Hematocrit
A hematocrit test measures how much of the blood consists of red blood cells.
Why it matters: Red blood cells carry oxygen around the body, so the result helps identify conditions affecting red blood cell production or health. A low result is a sign of not having enough healthy red blood cells, which is anemia.
