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 ...
متن کاملSerum fructosamine in diabetic pregnancy.
Serum fructosamine was measured in 275 blood donors, in 559 subjects with a normal pregnancy, in 32 gestational diabetics being treated with insulin and 69 being treated by diet only, and in 53 pregnant subjects with established diabetes. In none of the pregnant subgroups did the mean fructosamine concentration exceed that of the donor group. The concentration in normal pregnant subjects showed...
متن کاملRelative potency of commercial calibrators for fructosamine, and their effect on measurements of fructosamine in serum.
The protein-based secondary standardsfor serum fructosamine in a commercial test kit (Roche Diagnostics) have recently been modified by the manufacturer. Under certain assay conditions, the new calibrator gave significantly greater serum fructosamine values than those obtained with the originally supplied calibrator. However, for 20-4, samples and absorbance measurements at 10 and 15 mm, hereaf...
متن کاملStability of plasma enzymes during storage.
For measurement of plasma enzyme stability, 18 specimens of whole blood, plasma, and serum from normal subjects were stored at different temperatures. Eight enzymes were assayed after different times of storage: acetytcholinesterase, pseudocholinesterase, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactic dehydrogenase, acid and alkaline phosphatases, and amylase. At _200 ...
متن کاملFructosamine assay using albumin extracted from serum.
Albumin extracted from serum by a simple technique using trichloroacetic acid and ethanol has been applied to a fructosamine assay using nitroblue tetrazolium. A fructosamine assay using extracted albumin sample was carried out without interference from low molecular weight substances with reducing activities and other proteins with varying concentrations, half-lives and reducing activities. 1-...
