Draw
(Redirected from Draws)
Draw is a term often used in medical procedures, specifically in the context of blood tests where a sample of blood is "drawn" from a patient for testing. The process of drawing blood is also known as venipuncture.
Procedure[edit | edit source]
The procedure of a blood draw typically involves the following steps:
- The healthcare provider will clean the area of the skin where the needle will be inserted. This is usually the inside of the elbow or the back of the hand.
- A tourniquet is applied above the area to be punctured to slow down blood flow and make the veins more visible.
- The healthcare provider will then insert a needle into a vein. The needle is attached to a small tube, which collects the blood.
- Once enough blood has been collected, the needle is removed.
- The puncture site is then covered with a bandage or cotton ball to stop any bleeding.
Uses[edit | edit source]
Blood draws are used for a variety of medical tests, including:
- Complete blood count (CBC)
- Blood chemistry tests
- Blood enzyme tests
- Blood tests to assess heart disease risk
