A member asked:

Blood test tsh 3.40--considered "high" per lab . has reference range changed lately? free t4 .9 (normal range) have thyroid nodule, prolactinoma

A doctor has provided 1 answer

That TSH: While technically normal is considered by many to be slightly high relative to your age. Discuss it with your rotor. Hypothyroidism can increase prolactin somewhat. If you're taking cabergoline, it needs to be taken twice a week to be effective.
