[Evaluation of ARCHITECT HCV core antigen assay].
BACKGROUND Hepatitis C virus (HCV) core antigen (Ag) levels are known to be well correlating with HCV RNA levels, and may be used as an alternative marker of HCV replication for monitoring the response to HCV treatment. However, the low sensitivity of HCV core Ag assay has been an obstacle for clinical use. In this study, recently developed ARCHITECT HCV Ag assay (Abbott Laboratories, USA) was ...
متن کاملPerformance characteristics of the ARCHITECT anti-HCV assay.
INTRODUCTION The ARCHITECT Anti-HCV assay is a fully automated high throughput chemiluminescent microparticle immunoassay (CMIA) for the detection of antibodies to structural and nonstructural proteins of the hepatitis C virus (HCV). To further enhance the performance of this test, the assay was modified to improve the specificity for blood donor specimens. METHODS The specificity of the enha...
متن کاملPerformance characteristics of the ARCHITECT Active-B12 (Holotranscobalamin) assay.
BACKGROUND Vitamin B12 (cobalamin) is a necessary cofactor in methionine and succinyl-CoA metabolism. Studies estimate the deficiency prevalence as high as 30% in the elderly population. Ten to thirty percent of circulating cobalamin is bound to transcobalamin (holotranscobalamin, holoTC) which can readily enter cells and is therefore considered the bioactive form. The objective of our study wa...
متن کاملEvaluation of the Abbott ARCHITECT HCV Ag Assay
Eight hundred and three samples from a single HCV antibody negative diagnostic population were tested on the Abbott ARCHITECT HCV Ag assay. All samples initially reactive were retested in duplicate. Samples repeatedly reactive were tested for HCV RNA to determine the true status. Samples that were confirmed as positive were excluded from the specificity and negative delta calculations. A total ...
متن کاملMulti-site analytical evaluation of the Abbott ARCHITECT tacrolimus assay.
The objective of this study was to evaluate the analytical performance of the Abbott ARCHITECT Tacrolimus immunoassay. Proficiency panels and specimens from a population of organ transplant recipients were analyzed in 6 clinical laboratories in Europe and the United States, and the results were compared with other methods. The ARCHITECT assay requires a whole blood specimen pretreatment step wi...
