Venous blood sampling

Venous blood sampling is a medical procedure where a small amount of blood is drawn from a vein, usually in the arm. This is typically done using a needle and a syringe or a special blood collection tube. The blood samples are then sent to a laboratory for analysis to help diagnose health conditions, monitor diseases, or check how well treatments are working. The procedure is quick and mostly safe, with minimal discomfort, and it provides important information about a person's overall health.
