The Correct Answer is C

Explanation: The correct answer is c. Flow cytometry. Flow cytometry is a specialized test used to analyze the different cell types in a blood sample. In the case of SCID, flow cytometry can help identify the absence or severe deficiency of T cells and B cells, which are essential components of the immune system.

Incorrect choices:

a. A tuberculin skin test (TST) is used to detect exposure to tuberculosis (TB) and is not specific to diagnosing SCID.

b. A Western blot test is a type of immunoassay used to detect specific antibodies or antigens in the blood but is not specific to diagnosing SCID.

Correct Answer is B

Explanation

Explanation: The correct answer is b. X-linked agammaglobulinemia. X-linked agammaglobulinemia is a primary immunodeficiency disorder caused by a genetic mutation that leads to the absence of mature B cells, resulting in an inability to produce antibodies (immunoglobulins). As a result, individuals with this disorder are highly susceptible to infections, especially bacterial infections.

Incorrect choices:

a. DiGeorge syndrome is a primary immunodeficiency disorder characterized by abnormalities in the development of certain organs, including the thymus, leading to impaired T cell function.

c. Severe combined immunodeficiency (SCID) is a group of rare genetic disorders that affect both T cells and B cells, resulting in a severe impairment of the immune system.

d. Acquired immunodeficiency syndrome (AIDS) is a secondary immunodeficiency disorder caused by the human immunodeficiency virus (HIV) infection, which specifically targets and destroys CD4+ T cells, weakening the immune system's ability to fight infections.

A. Unexplained weight loss B. Recurrent skin rashes C. Chronic diarrhea D. Difficulty falling asleep

Correct Answer is C

Explanation

Explanation: The correct answer is c. Chronic diarrhea. Primary immunodeficiency disorders can affect the gastrointestinal system, leading to chronic diarrhea due to frequent infections and inflammation.

Incorrect choices:

a. Unexplained weight loss is not a specific symptom of primary immunodeficiency disorders. It may be seen in various other medical conditions, such as cancer or metabolic disorders.

b. Recurrent skin rashes are not a characteristic symptom of primary immunodeficiency disorders. Skin rashes may be caused by allergic reactions or dermatological conditions.

d. Difficulty falling asleep is not typically associated with primary immunodeficiency disorders. It may be related to sleep disorders or anxiety.
