Which of the following diagnostic tests is commonly used to assess immune function in individuals suspected of having an immunodeficiency disorder?

A.

Complete blood count (CBC)

B.

Chest X-ray

C.

Allergy skin testing

D.

Immunoglobulin levels

Answer and Explanation

The Correct Answer is D

Explanation: The correct answer is d. Immunoglobulin levels. Immunoglobulin levels, specifically IgG, IgM, and IgA, are commonly measured to assess immune function and identify deficiencies in immunoglobulin production. Abnormalities in immunoglobulin levels can indicate the presence of an immunodeficiency disorder.

Incorrect choices:

a. A complete blood count (CBC) provides information about various blood components, such as red blood cells, white blood cells, and platelets, but it does not specifically assess immune function.

b. A chest X-ray may be used to evaluate the condition of the lungs and detect infections, but it is not a specific test for immunodeficiency disorders.

c. Allergy skin testing is used to diagnose allergies and assess the body's response to allergens, but it is not a diagnostic test for immunodeficiency disorders.

Correct Answer is C

Explanation

Explanation: The correct answer is c. Primary immunodeficiency disorders are typically present at birth or during early childhood and are caused by genetic defects that affect the function of the immune system. They are not acquired later in life due to environmental factors.

Incorrect choices:

a. Primary immunodeficiency disorders are not acquired later in life; they are usually genetic and present from birth.

b. Primary immunodeficiency disorders are characterized by a weakened or deficient immune response, not an overactive immune response.

d. Primary immunodeficiency disorders are often not easily treatable with antibiotics and antiviral medications because they result from genetic defects in the immune system.

Correct Answer is D

Explanation

Explanation: The correct answer is d. Immunodeficiency disorders can be caused by medications or medical treatments. Immunodeficiency disorders are conditions in which the immune system is weakened or dysfunctional, leading to an increased susceptibility to infections. They can be primary (genetic) or secondary (acquired). Secondary immunodeficiency disorders can be caused by various factors, including medications (e.g., immunosuppressive drugs used after organ transplants), medical treatments (e.g., chemotherapy for cancer), and certain diseases (e.g., HIV/AIDS).

Incorrect choices:

a. Immunodeficiency disorders are characterized by a weakened immune system, not an overactive one. Overactive immune responses are seen in autoimmune disorders.

b. Immunodeficiency disorders can be both primary (genetic) and secondary (acquired) in nature. While some immunodeficiencies are genetic, others can be acquired later in life due to various factors.

c. Immunodeficiency disorders result in a decreased ability to fight infections, not an increased one. Individuals with immunodeficiencies are more susceptible to infections and may experience recurrent or severe infections.
