Nine rheumatoid factor assays compared.
In this study we have investigated five quantitative and three semi-quantitative rheumatoid factor assays and the Rose-Waaler assay in 120 patients suffering from rheumatoid arthritis and in 76 with other systemic diseases. All tests measure the IgM anti-IgG antibodies. The correlations between the quantitative tests were all higher than 0.86 and much better than between the quantitative and se...
متن کاملSix osteocalcin assays compared.
We evaluated comparatively six commercially available osteocalcin kits: ELSA-OST-NAT IRMA (CIS), ELSA-Osteo IRMA (CIS), Osteocalcin IRMA (Nichols), OSTK-PR RIA (CIS), OSCA Test Osteocalcin RIA (Henning), and Osteocalcin RIA (Nichols). All of them presented acceptable values of variance, sensitivity, and serial dilutions. However, only the ELSA-OST-NAT, ELSA-Osteo, and OSCA Test kits had analyti...
