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
