells die placenta and enter the mother's blood, then with the help of complex bioinformatics algorithms fetal DNA is released and established relationship with his father.

Please note that not all of Russia is carried out DNA tests, many laboratories use the services of foreign clinics.Because the cost can be very expensive, but reliable.The fact that the self-ordering analyzes abroad, many letters are returned back to the client in connection with a mail policy.
time DNA testing could range from 4 to 10 days.Rush Order is an order of magnitude higher.Choosing a foreign facility, look carefully, because DNA tests do not only people but also animals.
