Kapillärutstryk

Kapillärutstryk is a medical procedure used to collect a small blood sample. It involves making a tiny puncture in the skin, typically on a fingertip or heel, using a lancet. The resulting drop of blood is then collected in a capillary tube, which is a very thin glass tube. This method is commonly used for diagnostic tests such as blood glucose monitoring, hemoglobin analysis, and newborn screening. The small volume of blood required makes it a less invasive option compared to venous blood draws, particularly for infants and young children. The capillary tube's narrow diameter utilizes capillary action to draw the blood into the tube. After collection, the sample is often sealed and sent to a laboratory for analysis. The procedure is generally quick and well-tolerated by patients. Precautions are taken to ensure sterility and proper sample handling to maintain accuracy.
