What You Need to Know About Blood Testing
Preparation: Blood tests typically require that you fast for at least 8 hours prior to the test being given. Your doctor will likely advise you of any special instructions that you need to follow in order to prepare for the test. Additionally, many tests require that you abstain from alcohol for up to 24 hours prior to the test being administered.
Procedure: The most common method of a blood test is to draw blood from a vein in your arm. Procedure may vary slightly, depending on the type of test and what your doctor is targeting. The process requires your arm to be cleaned with an antiseptic solution and then a band will be placed around your arm to help the vein become more prominent.
The healthcare practitioner collecting the blood will then use a needle to draw blood. Generally, blood is collected from both arms to make the process less painful. A bandage may be placed to stop bleeding and the site can then be cleaned with antiseptic.
