Incorrect choices:

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

Correct Answer is D

Explanation

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.

A. Severe allergic reactions B. Chronic inflammation C. Frequent and severe infections D. Autoimmune diseases

Correct Answer is C

Explanation

Explanation: The correct answer is c. Frequent and severe infections are common clinical manifestations of immunodeficiency disorders. The weakened immune system is unable to effectively defend against infections, leading to recurrent and severe infections.

Incorrect choices:

a. Severe allergic reactions are more characteristic of allergies or hypersensitivity disorders, not immunodeficiency disorders.

b. Chronic inflammation can be seen in various conditions, but it is not a specific clinical manifestation of immunodeficiency disorders.

d. Autoimmune diseases result from an overactive immune response attacking the body's own tissues, which is the opposite of immunodeficiency disorders where the immune system is weakened and unable to adequately protect against infections.
