What is the normal range for T4 blood test?
Answered by 1 Apollo Doctors
The T4 blood test measures the level of thyroxine, a hormone produced by the thyroid gland, which plays a vital role in metabolism, energy regulation, and overall bodily functions. The T4 normal range for adults typically falls between 5.0 to 12.0 micrograms per deciliter (mcg/dL) for total T4 and 0.8 to 2.8 nanograms per deciliter (ng/dL) for free T4. Abnormal T4 levels can indicate thyroid disorders. Higher levels may suggest hyperthyroidism (overactive thyroid), while lower levels may point to hypothyroidism (underactive thyroid). The thyroid T4 normal range is an essential parameter for diagnosing and managing thyroid-related conditions.

I am suffering from erectile dysfunction (ED) and hypothyroidism, for which I am taking Thyronorm 50 mcg. I regularly go to the gym, follow a nutritious diet, and take whey protein (Livo Universal). Recently, I had a blood test, and the results showed TSH 5, globulin 3.8, RA factor active, low vitamin B12 and B9 levels, and high LDL. Please explain what these results mean.
