What samples should be provided for paternity test?

There are many kinds of samples for paternity testing, which can provide blood samples, nail samples, hair samples, oral samples and so on. Among them, the hair sample needs to put the newly pulled hair (with hair follicles) into the marked envelope immediately. Collecting hair samples is not limited by time and place, and it is the simplest sampling method with high concealment and accuracy completely consistent with sampling methods such as blood collection.

Hair paternity test:

The reason why hair can be paternity tested is because there are complete hair follicles at the bottom of the hair. Only hair follicles can be used as a standard for identification. If the hair falls off naturally and the hair follicle is incomplete, it may not be possible to make an identification result, let alone cut the hair.

In fact, not only hair, but also human hair can be recognized, but hair is generally chosen because the development of hair is more complete than other hair. Be sure to pull your hair down. Pay attention to whether there are small white or black meat particles clearly visible to the naked eye at the bottom. Only hair that meets the requirements is qualified.

After the hair is pulled out, put it on a clean piece of white paper, and never touch the hair follicle with your hands. This will lead to the pollution of the sample, increase the difficulty of the experiment, and it is very likely that no results will be obtained. Therefore, to ensure that hair follicles are clean and pollution-free, put them in a clean envelope bag, and generally 3-5 hairs with hair follicles will do.
