Haemotology
Science of haematology deals with blood cells and related subjects.
It speaks of haemoglobin, RBC counts, WBC counts, size and structure of cells, platelets and abnormalities of them.
Haemoglobin: It is most important part of blood as it supplies Oxygen to all tissues of body. If for any reason somebody lacks proper haemoglobin level, which is called as anaemia, it causes serious problems such as breathlessness, swelling on body, paleness and even serious cardiac problems.
Deficiency of haemoglobin can be due to many reasons. Some are lack of proper diet, iron deficient diet, vitamin deficiencies and some hereditary causes.
WBCs are very important in defense mechanism of body. They try to kill the invaders and
keep body protected.
Increase
and decrease in counts of white blood cells speaks of some kind of infection.

P. falciparum
Morphological changes like presence of band forms or toxic granulation
speaks of septicemia

Leukamia( blood cancer) can be detected by performing WBC count and examining morphology microscopically.

Platelets are very important in mechanism of blood clotting. Reduced number of platelets in blood can cause serious problems like hemorrhages which can lead to paralysis or even death.
Blood cell counters increase ease and reliability of reporting abnormalities which effectively can reduce possibility of serious complications and can save lives.
