Question 2 of 16

The laboratory diagnostic test of choice to confirm thyroid storm is:

Serum T3 and T4 levels.

Radionuclide thyroid scan.

TSH level.

TRH stimulation test.

None of the above.

Thyroid storm is usually due to inadequate treatment of hyperthyroidism. It is often precipitated by stress, and the disorder may be clinically difficult to differentiate from sepsis or transfusion reactions. Symptoms include fever, delirium, seizures, tachycardia, vomiting, and diarrhea. Although the serum levels of T3 and T4 are elevated in hyperthyroidism, thyroid storm is a clinical diagnosis.
