CBC for H&P

hemoglobin (Hgb)

amount of protein that carries O2 and CO2 in blood; an indirect RBC count

14-18 g/dL, 12-16 g/dL

normal Hbg levels for males and females

Hematocrit (Hct)

percent of total blood volume that is RBC; an indirect RBC count; roughly 3x Hgb

42-52%, 37-47%

normal Hct levels for males and females

RBC count

number of RBCs in peripheral blood

Mean Corpuscular volume (MCV)

Average RBC size

Red Blood Cell Distribution Width (RDW)

Variation in size of RBCs

normocytic

normal RBC size

microcytic

small RBC size

macrolytic

large RBC size

anisocytosis

lots of different size RBCs

Mean Corpuscular Hemoglobin (MCH)

Average amount/content of Hgb within RBC, showing weight

Mean Corpuscular Hemoglobin Concentration (MCHC)

Average concentration/percent of Hgb within a RBC indicating color

normochromic

normal RBC color

hypochromic

decreased RBC color, pale

Platelets

Needed for clotting and vascular integrity, counted per mm³ of blood

Thrombocytosis

too many platelets (>400,000 mm³)

Thrombocytopenia

too few platelets (<100,000 mm³) causing risk of spontaneous bleeding

WBC Count

total number of WBCs in 1mm³ peripheral venous blood, average is 5,000-10,000 mm³

Leukocytosis

increased WBC (>10,000 mm³)

Leukopenia

decreased WBC (<4,000 mm³)

Differential

Added to CBC to measure % of leukocyte type

Neutrophils

57-67% of WBC

Neutrophils

WBC with a multi-lobed nucleus, red pale or blue granules, and deals with ongoing bacterial infections (slower creation and short life span) via mostly phagocytosis

bandemia

increased number of bands released by bone marrow because of urgent need like sepsis

bands

immature versions of neutrohils

Monocytes

3-7%

Monocytes

WBCs with kidney-shaped nucleus and no granules (faintly blue cytoplasm) that deals with bacteria faster and for longer-term

Eosinophils

1-3%

Eosinophils

WBCs with bi-lobed nucleus and dark pink granules that signals an allergic reaction, parasitic infection, or connective tissue disease; fight via phagocytosis of antigen-antibody complexes

Eosinophilia

increased eosinophil count about 3%

Basophils

0-1%

Basophils

WBCs with bi-lobed nucleus and dark purple granules that signals an allergic reaction, parasitic infection, or connective tissue disease; fight via phagocytosis of antigen-antibody complexes

Lymphocytes

23-33%

lymphocytes

WBCs with large spherical nucleus and no granules (faintly blue cytoplasm) that signals a chronic bacterial infection or acute viral infection; has two subtypes that are reported together in one percent count

T cells

A lymphocyte subtype that deals with cell mediated immunity and matures in the thymus

B cells

A lymphocyte subtype that deals with humoral immunity via antibody production and matures in the bone marrow

NLMEB

60-30-6-3-1
