Abnormal fall in total count of WBCs in the human blood is called:

• A. Anaemia
• B. Polycythemia
• C. Leucopenia
• D. Leukaemia

Answer 1

The correct option is C Leucopenia

Leucopenia is the decrease in WBCs (white blood cells) in the blood.

This increases the chances of infection in body. WBCs are involved in the immunity of body and destroy foreign pathogens and particles.

However, the number of WBCs may also decrease due to acute infection and this leads to weak immunity.

Leucopenia have further subtypes depending upon which type of leucocytes are decreasing.

There are five types of leucocytes in our body, basophils, eosinophils, neutrophils, lymphocytes and monocytes.

If there is decrease in count of neutrophils, the condition is known as neutropenia. Most often, leucopenia occurs due to fall in neutrophils cells.

So, the correct answer is 'Leucopenia'.
