Fig. 1A. The Bland-Altman plot (Fig. 1B) confirmed this random tendency, which was independent of concentration and of sex, and also demonstrated an amplified dispersion at 25-OHD concentrations Ͼ50 nmol/L. Our data (Fig. 1B) suggested that CLIA results tended to be higher than RIA at low and high concentrations , conversely to data previously published (4). With a threshold of 25-OHD Ն30 nmol/...

We compare four methods for measuring cyclosporine (CyA) in plasma and whole blood of transplant patients: HPLC, RIA with a polyclonal antibody, RIA with a monoclonal antibody, and fluorescence polarization immunoassay (FPIA). The monoclonal RIA procedure correlated acceptably with HPLC, with slope = 1.21, r = 0.97, and Sy,x = +/- 40.1. However, the FPIA, done in three separate instruments, cor...

2154 CLINICAL CHEMISTRY, Vol. 34, No. 10, 1988 Curves for successive dilutions of a purified serum extract paralleled standard curves (data not shown). No 1,25(OH)2D was detected in a charcoal-stripped serum sample. Mean concentrations in serum from 21 healthy men and premenopausal women were 54 (SD 19) ng/L (RIA 1) and 53 (SD 18) ng/L (RIA 2), respectively. Decreased 1,25(OH)2D was observed in...

OBJECTIVES Research on neurocognition in schizophrenia, using modest samples and self-rated assessments, reports drug use contributes to improved rather than impaired cognitive function. We have sought to replicate these findings in a large sample of patients that had their drug-use status confirmed by laboratory assays and evaluated the potential differences in cognitive function between patie...

In an effort to replace HPLC for whole-blood determination of cyclosporine (CsA), we compared HPLC with radioimmunoassay (RIA; INCSTAR, Cyclo-Trac SP assay), fluorescence polarization immunoassay (FPIA; Abbott TDx), and in-house modified enzyme-multiplied immunoassay technique (EMIT; Syva Co.). For blood samples from 200 various transplant recipients, RIA = 1.262 (HPLC) - 8.16, r = 0.983; FPIA ...

A description and illustrations of Monohelea maya, new species, based on male and female characteristics are provided. The specimens were collected in the special biosphere Reserves of Ria Lagartos and Ria Celestun, Yucatan State, Mexico.

These studies have evaluated a newly developed radioimmunoassay (RIA) for the measurement of colony-stimulating factor (CSF) in murine serum and other biologic fluids. The routine in vitro agar gel bioassay for CSF is influenced by high molecular weight serum lipoproteins and low molecular weight tissue-derived materials that are inhibitory to colony formation. Studies with normal serum reveale...

Radioimmunoassay (RIA) is the "gold standard" method for evaluation of serum cortisol concentration. The VIDAS cortisol test is an enzyme-linked fluorescent assay designed for the MiniVidas system. The aim of this study was to compare the VIDAS method with RIA for measurement of bovine serum cortisol concentration. Cortisol concentrations were evaluated in 40 cows using both VIDAS and RIA metho...
