DNA samples are categorized into two types:
Oral swab with a cotton swab from the inside of the cheek (buccal epithelium scraping). The procedure is very simple and takes 5-7 minutes; you can view the instructions here. It can be easily done at home. Store samples in a regular paper envelope at room temperature.
Non-standard samples include all other types except the oral swab. Below are the most common ones:
