Ciba Corning ACS:180 testosterone assay evaluated.
A fully automated direct assay of testosterone has been developed for the Ciba Corning ACS:180 immunoassay system. We have evaluated this method and compared specimen results with those from the Diagnostic Products Corp. (DPC) and Medgenix direct assays and an in-house extraction assay. Accuracy of the method was assessed by measuring GC-MS-targeted serum pools. Within-assay im- precision was <...
متن کاملHomogeneous nonisotopic assay for phenytoin evaluated.
We evaluated a new homogeneous immunoprecipitation assay for phenytoin in human serum. No sample dilution or pretreatment is required. The new method is based on spectrophotometry of the inhibition by free phenytoin of the precipitating reaction between anti-phenytoin antibody and a phenytoin-human serum albumin conjugate. A serum test sample is simultaneously mixed with the phenytoin-albumin c...
متن کاملPerformance evaluation of the Elecsys syphilis assay for the detection of total antibodies to Treponema pallidum.
Syphilis is a health problem of increasing incidence in recent years that may have severe complications if not diagnosed and treated at an early stage. There are many diagnostic tests available for syphilis, but there is no gold standard, and diagnosis therefore usually relies upon a combination of tests. In this multicenter study, we evaluated the treponemal Elecsys syphilis assay for use in t...
متن کاملElecsys insulin assay: free insulin determination and the absence of cross-reactivity with insulin lispro.
of 0.2 mgzkgzh are presented in Fig. 1, B and C, respectively. The concentration of SF recovered in the plasma sample was 0.80 mg/L. In conclusion, SPE before GC-MS represents a convenient method for quickly obtaining clean extracts with optimum recoveries and could be an accurate analytical tool for the monitoring of SF concentrations in plasma samples during pharmacokinetic studies. Reference...
متن کاملEvaluation of Elecsys Syphilis Assay for Routine and Blood Screening and Detection of Early Infection
Treponema pallidum infections can have severe complications if not diagnosed and treated at an early stage. Screening and diagnosis of syphilis require assays with high specificity and sensitivity. The Elecsys Syphilis assay is an automated treponemal immunoassay for the detection of antibodies against T. pallidum The performance of this assay was investigated previously in a multicenter study....
