WebSep 4, 2024 · Background: The use of RBC lysate (RBC-Lys) eliminates the need for serum folate and hematocrit (Hct) measurement to calculate RBC folate. Information on the long-term frozen storage stability of RBC-Lys is missing. Objectives: We aimed to assess the comparability of RBC folate forms in whole-blood lysate (WB-Lys) and RBC-Lys and the … WebThe commonly accepted technique for RBC folate analysis involves preparation of a hemolysate using a fresh whole blood sample. Hematocrit and plasma folate concentrations are needed to calculate RBC folate values. Folate is essential for normal …

WebRBC − folate = [(Whole blood hemolysate folate × 10) − total plasma folate (1 − Hct)] / Hct The individual total plasma folate levels were approximated as the sum of plasma 5-MTHF and hmTHF levels, and hematocrit (Hct) results were used as decimal values (i.e., 0.40). WebSerum folate is measured by using the Bio-Rad Laboratories "Quantaphase II Folate" radioassay kit. The assay is performed by combining serum or a whole blood hemolysate sample with 125I-folate and cyanide. The mixture is boiled to inactivate endogenous folate-binding proteins.
