Hematocrit
of 40 means that 40% of the volume of blood consists of RBCs
A buffy coat layer
consists of WBC
thin, white layer
lies btwn the heavier RBC layer and the lighter, yellow plasma
The diagnosis of anemia indicates
lower than normal hematocrit
Polycythemia refers to
significant increase in RBCs
Why would the hemoglobin levels of an anemic patient be lower than the hemoglobin levels of a normal, healthy individual?
because hemoglobin resides in RBCs, you would anticipate a low hematocrit level to coincide with a low hemoglobin level
Anemia refers to
a lower-than normal hematocrit
To complete the blood test to measure hematocrit, you must seal the blood-containing capillary tubes on one end with a clay material so that
the blood sample can be centrifuged withut having the blood spray out of the tube
Possible causes of polycythemia include
living at high altitudes
You would expect anemia to develop in a person
who has abnormally shaped hemoglobin in their RBCs
Predict how the hematocrits of the patients living in Denver, Colorado ( approx. one mile above sea level), will compare with the hematocrit levels of the patients living in Boston, Massachusetts (at Sea level)
the hematocrit of the Denver residents will be lower than those of the Boston residents
Why would the hemoglobin levels of an anemic patient be lower than the hemoglobin levels of a normal, healthy individual?
becasue hemoglobin resides in RBCs, you would anticipate a low hematocrit level to coincide with a low hemoglobin level
