FAQ

Diagnostic Technician questions.

Which certifications can I sit?

ASCP-BOC phlebotomy (PBT), AMCA ECG/EKG, and NHA Certified Clinical Medical Assistant (CCMA) are all aligned with our curriculum. Most graduates pursue 2–3 of these in their first year.

Is this the same as a Radiologic Technologist?

No. Radiologic Technologist (RT) is a 2-year associate degree with full diagnostic imaging scope. Diagnostic Tech is a broader multi-skill credential — a feeder track for RT and a destination role for outpatient/lab work.

Can I work in a hospital?

Yes. Hospitals hire phlebotomists, ECG techs, and patient care techs with diagnostic backgrounds. The multi-skill credential makes you flexible across departments.

Where will my externship be?

Hospital diagnostic departments, outpatient lab networks (Quest, LabCorp affiliates), urgent care chains, or cardiology practices — whichever fits your career goals.
