As the name indicates, these blood tests give the complete count of the various
types of blood cells namely white blood cells, red blood cells, and platelets counts.
• Usually, a good count of WBC ranges between 4300 and 10800 cells per cubic millimetre,
for RBC is 4.2 to 5.9 million cells per cubic mm and platelet count is 150000 to 400000
per cubic mm.
• Apart from the general routine health exam it can be used to detect various health
conditions like abnormal bleeding, infection or anaemia and much more.

3. Fibrinogen
Liver makes a blood plasma protein known as Fibrinogen or Factor I which is one of
the 13 coagulation factors that are responsible for blood clotting.

• When you have abnormal bleeding, this test may be recommended by your doctor.
Haemorrhage, abnormal fibrinolysis or inherited fibrinogen deficiency all some of the
causes of abnormal bleeding.

adenosine is Homocysteine.
• The normal range of Homocysteine is 4-15 µml/L.
• These tests can be recommended by the doctor in a few rare cases like onset of blood
clot formation, strokes, atherosclerosis or heart attack.
