Present proficiency test services that use the peer group mean and statistically derived ranges of acceptability are not serving us optimally and are even counterproductive in some respects. We recommend that the target value be determined by a widel

Cyclosporin G (CsG) is less nephrotoxic than cyclosporin A (CsA) and is undergoing clinical trials for use as an immunosuppressive agent after renal transplantation. Three assays for whole-blood CsA-HPLC, RIA (INCSTAR, Cyclo-Trac SP), and FPIA (Abbot

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-multi

Creatine kinase MB (CK-MB) was measured in serum by a fluorometric enzyme immunoassay on the Stratus analyzer and by an immunochemiluminometric assay using the Ciba Corning Magic Lite System. Both methods were standardized against purified CK-MB, wit

Quality-assurance sera (QAS) are prepared from pooled sera composed of thousands of individual donations. Previous studies documented that a substantial percentage of individual QAS test positive for viral disease markers, including antibodies to hum

A rapid liquid-chromatographic method is described for simultaneously determining prednisone, prednisolone, and cortisol in plasma. Before chromatography, samples containing an internal standard (methylprednisolone) were extracted with use of Chem El

This work describes the action of the lysosomal enzymes arylsulfatase A (EC 3.1.6.1) and sialidase (EC 3.2.1.18) on human creatine kinase (CK, EC 2.7.3.2) isoenzyme BB. The isoenzyme, which gives a positive reaction with the periodic acid-Schiff reag
