Having blood drawn is different for everyone. Some people aren't bothered by it at all, while others worry that they may pass out at the sight of a needle. In the hands of a skilled phlebotomist or nurse, a blood draw shouldn't be painful, but you may experience some brief discomfort. Regardless of whether having your blood drawn is no big deal or a major issue for you, some quick preparation for your blood draw can make the process much easier.

How Blood Is Drawn

The procedure for drawing blood, called venipuncture, is simple. In most cases, your blood will be drawn by a nurse or a phlebotomist — a person specially trained to draw blood. First, the site of the blood draw is cleaned with alcohol or another cleanser which will clean the area and remove germs. Then a tourniquet is tied above the site of the draw — such as the upper arm — to maximize the amount of blood in the vein while blood is drawn. Once the tourniquet is in place, a needle is gently pushed into the vein, and blood is collected. While the blood is being collected, the tourniquet is typically removed to allow blood to flow more easily. Once the blood has been drawn, the needle is removed, and pressure may be held on the site for a short while — or a small bandage may be placed over the site.

There are many blood tests that will obviously necessitate blood draw, and if you're having surgery, multiple blood tests may be necessary to determine if you're a good surgical candidate.

Preparing to Have Your Blood Drawn

Full veins are plumper than veins that aren't as full. If you're having blood drawn, unless you've been told not to eat or drink, make sure you are well-hydrated. This simple step will make it far easier for the person who is taking your blood to find a vein that can easily be punctured, and far easier for you because your veins will be much easier to find and access.


Ideally, start drinking more fluids the day before your blood draw, and continue to drink water before you have your blood drawn. Excessive amounts aren't necessary; most sources recommend that an adult drink 64 ounces of water per day for good health, which is more than adequate for having your blood drawn. Limit caffeine, which acts as a mild diuretic and increases the amount of urine you produce.

Tips to Help Stay Calm During Blood Draws

1. Breathe

Don't hold your breath while blood is drawn. Some people hold their breath in anticipation of the insertion of the needle, which doesn't help at all if you're feeling faint. Keep breathing at your normal rate and depth, and you'll be far less likely to feel lightheaded during a blood draw. If the potential for pain is making you nervous, the phlebotomist may have numbing medication available to minimize the pain.

2. Be Honest

If you are someone who has fainted in the past when donating blood or having your blood drawn, be sure to tell the person who will be drawing your blood. If there is the slightest chance of fainting during a blood draw, positioning is key. You shouldn't sit on top of the exam table; rather, you should be positioned in a low chair where falling is unlikely.

3. Don't Look

If having your blood drawn makes you feel queasy, don't watch while your blood is drawn. For some, the sight of blood is the problem, so not watching while blood is collected can easily solve that problem. Look away, read a magazine, or watch television or whatever will distract you from the procedure.

4. Ask For Someone Else

If the person drawing your blood isn't successful after two tries, it's reasonable to ask for another nurse or phlebotomist to try. Don't allow yourself to be turned into a pin cushion for an inexperienced practitioner or someone who is struggling to find a vein to use.

The phlebotomist may also try using a smaller needle, called a butterfly needle, which is large enough to draw blood but often works well on small veins. Stand up for yourself if you need to!

5. Sit Still

If you're moving and wiggling while someone is attempting to draw your blood, it's likely that he will have to make more attempts to obtain the sample. Sit still. Even if you are nervous, it's important to refrain from wiggling and fidgeting, or you could potentially add to the number of pokes required to draw your blood.

6. Ask For Numbing Medication

There are medications that can be rubbed on the skin where a draw will be performed a few minutes prior to the procedure that numb the area. If you find having your blood drawn very painful, consider asking for a numbing agent prior to the draw, if it is available.  The effect is temporary and is the medication is only used on a small area, so it is considered very safe.  It is most frequently used for young patients but is available for adults as well.
