CBC - ANSWER Complete Blood Test; measures WBC, RBC, HGB, HCT,
PLT, MCV, MCH, MCHC, & RDW
WBC - ANSWER White Blood Cells; Attack & destroy microorganisms,
protect body against infection, react against foreign bodies or tissues; Increased
WBC count indicates an infection
WBC Normal Values - ANSWER Adult & Child >2 years: 5,000-10,000 /
mm^3
Child less than or equal to 2 years: 6200-17,000 / mm^3
Newborn: 9000-30,000 / mm^3
Differential WBC - ANSWER Neutrophils: 55-75%
Lymphocytes: 20-40%
Monocytes: 2-8%
Eosinophils: 1-4%
Basophils: 0.5-1%
Neutrophils - ANSWER Phagocytosis; kills and digests bacteria
Lymphocytes - ANSWER Tactically fight chronic bacterial infection and acute
bacterial infections; have T and B cells; T cells mature in thymus and are
involved in cellular immunity; B cells mature in bone marrow and involved in
humoral immunity and antibody protection
, Monocytes - ANSWER Phagocytic cells that can fight bacteria similar to the
way neutrophils do
Eosinophils - ANSWER Involved in allergic reactions; phagocytosis of antigen-
antibody complexes
Basophils - ANSWER Involved in allergic reaction
RBC - ANSWER Red Blood Cells; count of number of circulating RBCs in
1mm^3 of venous blood; within each RBC is hemoglobin that transports &
exchanges oxygen to the tissues & CO2 from the tissues; live for 120 days
RBC Normal Values - ANSWER Male: 4.7-6.1 million cells/mcL
Female: 4.2-5.4 million cells/mcL
Child: 3.8-5.3 million cells/mcL
Newborn: 4.8-7.1 million cells/mcL
HGB - ANSWER Hemoglobin; measure of total amount of HGB in the blood;
serves as a vehicle for O2 & CO2 transport, the O2 carrying capacity of the
blood is determined by the HGB concentration; it also acts as an important acid-
base buffer system
HGB Normal Values - ANSWER Male: 13-18 gm/dL
Female: 12-16 gm/dL
HCT - ANSWER Hematocrit; Measure of of the percentage of the total blood
volume that's made up by RBCs, height of RBC column is measured after
centrifugation; closely reflects HGB & RBC values
