Kapillærpunktion
Kapillærpunktion, also known as finger‑stick or heel‑stick, is a minimally invasive technique for obtaining a small volume of blood from capillary beds, typically in the fingertip of an adult or the heel of an infant. The practitioner cleans the puncture site with an antiseptic, then presses a lancet or needle through the skin to create a capillary wound. The resulting blood is collected either in a microcollection tube or on a filter paper spot for transport.
This method is widely used in point‑of‑care testing, pre‑operative screening, and for home blood glucose monitoring.
Advantages of kapillærpunktion include ease of performance, reduced pain compared to venipuncture, lower risk of blood
In clinical practice, kapillærpunktion remains a staple of bedside diagnostics, particularly in settings where rapid, low‑volume
