Several types of healthcare professionals can legally draw blood, including phlebotomists, nurses, doctors, medical assistants, paramedics, and respiratory therapists. The specific rules depend on the setting, the type of blood draw, and the state where it happens. Here’s a breakdown of who does what and what training each role requires.
Phlebotomists
Phlebotomists are the specialists. Drawing blood is their primary job, and they perform the majority of routine blood draws in hospitals, clinics, and diagnostic labs. To become certified, a phlebotomist needs a high school diploma and completion of a training program, which typically takes a few weeks to a few months. Before sitting for the national certification exam, candidates must document at least 30 successful venipunctures (draws from a vein) and 10 capillary or finger sticks on live patients.
People who skip formal training can still qualify through work experience: one year of supervised phlebotomy work within the last three years, or two years within the last five, along with the same minimum number of documented draws. The two-hour certification exam is offered through organizations like the National Healthcareer Association (NHA), the American Society of Clinical Pathology (ASCP), and several others.
Nurses
Registered nurses (RNs) draw blood routinely, especially in hospitals, emergency departments, and outpatient clinics. Venipuncture is a standard part of RN training and falls within their scope of practice in every state. RNs can also access central venous lines (ports or PICC lines already placed in larger veins) to collect specimens, following their facility’s protocols.
Licensed practical nurses (LPNs), sometimes called licensed vocational nurses (LVNs), have a narrower scope. Whether an LPN can perform venipuncture depends on the state. In many states, LPNs can draw blood under the general supervision of an RN or physician, but some states restrict or prohibit it entirely. LPNs considering blood draws should check their state’s nurse practice act for specifics.
Doctors and Physician Assistants
Physicians and physician assistants (PAs) are authorized to draw blood, though in practice they rarely do routine draws because other staff handle the volume more efficiently. The World Health Organization notes that even physicians who perform blood sampling need structured training and supervision to do it safely. Doctors are more likely to perform specialized draws, such as arterial blood samples, or to draw blood during procedures when other staff aren’t available.
Medical Assistants
Medical assistants (MAs) frequently draw blood in physician offices and outpatient clinics. Their authority to do so comes through delegation: a supervising physician authorizes the MA to perform venipuncture. Scope of practice laws for medical assistants vary by state, and some states require MAs to hold a specific certification before performing blood draws, while others allow it as a delegated task with appropriate training. If you’re an MA, the American Association of Medical Assistants tracks state-by-state scope of practice laws that spell out exactly what’s permitted where you work.
Paramedics and EMTs
Paramedics are trained in venipuncture and routinely start IVs and draw blood in the field. EMTs, who have less training, generally cannot draw blood while working on an ambulance. However, the rules shift when EMS providers work inside a hospital. Virginia’s Office of Emergency Medical Services, for example, clarifies that an ED technician with EMT certification can be authorized by the hospital to perform phlebotomy and place IV catheters, even though those skills fall outside the EMT scope of practice in the prehospital setting. This kind of facility-based authorization is common across many states.
Respiratory Therapists
Respiratory therapists draw a specific type of blood sample: arterial blood gases. This involves puncturing an artery, usually in the wrist, to measure oxygen and carbon dioxide levels. It’s a more specialized and painful draw than a standard venipuncture, and respiratory therapists are specifically trained for it as part of their role managing ventilators, oxygen therapy, and other breathing support.
How State Laws Change the Rules
There is no single national license for drawing blood. Each state sets its own requirements, and the differences can be significant. California is one of the strictest states, requiring phlebotomists to hold a state-issued certificate. California recognizes two levels: a Certified Phlebotomy Technician I (CPT I) can perform skin punctures and venipunctures, while a CPT II can also perform arterial punctures. The CPT II requires at least 1,040 hours of on-the-job phlebotomy experience and a minimum of 20 documented arterial punctures, plus passing a national certification exam.
Texas requires phlebotomy technicians to be licensed through the Texas Department of Licensing and Regulation, complete an approved training program, and meet continuing education requirements. New York requires licensure as a clinical laboratory technician through the state education department. Other states have minimal or no specific phlebotomy licensing requirements, relying instead on employer-based training and oversight.
Mobile and Home Blood Draws
Mobile phlebotomy services, where someone comes to your home to draw blood, have grown in popularity. The person drawing your blood in this setting must meet the same licensing and certification requirements as someone working in a lab or clinic. In states like California and Texas, that means holding a state-issued license or certification. Mobile phlebotomy businesses must also follow infection control protocols, maintain proper documentation, and protect patient privacy, just as a hospital lab would.
Safety Training Everyone Must Complete
Regardless of their title, anyone who draws blood must complete bloodborne pathogens training mandated by OSHA. Employers are required to provide this training when a worker is first assigned to a role involving blood exposure, then at least once a year after that. The training covers how bloodborne diseases spread, how to prevent exposure, and what to do after an accidental needlestick. Employers must also offer the hepatitis B vaccine to all workers with occupational blood exposure, free of charge, within 10 days of starting the job.
The Clinical and Laboratory Standards Institute (CLSI) publishes the widely used GP41 guidelines, which lay out a step-by-step process for venous blood collection. These standards cover everything from the correct order of draw tubes to handling pediatric patients and drawing from vascular access devices. When facilities follow these standards consistently, the risk of patient injury, contaminated specimens, and unreliable test results drops significantly.
