Lab Results

[awolever]

So, I have been having issues for several months. Went to my gynecologist because my cycles being messed up is the worst part. They checked my thyroid. TSH was on the low end of normal. Free T4 was flagged low. She wants me to see my primary to discuss results. I’m wondering what to expect. Do these labs indicate a need for medication? Thank you!

Do you know the exact result(s) of the TSH and Free T4, along with reference ranges?  

Typically, if TSH is low, Free T4 would be high but when both are low, we have to suspect Central, or Secondary, hypothyroidism.  This happens when the thyroid is working okay, but there's a problem with the pituitary gland not producing enough TSH to encourage the thyroid to produce adequate hormones.   Many doctors miss Central hypothyroidism because they only concentrate on TSH and if it's "in range", they think everything is fine.  

The bottom line is that hypothyroidism is hypothyroidism and needs to be treated, no matter what the cause.

It will be more helpful once you post actual results with reference ranges.

Yes! Free T4 was .07 and the range given is 0.76-1.46. TSH was 1.43 and the range is 0.360-3.740.
