Blood Complete Picture
By Abdullah Bin Khurram
Definition
It’s a laboratory technique which includes quantification of cellular components of
blood. It has Hb, Haematocrit, RBCcount, MCV, MCH, MCHC, total & differential
leukocyte count and Platelet count
WBC Count
• Normal Range: 4,500 to 10,000 per microliter
• Leucopenia – Less WBCs
• Leucocytosis – More WBCs
RBC Count
• Normal Range:– In Males: 5.2 million
per mm3
– in Females: 4.7 million per mm3
• Polycythemia• Anemia
Haemoglobin Concentration
• It is the mass of hemoglobin found per liter in body
• Normal Range– In Males: 16 g/dL– In Females: 14 g/dL
Hematocrit
• Also Packed Cell Volume (PCV)
• It is the percentage of cells in blood
• Normal Range– Males: 45%– Females: 40%– Newborn: 54%
RBC Distribution Width
• It is a measure of the variation of red blood cell (RBC) width
• Normal RBC diameter is 6-8μm
• Normal Range:
11% – 15%
Mean Corpuscular Volume (MCV)
• It is a measure of the average red blood cell volume (i.e. size)
• Normal Value:
90 μm3
Mean Corpuscular Haemoglobin (MCH)
• The MCH is the average amount of hemoglobin in each RBC.
• Normal Value:
30 pg
Mean Corpuscular Haemoglobin Concenteration (MCHC)
• It is a measure of the concentration of hemoglobin in a given volume of packed red blood cell.
• Normal value: 34%
Platelets Count (PLT)
• Also Thrombocyte Count
• Normal Range: 150,000 to 450,000 platelets per microliter of blood
