Question

If you suspect a major deficiency of antibodies in a person, which of the following would you look for confirmatory evidence?

• A. Serum globulins
• B. Fibrinogen in plasma
• C. Serum albumins
• D. Haemocytes

Answer 1

The correct option is A Serum globulins

An antibody is a protein molecule produced in the living body which specifically inactivates an antigen. Chemically, antibodies are globular proteins which form about 17-20% of the total protein in the blood serum. Antibodies belong to a class of serum proteins, which are called γ or gamma globulins. Thus, the antibodies are also known as immunoglobulins and are produced by the lymphocytes. Hence, to confirm the deficiency of antibodies in a person, serum globulins will be tested.

So, the correct answer is 'Serum globulins'.
