NHA CPT vs ASCP PBT: which phlebotomy cert?
They're the two phlebotomy certifications you'll see most in the US. Both get you hired — but they're valued a little differently depending on where you want to work. Here's how to choose.
Quick answer: The NHA CPT is the most common entry-level credential employers ask for. The ASCP PBTcarries extra weight if you're aiming for hospital or clinical-lab roles. Many phlebotomists start with one and add the other later.

NHA CPT — Certified Phlebotomy Technician
Issued by the National Healthcareer Association, the CPT is the credential most US employers recognize for entry-level phlebotomy. It's a common requirement at clinics, physician offices, and draw stations, and it's often the first certification new phlebotomists pursue. The exam is multiple choice and assumes a completed training program plus some hands-on experience.
ASCP PBT — Phlebotomy Technician
Issued by the ASCP Board of Certification, the PBT is especially well regarded in hospital and clinical-lab settings, where ASCP credentials are seen as a high standard. If your goal is laboratory work, the PBT can carry extra weight with employers. Like the CPT, eligibility routes generally combine training with documented clinical experience.
So which should you choose?
- Starting out and want the most widely accepted entry credential → NHA CPT.
- Aiming for hospital or clinical-laboratory roles → ASCP PBT.
- Not sure yet → start with the CPT, then add the PBT as you move toward lab work.

Frequently asked questions
Is NHA or ASCP better for phlebotomy?
Both are strong, nationally recognized credentials. NHA's CPT is the most common entry-level ask and is widely accepted by clinics and employers. ASCP's PBT carries extra weight in hospital and clinical-laboratory settings, where ASCP certifications are highly regarded. The 'better' choice depends on where you want to work.
How much does the phlebotomy certification exam cost?
As of recent figures, the NHA CPT exam costs around $155 and the ASCP PBT exam around $135. Fees change over time, and training, supplies, and any required clinical hours are separate — always confirm current pricing with the certifying body before you register.
Do I need experience or clinical hours to sit for these exams?
Usually yes. Both bodies offer several eligibility routes that typically combine completing a training program with documented hands-on experience (a set number of venipunctures and capillary draws). Requirements vary by route — check the issuer's current eligibility table.
