A buccal swab, also known as buccal smear, is a way to collect DNA from the cells on the inside of a person's cheek. Buccal swabs are a relatively non-invasive way to collect DNA samples for testing .
A genealogical DNA test is performed on a DNA sample obtained by cheek-scraping (also known as a buccal swab), spit-cups, mouthwash, or chewing gum. Typically, the sample collection uses a home test kit supplied by a service provider such as 23andMe, AncestryDNA, Family Tree DNA, or MyHeritage. After following the kit instructions on how to ...
These swabs have wooden or plastic stick handles with a cotton on synthetic tip. The collector rubs the inside of a person's cheek to collect as many buccal cells as possible, which are then sent to a laboratory for testing. Samples from the alleged father or mother and the child would be needed.

For example, a medical procedure called a buccal smear uses a small brush or cotton swab to collect a sample of cells from the inside surface of the cheek. Alternatively, a small amount of saline mouthwash may be swished in the mouth to collect the cells.
Rapid DNA (UK:Rapid DNA profiling) describes the fully automated (hands free) process of developing a CODIS Core STR profile or other STR profile from a reference sample buccal swab. The “swab in – profile out” process consists of automated extraction, amplification, separation, detection and allele calling without human intervention. [1]
Tips to clean your ears — and why ENTs want you to stop removing ear wax with cotton swabs and at-home irrigation kits. Sarah Hunter Simanson. June 27, 2024 at 5:00 AM.
For the chemical method, many different kits are used for extraction, and selecting the correct one will save time on kit optimization and extraction procedures. PCR sensitivity detection is considered to show the variation between the commercial kits. [5] There are many different methods for extracting DNA, but some common steps include:
