Who can administer, read (measure), and interpret TB skin testing?
Persons whose healthcare license/certificate allows them to administer intradermal medications within their scope of practice may administer a TB skin test and read (measure) induration. Healthcare license/certificates which allow administration and reading of a TB skin test include:
- Certified Medical Assistants (MA-C)
- Licensed Practical Nurse (LPN)
- Registered Nurse (RN)
- Advanced Registered Nurse Practitioner (ARNP)
- Physician Assistant (PA)
- Medical Doctor (MD)
Interpreting a TB skin test requires reviewing the patient’s risk factors and millimeters of induration. Using this information, the health care provider determines if the TB test result is positive or negative. The scope of practice for MA-Cs does NOT allow them to interpret a TB skin test result. ARNPs, PAs, and MDs are the only health care providers who can diagnose a patient with TB infection or disease.
