From monitoring organ function to testing for diseases, blood tests can reveal a lot about your health. But if it’s your first time or it’s been a while since you’ve had blood work done, you may have a few questions about the process. To help you prepare for the lab visit, here are some answers to a few frequently asked questions about blood testing.

5 Blood Work FAQs

Who Is Qualified to Draw Blood?

Phlebotomy, or the practice of drawing blood, is only regulated in certain states. As such, certified healthcare professionals, including nurses and physicians, can technically perform the practice. However, for accurate results and patient comfort, all lab tests should be performed by someone who has completed additional training in phlebotomy.

How Is Blood Drawn?

The process usually takes 15 minutes or less. During your lab visit, a phlebotomist will insert a thin needle into a prominent vein. Next, a vacuum tube gently suctions blood into a vial. When the sample is collected, the needle is removed and the insertion site is bandaged.

How Can I Make My Veins More Prominent?

Veins may not always be easy to find during blood work because of various reasons, including dehydration, stress, and temperature changes. Since water helps plump up veins, hydrating before your appointment can make them easier to find. You should also try to relax as much as possible since stress-related high blood pressure can narrow veins.

Are There Any Side Effects to Having Blood Drawn?

Depending on your physical health and the nature of the test, you may experience minor side effects. Most commonly, people will develop light bruising where the needle was inserted. In some cases, individuals may feel light-headed or dizzy, especially if they were instructed to fast before the test. Eating a snack after giving a sample can help.

When Can I Expect Results?

The amount of time it takes to receive blood work results can vary based on the nature of the test and your provider’s lab facilities. Typically, results are reviewed by your physician within 24 hours. However, some tests can take several days, especially if they’re processed at an off-site lab. For the best estimate, ask your physician or phlebotomist directly.
