I think a low trial dose of meds might be a good idea. Current TSH reference range according to AACE is 0.3-3.0. Your lab is using an obsolete range (most still do). So, according to TSH, you are hypo. Also, your FT4, while technically within range, is too low. The rule of thumb target for FT4 is mid-range (allowing for individual differences), and yours is in the lowest quarter. FT3 is in the middle third, which isn't too bad, but recommendation here is upper half to upper third. Since you know you have Hashi's and things are only going to deteriorate, why accumulate a bunch more symptoms before going on meds? Improving the levels of your thyroid hormones will also improve your metabolic system.
Here are the reference ranges used by the lab in parentheses along with my results.
PAI-1 levels (range 4-43) - 139 in Feb 2008, 87 in Nov 2009
T3 free(range 2.0-4.8) - 3.2
T3 Uptake(range 23.4-42.7) - 33.0
T4 (range 4.5-12.5) - 5.8
T4 free (range 0.8-1.7) - 1.0
T7 Index(range 1.2 - 4.3) - 1.9
TNF-Alpha (range 1.2-15.3) - 3.9 (feb 2008)
TSH (range 0.45-4.5) - 3.85 on 2/26/2008, and 4.44 on 11/25/2009 (one year later)
I had Hashimotos diagnosed when an Endo tested my Anti-Thyroid Antibodies in 2005. I have to dig the test out, but I do recall that it was not an incredibly high number like some folks. I THINK it was in the 700 range.
Symptoms? Lack of weight loss with exercise and low carb diet (consistent), dry, scaly scalp (i use T-gel shampoo on it), itchy legs (intermittent), fatigue (improves with exercise!), depression, noticably worse PMS irritability.
I look forward to hearing any opinions.
Please post the reference ranges on your labs...they're specific to your lab and have to come from your own lab report.
Do you have thyroid symptoms now?
Which tests were used to diagnose your Hashi's?
