Title: [Diagnostic accuracy of FT3-RIA and FT4-RIA compared to total T3-RIA and total T4-RIA]. Author: Müller HW, Montz R, Schofer M. Journal: Nuklearmedizin; 1985 Feb; 24(1):44-7. PubMed ID: 4000980. Abstract: The values of FT3-serum concentration (Amerlex-RIA) from 311 patients and the FT4-values (Amerlex-RIA) from 745 patients were compared with the total T3- and total T4-values with regard to their diagnostic accuracy in hypo-, eu- and hyperthyroidism. The classification of patients into these three diagnostic categories was determined by the majority of available parameters. The analysis of the predictive values demonstrated that determination of free hormones usually guarantees a safe distinction between hypo-, eu- and hyperthyroidism. Taking into account prevalence, the determination of free hormones appears to be superior to that of total hormones.[Abstract] [Full Text] [Related] [New Search]
