Overview
Dried Blood Spot (DBS) sample collection uses a small amount of blood from a device that attaches to an athlete’s upper arm (or in some cases a finger prick).
The blood is collected and dried on absorbent material, then sealed securely and sent to a WADA-accredited lab for analysis.
This new method differs from a normal blood sample collection, which withdraws much more blood via a needle into a vein in an athlete’s arm.
