Diagnostic studies of Hyperprolactinemia
- ↑ PRL (✓ fasting levels), but elevated in many situations, ∴ r/o
- pregnancy or exogenous estrogens,
- hypothyroidism,
- dopamine agonists (eg, psych meds, antiemetics),
- renal failure (↓ clearance),
- cirrhosis,
- stress,
- ↑ carb diet.
- Watch for hook effect:
- assay artifact yielding falsely low PRL if very high serum PRL levels;
- retest with sample dilution.
- MRI brain pituitary protocol
