Genetic testing is the technique of detecting DNA from blood, other body fluids, or cells.

Genetic testing can determine individuality, and can also determine the characteristics of its population (ancestral origin) through group comparison. The haystack needle first narrows the area and then tests the individuality. Briefly explain the saliva sampling precautions that have been done before.

Precautions

1. 30 minutes before sampling, do not eat, smoke, or drink.

2. The head of the sampling swab must not be in contact with other objects such as cheeks, fingers, teeth, etc. If you accidentally touch the swab or the swab comes off during the sampling process, please use a new sampling swab to resample.

3. Do not use if you find the package unopened or damaged.

Collection method

The DNA Test Swabs consists of a sampling cotton swab head, a sleeve and a putter. Its purpose is to collect and preserve exfoliated cells of the oral mucosa.

You can do it yourself whether you are at a medical examination center, company or at home.

First rinse your mouth with water 2-3 times to ensure your mouth is clean. Then take out the mouthpiece, press the cotton swab head of the Oral Swabstick lightly on the inner wall of the mouth, and make the cheeks slightly convex, once for up and down, and scrape 20 times.

After wiping, insert the cotton swab head into the sample collection tube, push the back of the swab with your finger, drive the cotton swab head into the tube, screw the tube cap tightly, and shake well.

Then take another oral swab and repeat the action on the other side of the oral cavity. The collected sample DNA can be stored at room temperature.

There are many types of bacteria in the human oral cavity. The normal flora of the oral cavity plays a role in maintaining the normal health and function of the host. However, some bacteria in the normal flora can cause disease even when the host's general resistance and local immunity are low. Medical institutions use oral swabs to study the distribution of routine bacteria in oral patients.
