Re: New labs - interpretation needed

[Guest guest]

Hi ,

It's normal to see a change in 4-5 weeks after an ATD change. You likely were

headed toward hypo on the dose that you were on. The recommended reference

range for TSH is 0.3-3.04, and TSH rises before thyroid hormone levels become

abnormally low. If you still have hypo symptoms you could probably manage

another ATD dose. Take care, Elaine

When it comes to TSH levels, I've found that _anything_ seems possible. I've

had mine drop from 1.4 to 0.78 in 10 DAYS. I'd say it's certainly possible

to drop that much in 5 weeks. Also, remember that TSH lags about 6 weeks

behind the T3 and T4. So the TSH you're looking at is really where you were

6 weeks ago. And small changes in FT4 causes much larger changes in values

for TSH (does that make sense?) I went back and looked for your last labs

and I believe your last FT4 was 1.1. You went up a little bit in FT4 (not a

significant change) so it seems reasonable that there has been a

corresponding dip in TSH.

You're moving up from a lower end level, so it doesn't appear you're going

hypo. Did your doctor make a dosage change based on the labs in May? If so,

these new values may be reflecting that dosage change. How are you feeling?

Do you feel better than you did in May?
