RBC
Red blood cells carry oxygen from your lungs to the rest of your body. Abnormal may be a sign of anemia, dehydration, bleeding, or another disorder. Women are lower. Male= 4.7- 6.1 Female= 4.2 - 5.4
Hemoglobin
Iron-Rich protein in RBCs that carries oxygen. May be a sign of anemia, sickle cell anemia, thalassemia. Main component of RBC. Male= 14-18 g/dlFemale= 12- 16g/dl
Hematocrit
Measures the percentage of RBCs found in whole blood. High levels- dehydration or anemia. Abnormal levels may be a sign of blood or bone marrow disorder. Male= 42- 52%Female= 37- 47%
RDW
Red cell distribution width. Calculation of the variation in the size of your RBCs. Normal value 11- 14.5%.
WBC
Part of the immune system: fights infections and disease. Normal values: 5,000- 10,000/ cmm
5 types of WBC's
Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils.
Neutrophil
55-70%. Produced in 7-14 days. Only exsist for 6 days. Primary defense against bacterial infection.
Lymphocytes
20-40%. Primary component of body's immune system. T cells- cellular immune reactionsB cells- Humoral immunity.
Monocytes
2-8%. Like the neutrophil. Produced more quickly and spend longer time in circulation than neutrophil.
Eosinophil
1-4%. Protect the body. Participate in engulfing and killing bacteria and other microorganisms such as parasites. Also acumulate in excess numbers.
Basophil
Mast cell. Capable of ingesting foreign particles and produce heprin and histamine. Often associated with asthma and allergies.
Platelet Count
Plays vital role in clotting. With decreased, at risk for bleeding. With increased, may have iron deficiency or malignancy. 150,000- 400,000/microliter.
Sodium
Needed to transmit electrical signals. Normal 136- 145 mEq/ L. Critical if <120 or >160
Potassium
3.5- 5 mEq/L. Regulate how heart beats. Muscle weakness.
