title: [Clinical value comparison between chemiluminescent immunoassay and immunoradiometric assay in detecting TSH in serum].
abstract: OBJECTIVE
  To compare the clinical value between chemiluminescent immunoassay (CLIA) and immunoradiometric assay (IRMA) in detecting TSH in patients with hyperthyroidism and hypothyroidism.
  
  
  METHODS
  The TSH levels in serums were detected by CLIA and IRMA in 112 normal persons, 120 hyperthyroidism patients and 58 hypothyroidism patients.
  
  
  RESULTS
  CLIA was significantly correlated with IRMA (r = 0.98, P < 0.01). CLIA had higher coincidence rate than IRMA in the diagnosis of hyperthyroidism and hypothyroidism, and CLIA was more accurate and repetitive than IRMA.
  
  
  CONCLUSIONS
  CLIA is more valuable than IRMA in diagnosing both hyperthyroidism and hypothyroidism.
