Hello my friends,
As many of you know, 3 weeks ago I had my labs done and my FT4 was at the very bottom of the normal range and my other labs were ok. Well I redid the labs, and added a few as well. Please provide your feedback. All labs were taken while fasting and early in the morning.
Here are the prior labs: 2/10/17
T3, Free: 3.0 (2.3 - 4.2 pg/mL)
T4, Free 0.6: (0.6 - 1.4 ng/dl)
T4 TOTAL: 6.2 (5.5 - 11.8 mcg/dL)
TSH: 1.145 (0.200 - 4.500 UIU/ML)
Here are the latest lab test
Latest Labs: 3/3/17
T3, Free: 3.3 (2.3 - 4.2 pg/mL)
T3 Total: 110 (62 - 194 NG/DL)
FREE T4: 0.7 (0.6 - 1.4 NG/DL)
TSH: 1.056 (0.200 - 4.500 UIU/ML)
As you can see they did not order the T4 and she would not order any anti-bodies test, so I went ahead and ordered my own labs and had them done ~15 minutes prior to the above.
T4,Free: 1.01 (0.82 - 1.77ng/dL) See Above FT4
T3, Free 3.2 (2.0 - 4.4pg/mL)
Thyroglobulin Antibody: <1.0 (0.0 - 0.9IU/mL)
Thyroxine Binding Globulin: 17 (13 - 39ug/mL)
Thyroid Peroxidase (TPO) Ab: 9 (0 - 34IU/mL)
Why would my FT4 change so much in a 15 minute timeframe? Should I take them again to verify? The lab my dr uses also messed up my TSH a few months ago, so I am not sure which lab to believe.
