Dried Blood Spot

Meaning

Dried Blood Spot (DBS) refers to a simple, minimally invasive clinical specimen collection technique where a small, precisely measured volume of blood, typically acquired via a finger prick, is actively absorbed and allowed to dry onto specialized filter paper. This standardized method is routinely utilized for the stable collection, transport, and subsequent quantitative laboratory analysis of a wide range of biomarkers, including steroid hormones, metabolic indicators, and therapeutic drug levels. It offers a convenient, patient-friendly alternative to traditional venipuncture for both remote and at-home diagnostic testing.
