Phlebotomy certification and licensure requirements are set at the state level, which means the rules can look completely different depending on where you work. Some states require a specific state license. Others accept national certification. Many have no formal requirement at all. This guide breaks down the current landscape and explains what “requirements” actually means in practice.
Understanding the Difference: Certification vs. Licensure
Certification is voluntary credentialing granted by a professional organization (ASCP, NHA, NCCT, AMT) after you pass their exam. It proves competency but is not a government-issued legal requirement to practice unless a state law or employer requires it.
Licensure is a state government-issued legal authorization to practice. You cannot legally work as a phlebotomist in a state that requires a license without having that license. Licensure typically requires meeting education, training hours, and exam requirements, and often must be renewed on a set schedule.
In states without licensure laws, employers set their own requirements. Many hospitals and large lab networks require national certification from ASCP, NHA, or an equivalent body even where the state does not. So “no state requirement” does not mean “no certification needed.”
States with Mandatory Phlebotomy Licensure
California
California is the most regulated state for phlebotomy. The California Department of Public Health (CDPH) licenses phlebotomists under the Laboratory Field Services division. California has multiple phlebotomy certificate levels:
Phlebotomy Technician I (CPT I): Entry level. Requires completion of a CDPH-approved phlebotomy training program (typically 40 hours didactic + at least 40 successful venipunctures + 10 capillary sticks), passing an approved national exam, and paying the state license fee. Valid for 2 years, renewed with continuing education.
Phlebotomy Technician II (CPT II): Expanded role. Requires CPT I plus additional supervised draws and a separate exam.
Working as a phlebotomist in California without a CDPH license is a misdemeanor. California does not waive this requirement even for out-of-state certified phlebotomists. You must apply for California licensure separately.
Louisiana
Louisiana requires phlebotomist licensure through the Louisiana State Board of Medical Examiners. Requirements include completing an approved training program, national certification from an approved certifying body, and application with the state board. License must be renewed every two years.
Nevada
Nevada requires phlebotomists who perform skin puncture and venipuncture to hold a state health card (issued by the county health district) plus meet employer-specific training requirements. Hospital and clinical lab employers in Nevada also typically require national certification.
Washington
Washington State requires phlebotomists in clinical laboratory settings to hold a state credential through the Washington State Department of Health (DOH). Credential types and requirements are tiered. National certification from an approved body (ASCP, NHA, AMT, NCCT) satisfies the examination component.
States That Recognize National Certification Without Separate Licensure
Most states fall into this category. You don’t need a state-issued phlebotomy license, but employers — especially hospitals, physician office labs, and reference labs — require national certification from one of these bodies:
ASCP Board of Certification: Phlebotomy Technician (PBT). Most widely recognized in hospital settings. Required by many large health systems as a condition of employment.
National Healthcareer Association (NHA): Certified Phlebotomy Technician (CPT). Widely accepted, slightly more accessible exam format for entry-level candidates.
American Medical Technologists (AMT): Registered Phlebotomy Technician (RPT). Accepted by most employers that accept ASCP or NHA.
National Center for Competency Testing (NCCT): National Certified Phlebotomy Technician (NCPT). Less common but accepted at many facilities.
States in this group include: Texas, Florida, New York, Illinois, Pennsylvania, Ohio, Georgia, North Carolina, Michigan, New Jersey, Virginia, Arizona, Massachusetts, Tennessee, Indiana, Missouri, Maryland, Wisconsin, Colorado, Minnesota, South Carolina, Alabama, Kentucky, Oregon, Oklahoma, Connecticut, Utah, Iowa, Mississippi, Kansas, Nebraska, Idaho, West Virginia, Hawaii, New Hampshire, Maine, Rhode Island, Montana, Delaware, South Dakota, North Dakota, Alaska, Vermont, and Wyoming.
In all of these states, your employer is your regulatory authority. Check the specific job posting for requirements, most hospitals and labs will list their certification requirement in the minimum qualifications section.
States with No Formal Requirement
A small number of states and jurisdictions have no state law requiring certification or licensure for phlebotomists. This does not mean you don’t need to be qualified, it means the requirement falls entirely on the employer.
In practice, any lab or hospital drawing blood for clinical testing falls under CLIA (Clinical Laboratory Improvement Amendments), a federal law. CLIA requires that personnel performing testing (and specimen collection is part of testing) be qualified through training, education, or experience. Most CLIA-regulated facilities satisfy this by requiring national certification or documented training.
How to Verify Current Requirements
State requirements change. The safest approach:
1. Check your state’s department of health or laboratory licensing agency directly. Search “[your state] phlebotomy licensure” to find the relevant agency website.
2. Check ASCP’s state-by-state requirement guide (available on their website).
3. Review job postings in your target state — employer requirements reflect market standards even when the state has no law.
4. Contact the state board if you plan to relocate. California in particular processes licenses slowly; apply well before your planned start date.
What About Multi-State Work?
If you plan to work in multiple states (travel phlebotomy is a growing field), you’ll need to comply with each state’s requirements separately. National certification from ASCP or NHA travels with you across states that recognize it. California and Louisiana require separate state-specific applications regardless of your national certification status.
The Practical Takeaway
Get nationally certified. ASCP PBT or NHA CPT covers you in virtually every non-California state and demonstrates clinical competency that matters to employers even where no law requires it. If you’re in California, you need national certification plus CDPH licensure — plan for the added time and cost.
