Comparison of the radioisotope dilution-coated charcoal method and a microbiological method (L. leichmannii) for measuring vitamin B12 in serum.
A comparison has been made of the radioisotope dilution-coated charcoal method and a microbiological assay (with L. leichmannii as test organism) for determining the concentration of vitamin B(12) in serum. A satisfactory correlation was found between the results of the two methods. Under appropriate conditions the reproducibility of the radioisotope method compared favourably with that of the ...
متن کاملAn Improved Radioisotope Dilution Assay for Serum Vitamin B 2 Using Hemoglobin - coated Charcoal
A radioisotope dilution assay for vitamin B12, using hemoglobin-coated charcoal, was modified in several respects, the most prominent of which was the use of cyanide extraction of sera. With these modifications, the B12 levels were significantly higher in sera from normal subjects and patients with folate deficiency, whereas sera from patients with pernicious anemia and other B12-deficient stat...

متن کاملThe Value of the Serum Vitamin B12 Level in Diagnosing B12 Deficiency
Serum vitamin B,2 levels of 2523 individuals were measured using the hemoglobin-coated charcoal assay. In one hespital, the test was performed on 1698 patients under hematologic evaluation for erythrocytic abnormalities of all types, while 825 patients from five other hospitals were studied because of suspected B,2 deficiency. The incidence of low serum vitamin B,2 was surprisingly low for both...
