Interpreting Lab Results

[TwinkieThirty1]

I recently went to the doctor because I have had some issues with weight gain 20lbs. in a year, being extreemly cold, mood changes and circulation problems like bluish tinted hands and upper thigh, and I have a goiter.  I work out regularly at least 3 times a week sometimes 5. My doctor ran some lab tests such as blood work, and an ultrasound and told me my results were positive.  She then had me scheduled for a thyroid uptake scan, but due to cost it would be $5000 out of pocket before insurance could cover.  I requested my lab results, could you please help me interpret my test results?  


          My Results      Range
Calcium  9.9 mg/dL      8.9-10.5
AST        21 U/L           14-42
ALT         24 U/L           9-52
Anion      19.6               5.0-17.0
TSH        2.36 uIU/mL    0.40-4.0
FT4         1.29 ng/dL     .74-1.55
FT3         3.2pg/mL       1.8-4.2

UltraSound Results

The right lobe measures 4.4 x 1.8 x 1.3cm.  There is a 0.3 x 0.2 x 0.3 cm hypoechoic nodule in its misportion.
The left lobe measures 4.9 x 1.5 x 1.5 cm.  No nodule is seen.
The isthmus measures 0.4cm.
Glandular echotexture is mildly heterogeneous.

Please help, I need to know what is going on with my body and will see if I need a new doctor.

You don't need a nuclear scan.
Thyroid function is currently normal, there is no signficant nodule.
The heterogeneous gland may mean Hashimoto's - would consider TPO antibody testing.

hi doc,
appreciate if you could tell me if levothyroxine(Euthryox) and generic levothryoxine sodium (thyronorm) are the same.

cheers
