Conclusions: Low serum thyroid hormone levels--T3, T4, and TSH --in COVID-19 ICU patients are associated with higher mortality and could possibly be used as a prognostic factor for mortality among COVID-19 ICU patients. Thyroid hormone levels should be a part in the ...
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 and 12 micrograms per deciliter (...
