During venipuncture, the phlebotomist inserts a needle through your skin into a vein. The amount of blood needed for the test is withdrawn through the needle into a special tube or tubes. The tubes are sent to a laboratory, where the blood is analyzed as the healthcare practitioner has ordered. Most often, the phlebotomist is able to identify a vein in the crook of your elbow that will be easily accessible and then applies a tourniquet above the site to make the vein more apparent. (The elbow area does not have many nerves so this is a good site; the wrist, hand and foot are other sites that can be used.) Making a fist when you are asked to helps make the vein more prominent. The procedure usually takes less than 3 minutes. Afterward, the patient is usually asked to apply gentle pressure over a clean dressing to help the blood clot and prevent swelling and a hematoma (a black and blue mark where blood has pooled).

When the needle is inserted under the skin, you might feel a slight sting, and there may be additional discomfort when it is withdrawn. If you are accompanying a child or an anxious patient, it helps to explain that he or she will feel momentary pain or discomfort. Don’t say, “This won’t hurt a bit,” because the patient will then have reason to mistrust the people and situation when it does sting. Be honest, create a reasonable expectation, and you will really help the patient.

Being well-hydrated helps blood flow better and makes the veins more likely to raise up and be found easily, so make sure you drink plenty of fluids a day or two before your test. But, also remember to follow your healthcare provider’s instructions—some tests require that you not drink certain liquids prior to the test. You may also want to take a walk while waiting, or on your way to the test, which raises blood pressure and can make veins more prominent (routinely doing hand and arm exercises also helps those requiring frequent testing). Even eating well the day before, if fasting is not required, improves blood flow.

Talk about or recall something pleasant while you wait to take your mind off your anxiety; you can also bring reading or music.

If you are nervous or have a tendency to feel woozy or faint, tell the phlebotomist before you begin. Your blood can be drawn while you are lying down, which will help you avoid fainting and injuring yourself. If, at any time, you feel faint or lightheaded, tell the phlebotomist or someone nearby. Putting your head between your knees or lying down should make you feel better soon.

You will need to fast for at least 12 hours before for the following tests:

  • Basic Metabolic Panel
  • Calcium
  • Glucose
  • GGT
  • FSH

A Southwest Labs phlebotomist will send you notifications prior to testing to ensure a successful testing protocol.
