hair follicles
hair sample is used for paternity testing, and the part of the hair follicles can be seen by the naked eye. You can know that this amount is not a lot. Therefore, generally, for paternity testing, you should collect a few more hairs. At the same time, since the number of nucleus cells that can be detected in the hair follicle area is not very large, you should send the hair sample to the test as soon as possible after collecting hair samples to avoid too long. After too many cells lost by the hair follicle, the DNA information of the sample cannot be detected. Generally, hair follicle samples should be replenished for more than one year. Hair samples are not suitable for long-term storage. If you want to store samples for paternity tests for a long time, you can collect blood marks or oral swabs.
