Q

What are the functions of eosinophils?

A

Destroy parasites and helps control inflammation and allergic reactions

23
Q

What are the functions of basophils?

A

Releases heparin (an anticoagulant) and histamine (a blood vessel dilator)

24
Q

What are the functions of monocytes?

A

Phagocytoses dead or living cells and micro organisms

25
Q

What are the functions of lymphocytes?

A

Provides immunity, produces antibodies, destroys foreign cells and infected cells with viruses.

26
Q

What are the functions of platelets?

A

Helps control blood loss from injured blood vessels needed for blood clotting.

27
Q

Why is a differential white blood cell count performed?

A

A differential white blood cell count is performed to determine the percentage of each of the various types of white blood cells present in a sample. This test is useful because the relative proportions of WBC may change in particular diseases.

28
Q

What is the normal range of neutrophils and hat do elevated counts potentially indicate?

A

54-62%. Bacterial infections, stress

29
Q

What is the normal range of lymphocytes and what do elevated levels potentially indicate?

A

25-33%. Mononucleosis, whooping cough, viral infections

30
Q

What is the normal level of monocytes and what does an elevated count potentially indicate?

A

3-9% Malaria, tuberculosis, fungal infections

31
Q

What is the normal level of eosinophils and what does an elevated level potentially indicate?

A

1-3% Allergic reactions, autoimmune diseases, parasitic worms.

32
Q

What is the normal levels of basophils and what does an elevated level potentially indicate?

A

Less then 1%. Cancers, chicken pox, hypothyroidism.
