Do normal-appearing adrenal glands on ultrasound require blood tests to determine proper function?
Yes, normal-appearing adrenal glands on imaging don't tell the full story about how well they're functioning. CAH is a condition where the adrenal glands may look structurally normal but don't produce hormones correctly due to enzyme deficiencies.
Blood tests are essential for diagnosing and monitoring CAH because they measure hormone levels like 17-OHP, androstenedione, testosterone, and cortisol. These tests show whether the adrenal glands are making the right amounts of hormones, which an ultrasound can't determine.
Even if adrenal glands appear normal on imaging, blood work can reveal:
- High levels of 17-OHP (indicating 21-hydroxylase enzyme isn't working properly)
- Elevated androgens
- Low cortisol levels
- Abnormal aldosterone levels
For anyone with CAH symptoms or a family history, blood tests and sometimes ACTH stimulation testing are necessary to assess adrenal function, regardless of how the glands look on imaging.
