Peripheral Blood film

August 6, 2022

A peripheral blood film (PBF) is the result of a laboratory workup that shows blood cells and other structures in the blood, which includes microscopically viewing blood cells smeared on a slide.

Keywords: Peripheral blood smear, Blood smear analysis, Blood cells morphology.

During the procedure, red and white blood cells and platelets are observed for the appearance, shape and count.

Complete blood count (CBC) is counting the number of  red blood cells, white blood cells, and platelets.

Complete blood count (CBC)

Red blood cells (RBC) / Erythrocytes: Men – 4.0 to 5.9 x 1012/L; Women – 3.8 to 5.2 x 1012/L

White Blood Cells (WBC) / Leukocytes: 4.5 to 11.0 × 109/L

Haemoglobin: Men – 130–180 g/L (13–18 g/dL); Women – 120–160 g/L (12–16 g/dL)

Hematocrit: Volume percentage of erythrocytes in blood. 41.5% to 50.4% for men; 35.9% to 44.6% for women. (Other names: packed cell volume (PCV), volume of packed red cells (VPRC), or erythrocyte volume fraction (EVF))

Mean Corpuscular Volume (MCV): Measurement of the average size of red blood cells.

Mean corpuscular Hemoglobin (MCH): Average amount of hemoglobin present in a single erythrocyte. 27-32 picograms (pg)/cell

Mean corpuscular Hemoglobin Concentration (MCHC): Average concentration of hemoglobin present in a single erythrocyte. 32% -36 %

Red Blood Cell Distribution Width (RDW):

Leukocyte Differential Count:

Platelet count:

Mean Platelet volume (MPV):
