[Screening of thyroid function proper by calculating the integral index based on data from in vitro...

A total of 1494 patients were investigated: 803--with the euthyroid state and extrathyroid (nonthyroid) pathology, 493--with primary hyperthyroidism and 101--with primary hypothyroidism; 93 healthy donors (61 women and 32 men) were entered into the control group. The thyroid integral index (II) was used for the assessment of the level of function of the thyroid proper. Normal II values ranged within 0.6-5 rel. units hypothyroidism values were within 0.6 and below this value, hyperthyroidism values--within 5 and above tris value. II calculation made it possible to divide (with 100% accuracy) the patients into 3 groups of the thyroid state: eu-, hypo- and hyperthyroidism. Euthyroidism values by the TSH level were within 1.7-9 mU/l.
