Complete Blood Count (CBC) |
Panel of tests that evaluates 3 types of cells that circulate blood:
1) Eval of WBC: WBC count WBC differential
2) Eval of RBC: RBC count Hgb Hematocrit RBC indices Reticulocyte count
3) Eval of platelets Platelet count Mean platelet volume Platelet distribution width

RBC |
Newborn: 4.4-5.8 x 10^6/uL or 4.4-5.8 x 10^12/L (SI)
Adult male: 4.7-6.1 x 10^6/uL or 4.7-6.1x 10^12/L (SI)
Adult female: 4.2-5.4 x 10^6/uL or 4.2-5.4 x 10^12/L (SI) |
|
|
# of RBC/mm^3 |
(# cells x depth factor x diluting factor)/ (length of 2° square x width of 2° square x # of squares) = Rbc/mm^3 |
|
|
WBC |
Newborn: 9.0-30.0 x 10^3/uL or 9.0-30.0 x 10^9/L (SI)
Child/adult: 4.8-10.8 x 10^3/uL or 4.8-10.8 x 10^9/L (SI) |
|
|
# of WBC/mm^3 |
(# of cells x depth factor x diluting factor)/ (length of 1° sq x width of 1° sq x # of squares) =
(# of WBCs counted on 1 side x 10 x 100)/ (1.0 x 1.0 x 4) |
|
|
Platelets |
130-400 x 10^3/uL or 130-400 x 10^9/L (SI) |
|
|
# of platelets /mm^3 |
(# of platelets x depth factor x diluting factor)/ (length of 1° sq x width of 1° x # of squares) =
(# of platelets x 10 x 100)/ (1.0 x 1.0 x 1 |
|
|
Hematocrit (hct) |
Measures the percentage of a person's total blood volume that consists of RBCs Newborn: 53-66% Adult male: 42-52% Adult female: 37-47% |
|
|
Hemoglobin (hgb) |
Measures the total amount of the oxygen-carrying protein in the blood Newborn: 17-23 g/dL Adult male: 14-18 g/dL Adult female: 12-16 g/dL |
|
|
RBC indices |
Calculations that provide info on the physical characteristics of the RBCs
Includes 1) MCH 2) MCHC 3) MCV 4) RDW |
|
|
Mean corpuscular hemoglobin (MCH) |
Avg Hgb content of the RBC; Avg mass of Hgb per RBC in a sample of blood
MCH = (Hemoglobin x 10)/ RBC (in millions)
Normal MCH: 27-31 pg |
|
|
Mean corpuscular hemoglobin concentration (MCHC) |
Avg [hgb] per unit volume of RBCs; Concentration of Hgb in a given volume of packed RBCs
MCHC = (hemoglobin x 100)/ hematocrit
Normochromic: 32-36% Hypochromic: <32% |
|
|
Mean corpuscular volume (MCV) |
Avg volume of RBCs per liter ;Avg volume (size) of single RBC
MCV= (Hematocrit x 10)/ RBC (in millions)
Normocytic: 80-100 fL Microcytic: <80 fL Macrocyric: >100 fL |
|
|
Red blood cell distribution width (RDW) |
Coefficient of variation of the red cell volume distribution (variation in size of RBCs)
(Stdev of RBC Volume x 100)/ Mean MCV
Normal value= 11.5%-14.5% Elevated RDW indicates anisocytosis |
|
|
Mean platelet volume (MPV) |
Avg size of platelets Normal: 7.4-10.4 fL Increased in idiopathic thrombocytopenic purpura (ITP) |
|
|
Erythrocyte Sedimentation Rate (ESR) |
Male: 0-15 mm/hr Female: 0-20mm/hr |
