What is the significance of a low T3 (liothyronine) uptake with normal TSH and ft4 7 weeks post total thyroidectomy and on levothyroxine for 7 wks?
No significance: T3 (liothyronine) uptake is an old test used to indirectly measure t4. Now that we have assay to accurate measure free t4, we don't use this test anymore. If your TSH and free T4 is normal on levothyroxine, then you are doing fine on the current dose. No need to change anything at this point. ...Read moreSee 1 more doctor answer
Blood work- TSH 2.92, T4 9.1, T3 (liothyronine) uptake 31, free T3 (liothyronine) index 2.8, T4 free 1.28, r T3 (liothyronine) 27.5, T3 (liothyronine) 117 T3 (liothyronine) free 2.7
does this show hypothyroid?
No: Tsh is the most important test to evaluated the thyroid and it is normal. Free T4 gives the next best information and yours was in the normal range. ...Read more

Test done: thyroxine (t4) 12.4 range 4.5-12.4 T3 (liothyronine) uptake 33 range 24-39 TSH 0.01 range 0.450-4.500 . I am on levo 150mg last 60 days. What it means ?
Possible causes of high rbw, high segmented neutrophils, low lymphocytes, low basophils, and high thyroglobulin ab., high T3 (liothyronine) uptake and ferritin?
normal Total T4, T3 (liothyronine) Uptake, FTI, Ultrasensitive TSH
LOW Total T3 (liothyronine) (63.55 ng/dl)
Synthroid dose needs to increase?
It's OK: Hi. Your TSH is "normal", but I'd shoot for a value on therapy generally around the 1.0-1.5 range. The total T4, T3 (liothyronine) resin uptake, and FTI are prehistoric tests no one in the thyroid field has used for years. Your body regulates conversion of T4 to T3 (liothyronine), so your T3 (liothyronine) should be just what the body ordered. Your T3 (liothyronine) is close to the normal range; if you repeat it it's likely to be within normal range. ...Read more
Yes: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your results are normal.

I had a thyroid panel test and my results are below. Should I be taking medication?
TSH - 8.070
T4, Total - 5.4
T3 Uptake Ratio - 26
Repeat test: Ideally, thyroid panel tests should be evaluated based on the reference range for the laboratory where the tests are performed. Most commonly, the reference range for TSH = 0.5 - 5.5. Although your TSH may be slightly high, you may not need treatment. Your total and free T4 are normal. Results such as these usually warrant retesting in 1-3 months. TSH will often return to normal without treatment. ...Read more
Tsh level is 9.23 HIGH (0.450-4.500) Thyroxine T4 6.4 ( 4.5-12)
T3 uptake 27 (24-39%).
free thyroxine index 1.7
what does it mean?
Hypothyroidism : Your TSH is a substance made in the brain. When high it indicates the possibility that your thyroid gland is not able to make enough thyroid hormone. In some cases, it takes a repeat test to clarify this was not a false test, but at your age, and depending on how well or not you feel, it might indicate the need to start thyroid replacement treatment. Please review these tests with your doctor. ...Read more
