Venipuncture (blood sampling method)

Venipuncture is a medical procedure used to collect blood samples from a person’s veins, typically in the arm. A healthcare professional cleans the skin, uses a small needle to puncture the vein, and draws blood into a special tube. This method is commonly used for various tests, such as checking for infections, measuring nutrient levels, or assessing overall health. The procedure usually takes only a few minutes and may cause mild discomfort, but it is generally safe and well-tolerated. Care is taken to minimize pain and ensure cleanliness during the process.
