Laboratory Techniques Employed in Blood Analysis
Full Blood Count is a test used to evaluate the composition and concentration of the cellular components of blood such as red blood cells, white blood cells, platelets, etc. The abnormality it could identify are anaemia which means that there are less red blood cells or less haemoglobin in red blood cells than normal; polycythaemia which means there are too many red blood cells due to various causes; leucopoenia which means there are too few white cells due to various causes; leucocytosis which means there are too many white blood cells; thrombocytopenia which means there are too few platelets and thromnocythaemia which means there are too many platelets due to a disorders which affect cells in bone marrow which make the platelets.
Blood Clotting Tests are tests which are used to diagnose and assess bleeding problems and to monitor people who take anticoagulant medicines. The abnormality it could identify are either excessive bleeding or a risk of clotting inside the blood vessels (thrombosis) which are caused by the increase of tendency to coagulation including decreased physical activity, major surgery, oral contraceptive use, hormone replacement therapy, pregnancy and obesity.
Blood Chemistry Test is usually performed before and after a surgery to examine the general health of a patient and measures important chemicals produced and needed in the body. Different abnormalities it could identify such as liver diseases which is caused by excessive alcohol consumption that causes enzymes levels to increase; kidney diseases; pancreatic diseases, etc.

Several components of the blood can be separated and used in emergency as blood products for transfusion. These separated blood components are called blood products. A. Name four blood products.
Red blood cells
White blood cells
Plasma
Platelets B. Explain how and when three of these blood products could be used in transfusion.
Red Blood Cells
Red blood cell transfusion is needed if a person has too few or not
