How Many Attempts Can a Phlebotomist Make?

phlebotomist attempts to draw bloodDrawing blood is a common and very important task in medicine. Phlebotomists are professionals trained to take blood from a vein, a procedure called venipuncture. Sometimes, getting blood isn’t easy, and it might take more than one try. So, how many attempts can a phlebotomist make on the same person in one sitting?

Limits on Trying to Draw Blood

Usually, a phlebotomist will try no more than twice to draw blood. This rule helps to keep the patient comfortable and safe from problems like bruising or hitting a nerve. If the phlebotomist can’t get blood after two tries, they should ask another experienced healthcare worker to try. If even the second person isn’t successful, it might be best to schedule another appointment. With this time, the patient’s veins can recover, and the phlebotomists can prepare better for next time.

Why Multiple Tries Might Be Needed

There are a few reasons why getting blood might take multiple attempts:

Hard-to-Find Veins

Some people’s veins are hard to see or feel. This could be because the veins are deep, small, or move around a lot.

Patient’s Health

Things like not having enough water in the body, being overweight, or certain health conditions can make veins harder to find.

Skills and Experience

The phlebotomist’s skill and experience matter a lot. Those who have more experience are often better at drawing blood successfully.

Thinking About the Patient

When a phlebotomist has a hard time drawing blood, it’s important to think about how the patient feels. Missing several times can make a patient worried and uncomfortable. So, phlebotomists must be kind and talk to the patient to keep them calm and in the know about what is happening.

Tactics to Help Find Veins

When it’s hard to find a vein, phlebotomists can use several tactics to make the veins easier to get to:

  • Hydration: Encouraging the patient to drink water before can plump up the veins, making them easier to find.
  • Heat: Applying a warm compress to the draw site can help by causing the veins to dilate or widen.
  • Gravity: Having the patient let their arm hang down by their side can help fill the veins with blood.
  • Tapping: Gently tapping the area above the vein can cause the vein to swell.


Keep Learning

It’s important for phlebotomists to keep learning new things. This means taking extra classes, getting new certifications, and practicing new skills. Learning more can help phlebotomists be more successful and improve the patient experience.


While phlebotomists usually only make two blood draw attempts, they must always consider the patient’s comfort. They should use their training and tools to make each try successful and keep the patient as comfortable as possible. Good phlebotomists keep learning and practicing to improve their skills. This helps them do their work well and makes the patients feel safer and more comfortable.
