A Color Atlas of Urine Microscopy

Microscopic urinalysis was developed initially as an integral part of the physical examination of the patient. Its value lies in the fact that it is non-invasive, economical and frequently provides evidence of abnormalities before these are detectable by other means. Increasingly, however, the test has become separated from its clinical context and is frequently undertaken in the laboratories of one or another branch of pathology by scientists with minimal training and understanding.
