Which test is NOT typically included in the workup for amenorrhea?

In the context of evaluating a patient for amenorrhea, a CT scan of the abdomen is not typically included in the standard workup. The standard evaluation usually focuses on assessing hormonal levels and the possibility of pregnancy first.

A pregnancy test, such as hCG, is crucial because one of the primary concerns in amenorrhea is whether the patient is pregnant, as this can significantly influence further diagnostic steps.

Serum prolactin levels are also important to measure, particularly in cases where hormonal imbalances could be causing the amenorrhea. Elevated prolactin can indicate conditions like prolactinoma or hypothyroidism, both of which could be affecting menstrual cycles.

Thyroid-stimulating hormone (TSH) levels are typically measured as part of the workup because thyroid disorders are common causes of amenorrhea. Hypothyroidism can lead to menstrual irregularities, including amenorrhea.

In contrast, a CT scan of the abdomen is not routinely indicated in the initial evaluation of amenorrhea, as the most common causes can be identified through hormonal testing and a thorough clinical history. Imaging studies, including CT, may be reserved for specific scenarios where there is suspicion of anatomical abnormalities or tumors after other tests have suggested such conditions
