Phlebotomy exam?

To actually be certified, yes, there is a written exam. There are a couple different organizations you can choose from to do that. But be aware that most states don't require certification and most employers don't pay more for certification.

I don't know anything about the EKG situation.

For some reason I am unable to go back and type in the middle of that first sentence, but it refers to phlebotomy.

To be a certified phlebotomist, do you have to take a practical exam or written exam?

What are the requirements for EKG exam?

ASCP (American Society of Clinical Pathologists) is one certifying body. Assuming you can find a facility that maintains a phleb team, it would demonstrate proficiency that could bring more $, as a "Senior Phleb". Written exam, with 2 year work experience pre-requisite. It may also help you, if you get into nursing education.

I'm not sure about the EKGs...
