Phlebotomy Technician PBT (ASCP) Certification

Phlebotomy is an important part of the healthcare system, and those hired in this field work in-demand, entry-level jobs.

The job of a phlebotomist is to draw blood for diagnostic purposes, donations, or other tests.

No matter where they work if they hold a post-secondary degree and certification, they have access to many rewarding and lucrative job opportunities.

In 2020, the U.S. Bureau of Labor Statistics predicted this profession will grow by 17% between 2019 and 2029, whereas most other occupations see a growth of around 4%.

People are expected to see 22,800 fresh new positions in this field.

Across the nation, at the time we write this guide, phlebotomists earn on average $35,000 per year, though this number is expected to change.

Facilities hiring uncertified personnel for this field are few and rare in-between, even if the candidates possess some experience and knowledge of the occupation.

Certification proves competency and helps individuals earn higher salaries in this growing field.

Those who want to become certified phlebotomists are expected to:

  • Have a high school diploma or GED
  • Join training programs that generally last for less than 1 year
  • Pass an exam

If you want to become a phlebotomist, you need to join a program with accreditation from the National Accreditation Agency for Clinical Laboratory Sciences (NAACLS).

These programs have 4 components:

  • 2 courses
  • Clinical practice
  • Internship

The best programs are held at the post-secondary level.

Individuals also need to know there are a few other ways to start a phlebotomy career, that we’ll present later.

State Certification for Phlebotomy Technicians

The majority of facilities hiring phlebotomists prefer their staff to be certified.

The certification can be from any accredited organization in the United States.

One example is the  American Society for Clinical Pathology (ASCP).
