Evaluation of a commercial radioisotopic kit for folate assays.
نویسندگان
چکیده
A commercial kit for the radioisotopic assay of folate in serum, the Bio-Rad 'Quanta Count' folate kit, produced lower results than the Lactobacillus casei microbiological assay method. Its normal range was 2-0-13-0 microng/l and the reproducibility was similar to that of the microbiological assay method. The kit was also satisfactory for whole bood folate assays. The cost requires careful consideration before the kit is used for routine purposes.

An evaluation of commercial radioisotope methods for the determination of folate and vitamin B12.
Five commercial kits for the determination of folate and six kits for the determination of vitamin B12 were investigated. Their performance has been compared with microbiological methods for the two vitamins and with a non-commercial radioisotopic method for B12. The results show the importance of the determination of the reference range for an individual laboratory for each method. The precisi...
متن کاملEvaluation of a commercial radioassay for the simultaneous estimation of vitamin B12 and folate, with subsequent derivation of the normal reference range.
A commercial assay kit method for the simultaneous estimation of vitamin B12 and folate concentrations has been evaluated. Values derived for folate by a microbiological assay and vitamin B12 by a verified radioassay showed good correlation with the investigated method. The clinical sensitivity of the assay for detecting deficient concentrations of vitamin B12 and folate was comparable to that ...

The effects of varying the method of preparation of haemolysates on the measurement of red cell folate concentration were investigated using the Simultrac kit. The concentration of ascorbic acid did not have any significant effect on the assayed concentrations of folate, but lower concentrations were obtained when the incubation time was increased. Folate was stable for 14 days in cells when th...

متن کاملAnalytical evaluation of a folate radioassay: application to serum and erythrocyte measurements.
Many commercial folate radioassay kits have proven to be unsatisfactory in the past. It has been found that the Schwarz/Mann Iodine-125 folate radioassay kit permits a rapid measurement of folic acid requiring only a single incubation at pH 9.3. At this pH, the relative affinity of pteroylglutamic acid (FA) and N-5-methyltetrahydrofolic acid (MTFA) for the milk binder is the same. Additionally,...
