DBS
Also written as: DBS — dried blood spots
Dried blood spots collected on filter paper for newborn screening laboratory analysis.
Full Definition
Dried blood spots (DBS) are blood samples collected from newborns and allowed to dry on specialized filter paper cards. This collection method preserves analytes for extended periods and allows for efficient shipping and storage. DBS samples are punched from the filter paper cards using automated equipment, then analyzed using various techniques including tandem mass spectrometry and immunoassays. The DBS format is the global standard for newborn screening programs due to its stability, ease of collection, and suitability for multiple analytical methods.
