Chapter 24: Diagnostic Tests and Specimen Collection

Question 1

How are the terms hematocrit and anemia connected?

Answer 1

The hematocrit refers to the separation of blood and is the amount of blood cells in relation to the amount of plasma. It is decreased in severe anemias (low red blood cell count) and massive blood losses but is higher than normal in dehydration and shock.

Question 2

What is a biopsy?

Answer 2

Organs and tissues removed at biopsy (surgical excision of a small amount of tissue) are studied closely, and a pathology report is prepared. Studies of tissues and cells are performed to detect carcinogenic, metabolic, vascular, and other changes.
