Flow cytometry

Liver function tests

Answer and Explanation

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 C

Explanation

Explanation: The correct answer is c. Serum immunoglobulin levels. A primary immunodeficiency disorder often results in abnormal levels of immunoglobulins (antibodies) in the blood. Measuring serum immunoglobulin levels can help identify potential deficiencies and guide the diagnosis of primary immunodeficiency disorders.

Incorrect choices:

a. Enzyme-linked immunosorbent assay (ELISA) is a test used to detect specific antibodies or antigens in the blood, but it is not specific to diagnosing primary immunodeficiency disorders.

b. A chest X-ray is not a specific test for diagnosing primary immunodeficiency disorders. It is typically used to assess the condition of the lungs and chest organs.

d. A complete blood count (CBC) is a general blood test that may reveal abnormalities in white blood cell count but does not specifically assess immunoglobulin levels.

A. Recurrent ear infections B. Chronic fatigue and lethargy C. Failure to thrive D. Persistent joint pain

Correct Answer is C

Explanation

Explanation: The correct answer is c. Failure to thrive. SCID is a severe form of immunodeficiency that affects multiple components of the immune system, leading to recurrent and severe infections and failure to thrive in affected infants.

Incorrect choices:

a. Recurrent ear infections are more commonly seen in other types of immunodeficiency disorders, such as selective IgA deficiency.

b. Chronic fatigue and lethargy may be seen in various medical conditions but are not specific to SCID.

d. Persistent joint pain is not a characteristic symptom of SCID. It may be associated with other autoimmune or inflammatory conditions.
