TG and hematocrit: Due to the increased prevalence of HT (38–40), numerous studies have been conducted by researchers to address its etiology and treatment.HT occurs when the immune system produces autoantibodies that attack the thyroid gland and some thyroid follicular cells are destroyed, resulting in insufficient thyroid hormone secretion and compensatory proliferation of undamaged thyroid follicular cells to produce more thyroid in order to maintain the normal function of organism hormones.
