How do I interpret my TSH results?
TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.
What should your TSH level be UK?
Reference range: TSH: 0.27 – 4.2 mU/L, Free T4 12 – 22 pmol/L, Free T3: 3.1 – 6.8 pmol/L.
What is a normal FT4 level UK?
FT4 normal values are 0.7 to 1.9ng/dL.
What should TFT levels be?
Normal range for an adult: 5.0 – 11.0 ug/dL (micrograms per deciliter of blood).
How do you interpret T3 T4 and TSH?
A low T3 value with a high TSH value is diagnostic evidence of low thyroid function….Comparing High/Low TSH and T3/T4 Levels
- A normal TSH and normal T4 show a normal thyroid.
- A low TSH and high T4 generally means an overactive thyroid.
- A high TSH and low T4 means an underactive thyroid.
What are normal TSH T3 and T4 levels?
Generally, healthy TSH levels are an indicator the whole system is working well, but that’s an oversimplification at best. A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter (ng/dL), while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter (μg/dL).
What is a normal TFT?
The term ‘thyroid function tests’ refers to the following investigations: TSH (0.4 – 4 mU/L) Free T4 (9 – 25 pmol/L) Free T3 (3.5 – 7.8 nmol/L)
What are TFT results?
The results of thyroid function tests (TFTs) must always be interpreted in light of the clinical status of the patient: hypothyroid, euthyroid or hyperthyroid. Awareness of the conditions and/or disorders that can be associated with different patterns of TFTs guides further investigation and management.
What are optimal T3 and T4 levels?
A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter (ng/dL), while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter (μg/dL). Free T4, which tests for the amount of T4 that is available in the body, should range between 0.8 to 1.8 nanograms per deciliter (ng/dL).
