In a laboratory workflow, what is reflex testing?

Reflex testing is when the lab automatically performs an additional test based on the result of an initial assay, using the same specimen and predefined rules. This built-in step helps gather more clinically useful information without waiting for a separate order. For example, if a TSH result is abnormal, the lab may automatically run an FT4 test to clarify thyroid status. This speeds up diagnosis, reduces the need for patient recalls, and ensures follow-up data are available promptly. It is not simply repeating the same test, a manual verification by a technologist, or a quality control procedure.
