Low TSH

I am finally seeing an Endocrinologist in 2 weeks due to my TSH level lowering more and more ech time I have blood work done. The first time I had blood work my TSH level was 0.12 and was suppose to be ing the ranges of 0.40-4.50. The second time I just had it done it is now at 0.09 within the same ranges. The rest of my blood work was in normal ranges.

T4,total 9.3 Ranges 4.5-12.0
T3 uptake 25.7 ranges 22.0-35.0
Thyroglobulin < 20 Ranges <20
Thyroid Peroxidase AB <10 Ranges <35

So what does this mean? would I be considered Hypo or Hyper?

Also my temper and anxiety have been horrible too and I also had a baby 9 months ago so they said I might have postpartum thyroiditis.

No, I'm not saying your vitamin D is low because of your thyroid hormone.  Adequate vitamin D levels are necessary for your thyroid to make hormones and for those hormones to be able to get into cells.  So, if D is low, you can feel hypo even if there's nothing wrong with your thyroid because you have to have D to make thyroid hormone work.  Also, symptoms of D deficiency can be mimic hypo symptoms.

Your FT4 is actually at 41% of range, and 50% is the guideline.  So, it's a little on the low (hypo) side, but it's nothing to be concerned about.

I'd suggest you repeat FT4 and TSH and make sure they add in FT3.  If FT3 looks good (it should be in the top half of the range), I'd work on increasing your vitamin D and see if that alleviates your symptoms.

Is that FT4 or FT3?  The range doesn't really look right for FT4.

Your primary doctor should be able to handle the D deficiency, but your endo may not be averse to doing it.  D should be in the 50-70 range for proper metabolism of thyroid hormones.  Once again, your primary should address high triglycerides.

I just want to make sure that's FT4 before I comment further.

Do you have increased or decreased HR or BP?  Are you fatigued despite a full night's sleep, or are you fatigued due to insomnia?  Dry skin or acne?  Constipation or diarrhea?  

Are you taking thyroid meds?

I did not eat anything before the test. My HDL was 44 and was suppose to be > or 46 so thats not that bad. and from the test I just read that my TSH level dropped from 0.33 to 0.15 to 0.09, each month that's what it did. By now its probably at 0. I do have symptoms but not sure which it would be either HYPO or HYPER. I am fatigued, have hair loss, gained a whole lot of weight that I can not lose, I'm very weak and my muscle and joints are constantly hurting. And who should I talk to about the Vitamin D just my primary or my Endo Specialist, also with the triglyceride being so high why didn't my doctor mention anything about it? Who should I bring that up to? I'm gonna take all my blood work to Endo appointment so my doctor can look it over, because there is a lot of stuff going on!

The two tests that you had done, total T4 and T3 uptake are both considered obsolete and of little value.  Furthermore, they both measure the same thing.  Despite its name, T3 uptake is actually an indirect measure of T4.  Your doctor should be ordering FREE T3 and FREE T4.

That being said, your TT4 is a little high, but nothing to be concerned about.

Is that thyroglobulin or thyroglobulin antibodies?  They're two different tests.  Assuming they're antibodies, both TGab and TPOab are negative, indicating you probably don't have Hashimoto's thyroiditis, which is autoimmune hypothyroidism.  With Hashi's, TSH is usually high, although it can be low in early stages.

If hyperthyroidism is suspected, your really should be tested for TSI (thyroid stimulating immunoglobulin), which is the antibody associated with Graves' disease.

TSH is very volatile.  The change from 0.12 to 0.09 is totally insignificant.

Vitamin D is dismal; you need to ask your doctor about supplementing.  Many doctors will prescribe around 50,000 IU per week of D with that kind of deficiency.  That's usually taken for a month or so, then the dose is lowered until you are on a maintenance dose.

How do you feel?  Do you have either hypo or hyper symptoms?

Had you eaten (or drunk) anything before your triglyceride test?  You said HDL was low?
