Borderline TSH and normal T3 and T4

I have borderline 5.5 TSh and normal T3 and T4, should I worry being Hypo

You are above the reference range for TSH, the t3 and t4 tests I am not familiar with as they are not labled as free or total levels, but as they are both in the lower end of the ranges, i would bet that with your levels along with symptoms of hypothyroidism, you would definitely benefit with thyroid hormone replacement.  Your doctor would be the best person to talk to about the dosage.

Hi,

Here are the Lab findings for T3, T4 and TSH

T3-CLIA-: 2.82 , ref range -: 1.08-4.014 nmol/L
T4-CLIA -: 99.00 ref range -: 59-135 nmol/L
TSH -CLIA -5.12 ref range -: 0.40 -4.20 uiU/ml

The test were conducted in the morning empty stomach (while fasting).

I have been trying to loose weight since 3-4 months, have been gyming 4-5 days in a week, moderate diet, however I have only lost 1-2 Kg
Please suggest

Just as a reference, TSH range is now recognized as being .3-3.0 for most places.  It can Vary by lab, but a TSH is probably indicitive of a thyroid problem if your free t4 and free t3 are low as well.

Please post whatever thyroid labs you've had done, along with the reference ranges, as these vary from lab to lab, so must come from your own report.  

At 5.5, your TSH is considered over range, but as ACNSC said, TSH is a pituitary hormone and should not be used to diagnose thyroid issues.

Most will tell you that TSH is ~not~ a good indication of thyroid issues (TSH is pituitary gland hormone that is sent to stimulate the thyroid production). We also need lab ranges, because each lab can have different ranges, and ~free~ T's is what you are wanting to have tested. From what I've learned so far, the higher the TSH, the more the thyroid ~needs~ to produce, but each person (like the labs) are different. Do you have any symptoms?
