Elecsys Folate III is a binding assay that makes use of a competitive test principle using a ruthenium labeled folate-binding assay. Elecsys Folate III is a binding assay for the in vitro quantitative determination of folate in erythrocytes (red blood cells, RBC). Folate measurements are used in the diagnosis and treatment of anemia. The electrochemiluminescence immunoassay "ECLIA" is intended for use on cobas e immunoassay analyzers. Whole blood treated with anticoagulants (heparin or EDTA) is mixed with ascorbic acid solution and incubated for approximately 90 minutes at 20-25 °C. Lysis of the erythrocytes takes place, with liberation and stabilization of the intracellular folate. The resulting hemolysate sample is then used for subsequent measurement. Results are determined via a calibration curve, which is instrument-specifically generated by 2point calibration, and a master curve provided via the cobas link.

The LIAISON® Folate assay is a competitive chemiluminescence immunoassay (CLIA) for quantitative determination of Folic acid in serum. During the first incubation, Folic acid is dissociated from its binding protein. After five (5) minutes, a high pH buffer is added to prevent re-association to the binding protein. After five (5) minutes, Folic acid binds to a Folate Binding Protein on the solid phase, which competes with a Folic acid linked to an isoluminol derivative. After a third incubation, the unbound material is removed with a wash cycle. Subsequently, the starter reagents are added to initiate a flash chemiluminescent reaction. The light signal is measured by a photomultiplier as relative light units (RLU) and is inversely proportional to the concentration of Folic acid present in calibrators, controls, or samples.

The ARCHITECT Folate assay is a two-step assay for the quantitative determination of folate in human serum and plasma using chemiluminescent microparticle immunoassay (CMIA) technology. Two pre-treatment steps mediate the release of folate from endogenous folate binding protein. In Pre-Treatment Step 1, the sample and Pre-treatment Reagent 2 (Dithiothreitol or DTT) are aspirated and dispensed into a reaction vessel (RV). In Pre-Treatment Step 2, an aliquot of sample/Pre-Treatment Reagent 2 mixture is aspirated and dispensed into a second RV. Pre-Treatment Reagent 1 (potassium hydroxide or KOH) is then added. An aliquot of the pre-treated sample is transferred into a third RV, followed by the addition of Folate Binding Protein (FBP) coated paramagnetic microparticles and assay specific diluent. Folate present in the sample binds to the FBP coated microparticles. After washing, pteroic acid-acridinium labeled conjugate is added and binds to unoccupied sites on the FBP coated microparticles. Pre-Trigger and Trigger Solutions are then added to the reaction mixture; the resulting chemiluminescent reaction is measured as relative light units (RLUs). An inverse relationship exists between the amount of folate in the sample and the RLUs detected by the ARCHITECT i optical system.
