- The tourniquet should exist put on the arm well-nigh four inches higher up the vein.
- A claret pressure level cuff that is inflated to 40–60 mm Hg also works well.

Use proper palpation techniques. Contrary to popular civilisation, yous should palpate the arm, rather than slapping it. Slapping the pare is poor technique that may result in a hematoma. Use your alphabetize finger to look for a vein, which feels soft and spongy. Don't use your thumb, as it contains its own pulse.
- The warm pack or water bottle should exist put on the expanse before it is disinfected. Null more should touch the area afterward it is disinfected.
- Do non utilize the warm pack or water bottle straight to the pare. Wrap information technology in a thin towel to prevent burns. If it hurts, it is likewise hot.

Locate the vein. The within of the elbow is generally the preferred location because the median cubital vein is usually easily visible. ^[five]
- The median cubital vein runs between the muscles and may be clearly visible equally a blue bulge in the within of your elbow. If information technology cannot be seen it can unremarkably be felt. It is also relatively easy to access because the tissue around information technology prevents information technology from rolling away from the needle.
- Avoid cartoon claret from a place where your veins dissever or bring together together. Doing so increases risk of haemorrhage nether the skin.
3
Disinfect the area. A common disinfectant is 70 per centum booze. Wipe an area that is at least two centimeters by two centimeters for at least a half a minute. Afterwards a minute or two it will have dried.^{[half dozen]}
- Alcohol is better than iodine considering if the iodine gets into the blood information technology can alter values that the lab may be looking for. If you do use iodine, follow it with a lxx% alcohol swab.
- Allow the disinfectant to dry before inserting the needle. Do not blow on or fan information technology with your hand as this volition contaminate the area.
4
Perform the venipuncture. ^[7]
- Anchor the vein by pulling the skin below the vein taut. This will foreclose the vein from rolling.
- Insert the needle in at a 15 to thirty degree angle and so concord it still while collecting blood.
- Fill the collection tube with claret, following the order of describe as specified by your laboratory.

Look for another vein if the median cubital vein is not visible. If you cannot find the vein in the inside of the elbow in either arm, look for some other one.^[9]
- Move down the forearm looking for the basilic vein or cephalic vein. These veins may too be visible through the skin. Have the patient lower their arm and make a fist to make the veins more obvious.
- The cephalic vein runs along the radial side of the forearm. The basilic vein runs forth the ulnar side. The basilic vein is less often used than the cephalic. It is more likely to whorl away from the needle than the cephalic vein because it is not held as tightly in identify past the tissues around information technology.
- If no veins tin can be accessed, find the metacarpal veins on the back of the hands. They are unremarkably very visible and can be palpated. They should not be used for elderly patients because the skin is not equally supple and does not support the veins as well. In addition, the veins themselves become more fragile.

Find sites to avert. Do not draw blood from areas that:
- Are near an infection
- Accept scarring
- Have a healed burn
- Are on an arm that is on the same side every bit where the patient had a mastectomy or fistula placed
- Are bruised
- Are in a higher place an IV line
- Are on an arm where the patient has a cannula, fistula, or vascular graft
3
Correct improper needle placement. Occasionally, you may meet bug with the needle, such equally going too far into the tissues or inserting it at too low of an angle (then the bevel is confronting the wall of the vein and impedes claret flow).^[ten]
- Pull the needle dorsum a little bit without removing information technology from the pare.
- Alter the angle of the needle while information technology is still under the peel so that it can be inserted into the vein.

Surrender and take a colleague practice the procedure if your second endeavour fails. Protocol in many laboratories dictates that phlebotomists must attempt a venipuncture two times, and to take some other person practice it if both attempts are unsuccessful.^[11]
