Provider-performed microscopy.

Point-of-care testing (POCT) is defined as analytic testing performed outside the central laboratory using a device or devices that can be easily transported to the vicinity of the patient. This article discusses rules and regulations concerning POCT, especially those covering provider-performed microscopy (PPM). Types of PPM are also covered, including the fern test, tests for the presence on fecal leukocytes and pinworms, and examinations of urine sediment and seminal fluid. The coordination of PPM within a hospital is also covered.
