A blood collection card (also known as a dried blood spot collection card, Dried Blood Spot, DBS) is a paper or cellulose-based card specially used for collecting, storing and transporting trace blood samples. It forms a dried blood spot by absorbing a small amount of blood (usually 50-100μL) and drying it naturally in the air, which is convenient for long-term storage and subsequent laboratory testing.
Main components
Filter paper substrate: high adsorption, no heavy metal pollution
Marking area: clear blood collection location (circle with a diameter of about 1cm)
Anti-fouling layer: prevent cross-contamination
Tearable design: convenient for laboratory sampling
II. Working principle of blood collection card
IV. Application areas of blood collection cards
Congenital hypothyroidism
Genetic metabolic disease detection
New coronavirus serological survey
Pharmacogenomic analysis
Drug abuse screening
V. Steps for correct use of blood collection cards
Preparation before blood collection
Disinfect the blood collection site (fingertips/heels) with alcohol
Use a disposable blood collection needle
Blood dripping operation
Let the blood flow out naturally and touch the card marking area
Avoid repeated application to prevent hemolysis
Drying and storage
