A thyroid function test is a simple blood test

Go and have a thyroid function test done if you are experiencing the symptoms of depression, anxiety or panic attacks.

You could save yourself years of heartache!

Have a quick look at this article about thyroid function tests, and then come back here.

And don't allow yourself to be "brushed off" by your doctor - persist and ask for further thyroid function tests if any of your results are in the ranges for discussed in this link.

Here are the current "normal ranges" - which may vary slightly from lab to lab:
Test Abbreviation Typical Ranges
Serum thyroxine T4 2 4.6-12 ug/dl
Free thyroxine fraction FT4F 0.03-0.005%
Free Thyroxine FT4 0.7-1.9 ng/dl
Thyroid hormone binding ratio THBR 0.9-1.1
Free Thyroxine index FT4I 4-11
Serum Triiodothyronine T3 80-180 ng/dl
Free Triiodothyronine 1 FT3 230-619 pg/d
Free T3 Index FT3I 80-180
Radioactive iodine uptake RAIU 10-30%
Serum thyrotropin TSH 0.3-3.0 uU/ml
Thyroxine-binding globulin TBG 12-20 ug/dl T4 +1.8 ugm
TRH stimulation test Peak TSH 9-30 uIU/ml at 20-30 min
Serum thyroglobulinl Tg 0-30 ng/m
Thyroid microsomal antibody titer TMAb Varies with method
Thyroglobulin antibody titer TgAb Varies with method

In summary: Your symptoms of depression, bipolar disorder, anxiety and panic attacks, MAY VERY WELL BE the result of an overactve or underactive thyroid gland.

Do not overlook the possibility. Have that thyroid function test

Avoiding the years of enduring the pain of any depressive illness is certainly worth the effort of doing this simple blood test, and then following up closely on the results
- and querying the doctor's findings if they do not fit with the information you find on these pages and it's very important links to "what the doctors are missing".

If necessary, print the article and give it to your doctor.
