Binding assay for the in vitro quantitative determination of folate in human serum. The binding assay is intended for use on Elecsys and cobas e immunoassay analyzers. Folic acid measurements are used in the diagnosis and treatment of anemias.
Device Story
Elecsys Folate III is an in vitro diagnostic immunoassay for human serum folate quantification. It uses a competitive binding principle: folate in the sample competes with biotinylated folate for binding sites on a ruthenium-labeled folate binding protein (FBP). Streptavidin-coated microparticles capture the complex. The device is used on Elecsys and cobas e immunoassay analyzers in clinical laboratory settings. Operation involves automated processing where the analyzer measures electrochemiluminescence signals. Results are calculated via a 2-point calibration and a master curve provided by reagent bar codes. Healthcare providers use these measurements to diagnose and treat anemias. The device benefits patients by providing standardized folate levels to guide clinical management.
Clinical Evidence
Bench testing only. Precision evaluated per CLSI EP5-A2 (n=84); total CVs ranged 3.7-10.8%. Linearity confirmed 2-20 ng/mL (R²=0.997). LoB 0.64 ng/mL, LoD 1.2 ng/mL, LoQ 2.0 ng/mL. Method comparison against Abbott Architect Folate (n=106) yielded y = 0.976x + 0.041 (r=0.984). Reference range established using 214 healthy adults (4.8-24.2 ng/mL). No clinical diagnostic studies performed.
Technological Characteristics
Competitive immunoassay; ruthenium-labeled folate binding protein; biotinylated folate; streptavidin-coated microparticles. Chemiluminescence detection. Analyzers: Elecsys/cobas e series. Standards: CLSI EP5-A2, EP17-A2, EP6-A, EP-09-A2-IR. Traceability: WHO International Standard NIBSC 03/178. Measuring range: 2.0-20.0 ng/mL.
Indications for Use
Indicated for the quantitative determination of folate in human serum to aid in the diagnosis and treatment of anemias in adult patients. Contraindicated for patients receiving therapy with methotrexate or leucovorin due to cross-reactivity.
Regulatory Classification
Identification
A folic acid test system is a device intended to measure the vitamin folic acid in plasma and serum. Folic acid measurements are used in the diagnosis and treatment of megaloblastic anemia, which is characterized by the presence of megaloblasts (an abnormal red blood cell series) in the bone marrow.
