complete blood count test
Red blood cells, which carry oxygen
White blood cells, which fight infection
Hemoglobin, the oxygen-carrying protein in red blood cells
Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in the blood
Platelets, which help with blood clotting
Red blood cells
The normal range:
for men, it is 5 million to 6 million cells/mcL
for women, it is 4 million to 5 million cells/mcL
comprise 45% of blood volume
round with a flattish, indented center, like doughnuts without a hole
Hemoglobin
The normal range:
for men is 14 to 17 grams per deciliter (gm/dL)
for women, it's 12 to 15 gm/dL
A protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the body and carries carbon dioxide back to the lungs.
For a low RBC count, symptoms could include
Fatigue
shortness of breath
dizziness, weakness, or lightheadedness, particularly when a person changes position quickly
increased heart rate
headaches
pale skin
For a high RBC count, symptoms such as:
fatigue
shortness of breath
joint pain
tenderness in the palms of the hands or soles of the feet
itching skin, particularly after a shower or bath
sleep disturbance
Hematocrit
blood test determines the percentage of red blood cells (RBC's) in the blood.
indicates the percentage of blood by volume that is composed of red blood cells.
"anemia" results from having too few red blood cells.
Hematocrit Range
For men, 38.8 to 50 percent
For women, 34.9 to 44.5 percent
For children ages 15 and younger, the normal range varies by age and sex.
