Answer: Red blood cells, which carry oxygen White blood cells, which fight infectionHemoglobin,
the
oxygen-carrying protein in red blood cellsHematocrit, the proportion of red blood cells to the fluid
component, or plasma, in the bloodPlatelets, which help with blood clotting
Q2
Red blood cells
Answer: The normal range:for men, it is 5 million to 6 million cells/mcLfor women, it is 4 million to
5 million
cells/mcLcomprise 45% of blood volumeround with a flattish, indented center, like doughnuts
without a
hole
Q3
Hemoglobin
Answer: The normal range:for men is 14 to 17 grams per deciliter (gm/dL) for women, it's 12 to 15
gm/dLA
protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the
bodyand
carries carbon dioxide back to the lungs
Q4
For a low RBC count, symptoms could include
Answer: Fatigueshortness of breathdizziness, weakness, or lightheadedness,particularly when a
person changes
position quicklyincreased heart rate headachespale skin
Q5
Hematocrit
Answer: 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
, Q6

Answer: For men, 38.8 to 50 percentFor women, 34.9 to 44.5 percentFor children ages 15 and
younger, the
normal range varies by age and sex
Q7
Hemoglobin Range
Answer: for men is 14 to 17 grams per deciliter (gm/dL) for women, it's 12 to 15 gm/dL
Q8
Low hematocrit indicates
Answer: An insufficient supply of healthy red blood cells (anemia)A large number of white blood
cells due to
long-term illness, infection or a white blood cell disorder such as leukemia or lymphomaVitamin
or
mineral deficiencies Recent or long-term blood loss
