In addition, we present a new procedure of sequential covalent immunotudbidimetric of IgG and bovine serum albumin BSA that improves the reagent colloidal stability and could eliminate most of the drawbacks of the light-scattering immunoassays, such as nonspecific agglutination.

Development of an automated immunoturbidimetric ferritin assay.

Biochemical markers and hematologic indices in the diagnosis of functional iron deficiency. For the immunopurified anti-CRP antibodies, we used a modified procedure consisting of two sequential covalent coupling steps. Auomated ferritin assay is an automated immunoturbidimetric method. We chose this microparticle reagent, with a coverage of 0.

Diagnostic use of serum ferritin encompasses prelatent and latent iron deficiency as well as iron overloading. Lancet ; Clin Chem Lab Med ; We have developed a new procedure for turbidimetric measurement of ferritin concentration in human serum, based on latex microparticle agglutination technology. Conditions for CRP determination.

Clin Chem ; 42 Suppl 6: We suggest an alternative approach that uses a small amount of immunopurified antibody and stabilizes the reagent by saturation of free surface with BSA in a two-step sequential covalent procedure.

Samples with CRP values above the upper limit of the calibration curve can be reanalyzed after automated or manual sample dilution. It is also used to distinguish between hypoferric anemia and hypochromic anemia chronic infection and tumor anemias, sideroblastic anemia or thalassemia. We then selected 0. Skip to main content.

Development of an automated immunoturbidimetric ferritin assay.

It allows lower antibody coverage on the microparticle reagent and provides highly sensitive and robust particle-enhanced turbidimetric immunoassay for serum CRP. We describe a microparticle reagent that we use in an optimized turbidimetric procedure with immunopurified polyclonal antibodies against CRP.

The procedure has been automated using the Falcor analyzer. Research Article Technical Brief. Clinical Chemistry Nov46 11 .
