What Is TSH Test?
To determine whether your thyroid gland is functioning properly, a TSH test is performed. It can inform you if it’s hyperthyroidism- or hypothyroidism- related (hypothyroidism). The test can also identify thyroid conditions even in the absence of symptoms.
An untreated thyroid condition might have negative effects on one’s health.
High TSH Levels
According to the American Thyroid Association, TSH levels normally range between 0.4 to 4.0 milliunits per litre (mU/L). The top limit often falls between 4 and 5. T3 T4 TSh test is done, however ranges will differ between laboratories. You may have an underactive thyroid if your level is higher than this.
Low TSH Levels
It’s also possible that the test results reflect an overactive thyroid and TSH levels that are lower than usual. This might be brought on by:
Graves’ illness, in which the thyroid is attacked by the body’s immunological system
Your body contains too much iodine Excessive doses of thyroid hormone therapy
Too much of a naturally occurring thyroid hormone supplement

Taking a synthetic thyroid hormone in pill form everyday is the typical course of treatment for an underactive thyroid. Your hormone levels will return to normal as a result of this treatment, and you might start to feel less tired and lose weight.
After two or three months, your doctor will check your TSH levels to make sure you’re receiving the proper medicine dosage. They will continue to evaluate your TSH level annually when they are certain you are taking the right amount to ensure it is normal.
