Standardization of serum fructosamine assays.
We have calibrated a secondary serum protein standard by use (as primary standards) of samples of albumin and polylysine glycated with [14C]glucose in vitro, the glycation of which was assessed by radioactivity measurements and by elementary analysis for C and N. Using this standard for calibration in our improved fructosamine assay, one obtains an average fructosamine value of 247 mumol/L for ...

During 1969, discussions between the Standards Subcommittee of the Laboratory Equipment and Methods Advisory Group of the Department of Health and Social Security and representatives of professional societies concerned with the assay of enzymes for diagnostic purposes led to the establishment of a working party to consider the current state of accuracy and reliability of diagnostic enzymology a...
متن کاملThe need for standardization of tacrolimus assays.
BACKGROUND Owing to the lack of an internationally recognized tacrolimus reference material and reference method, current LC-MS and immunoassay test methods used to monitor tacrolimus concentrations in whole blood are not standardized. The aim of this study was to assess the need for tacrolimus assay standardization. METHODS We sent a blinded 40-member whole-blood tacrolimus proficiency panel...
متن کاملStandardization of assays for human chorionic gonadotropin.
The unsatisfactory standardization of many immunoassays is fairly well recognized, but the problem is hard to tackle (1 ). Recently, studies on the performance of immunoassays for testosterone in female serum (2 ) and for urinary cortisol (1 ) have revealed that the quality of some widely used assays is totally unsatisfactory. The quality of assays for human chorionic gonadotropin (hCG) has als...
متن کاملProposals for standardization of total protein assays.
The Standards Committee of the AACC presents a discussion of the nature of total serum protein and the problems associated with its determination. Proposals are made that protein be defined as polypeptide material, and that a reference preparation be promuJgted for interlaboratory use. The reference material suggested is bovine serum albumin, produced to rigid specifications and distributed as ...
