An introduction to the basic indices of Blood CP for students of Medical Physiology.

1. Blood Complete Picture
By Abdullah Bin Khurram

2. 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

3. WBC Count
• Normal Range: 4,500
to 10,000 per
microliter
• Leucopenia – Less
WBCs
• Leucocytosis – More
WBCs

4. RBC Count
• Normal Range:
– In Males: 5.2 million
per mm3
– in Females: 4.7 million
per mm3
• Polycythemia
• Anemia

5. 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

6. Hematocrit
• Also Packed Cell
Volume (PCV)
• It is the percentage of
cells in blood
• Normal Range
– Males: 45%
– Females: 40%
– Newborn: 54%

7. 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%

8. Mean Corpuscular Volume (MCV)
• It is a measure of the
average red blood cell
volume (i.e. size)
• Normal Value:
90 μm3

9. Mean Corpuscular Haemoglobin
(MCH)
• The MCH is the
average amount of
hemoglobin in each
RBC.
• Normal Value:
30 pg

10. 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%

11. Platelets Count (PLT)
• Also Thrombocyte
Count
• Normal Range:
150,000 to 450,000
platelets per microliter
of blood
