HEMOGLOBIN

NORMAL VALUES DESCRIPTION CLINICAL SIGNIFICANCE

Males: 14- 18 g/dl Measure of total amount of Increased in polycythemia,

hemoglobin (Hgb) in peripheral dehydration, chronic obstructive

blood. lung disease; decrease in anemia

and after hemorrhage


4/6

HEMATOCRIT

NORMAL VALUES DESCRIPTION CLINICAL SIGNIFICANCE

Male: 42% - 52% Measure the percentage of the Increased w/ severe burns,

Females: 37% - 47% total blood volume that is made shock, severe dehydration,up by the RBCs and polycythemia;

decreased w/ severe blood

loss, leukemia and anemia


5/6

Iron (Fe)

NORMAL VALUES

Men: 65 to 176

g/dL

Women: 50 to 170

g/dL

DESCRIPTION

Iron contained in blood

serum (or plasma) is

normally bound to the

protein transferrin. Each

molecule of transferrin cantransport two molecules of

iron to areas of the body

that need this element

CLINICAL SIGNIFICANCEIncreased in:

Hemochromatosis,

hemosiderosis (eg, multiple

transfusions, excess iron

administration), hemolytic

anemia, pernicious anemia,aplastic or hypoplastic

anemia, viral hepatitis, lead

poisoning, thalassemia.

Drugs: dextran, estrogens,

ethanol, oral contraceptives.

Female: 4.2-5-4 million/mm3

DESCRIPTION

Actual cell count

CLINICAL SIGNIFICANCE

Increased in dehydration, w/

polycythemia, at high

altitudes, and w/ hypoxia;

decreased in anemia, leukemia
