Dental swab collection, specific steps: 1. Prepare a medical swab (single head), extend it into the cavity, and wipe it more than 20 times from the mucosa of the cheeks inside the mouth (inside of the cheek), remove the cotton swab, and dry it on a clean white paper. 2. Collect 5 cotton swabs in the same way. 2. Store in a clean paper envelope after cool and dry. Don't forget to mark the sample. Do not make physical contact with other people. The samples collected by the above method can be stored in a dry environment for 2-3 months.
No matter what samples are collected, the accuracy of the identification results is the same. Because the sample collection only extracts DNA from it, and everyone's DNA remains unchanged for life, so even if different samples are collected, the accuracy of the identification results is the same.
