Dialysis Technician
Also known as: Audiometrist, Brain Wave Technician, Central Supply Technician
Dialysis technicians operate life-sustaining kidney machines for patients with end-stage renal disease. You'll insert needles into access sites, monitor blood flow during four-hour treatments, and watch for medical emergencies that require immediate response.
Getting Started
How to Become a Dialysis Technician
You can start working as a dialysis technician in 2.1 years with $4k-$7k in training — that is faster than most certificate-level health care careers like ultrasound technician (27 months).

Overview
What Does a Dialysis Technician Do?
Dialysis technicians work in specialized clinics, hospital units, and home care settings where patients receive treatment three times per week. Your day splits between highly technical medical procedures — cannulation, machine operation, patient monitoring — and administrative duties like charting and equipment maintenance.
Requirements
Licensing & Certification
National certification helps but isn't required to work in most states — about 70% of employers prefer certified technicians and pay $2k-$4k more annually.
| Credential | Status | Cost | Renewal |
|---|---|---|---|
| CHT (BONENT) | Recommended | $250 | Every 4 yr |
| CCHT (NNCC) | Also accepted | $225 | Every 3 yr |
CHT (BONENT) (Board of Nephrology Examiners Nursing and Technology) — Demonstrates competency in hemodialysis patient care -- widely recognized by dialysis clinics nationwide
- Exam: 150 multiple-choice questions, approximately 3 hours (CBT format)
- Cost: $250 (computer-based testing)
- Renewal: Annual certification fee ($65) and adherence to recertification criteria
CCHT (NNCC) (Nephrology Nursing Certification Commission) — Alternative to CHT -- validates clinical hemodialysis skills and is equally accepted by employers
- Exam: 150 multiple-choice questions, approximately 3 hours
- Cost: $225
- Renewal: 30 contact hours of continuing education and 3,000 hours of work experience
California requires state certification through the Department of Public Health in addition to national credentials. New Mexico has similar state requirements. Most other states accept BONENT or NNCC certification without additional licensing.
No interstate compact exists for dialysis technicians. You will need a separate license in each state where you practice.
Compensation
Dialysis Technician Salary
At $44k, dialysis technicians earn less than ultrasound technicians ($89k) but more than EKG technicians ($67k). Pay varies significantly by region, with urban dialysis centers typically offering $5k-$8k more than rural facilities.
$44k/yr
median annual salary
You will spend $6k and 2.1 years to start earning $44k — that is 2 months to pay back your training. This fast payback beats most health care careers requiring similar education.
Salaries vary by location and setting. Dialysis Technicians in metropolitan areas and specialty practices typically earn more than the national median.

Will AI Replace Dialysis Technician?
AI cannot perform the core technical skills that define this role — inserting needles into vascular access sites, physically assessing patients for complications, and responding to medical emergencies during treatment. While modern dialysis machines have automated monitoring features, technicians still manually control all treatment parameters and make critical decisions about patient safety. No AI tools exist that can replace hands-on patient care in dialysis centers.
Dialysis machine monitoring has some automation but tech performs all cannulation, patient assessment, and emergency response.
