Question

1. What differences can you observe between the normal and diseased blood types?

2. When observing a blood smear, how can you differentiate between neutrophils and monocytes?

Answer 1

1.Research has shown that there is correlation between blood types and health. There are four blood types- A, B, AB and O depending upon antigens present. A has A antigen, B has B antigen, AB has both,O has no antigen. O is the universal donor and is the most common blood type and AB is the rarest one . People with A, B and AB are most susceptible to coronary heart disease as compared to O blood type.People with blood type AB are at most risk of blood clotting diseases and developing learning and memory issues ,suffer from dementia, various types of cancer and heart disease.A and B are prone to cancer and heart disease.

2. Different cell types in blood smear can be identified by staining with cytochemical dyes.Wright-Geimsa stain with its combination of different acidic and basic dyes differentially stain the granules, cytoplasm and nuclei of various blood cells.

For monocytes: cytoplasm is pale gray blue and nucleus deep bluish purple

For neutrophils: granules are stained purple to lilac color , cytoplasm is pink colored and nucleus is deep blue violet.
