Аннотация
Serum thyroid stimulating hormone (TSH) was measured using a highly sensitive enzyme-amplified immunoassay in 37 clinically euthyroid patients receiving thyroxine replacement therapy and compared with other biochemical tests of thyroid function. A highly significant correlation (P less than 0.001) was found between the basal serum TSH and the increase in serum TSH concentration 20 min after the administration of thyrotropin releasing hormone (TRH). The basal serum TSH was negatively correlated with the serum total thyroxine (P = 0.05). When patients results were classified as abnormal or normal many discrepancies were noted between the various thyroid tests. A suppressed serum TSH was found in 65% of patients with a normal serum total thyroxine. However, in patients on thyroxine replacement therapy a basal TSH measured by enzyme-amplified immunoassay provides the same information as a TRH test.
