buccal smear

Often a small sample of cells can be scraped from inside the cheeks (this is called a buccal smear).

When this disorder is suspected, a buccal smear is the first test to request.

As a first step, the presence of DYZ1 was determined with lysates of buccal smears from female competitors and two specific primers.

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.

The physical risks associated with most genetic tests are very small, particularly for those tests that require only a blood sample or buccal smear (a procedure that samples cells from the inside surface of the cheek).
