Hemoglobin correction for lipemia

WebAt 1.8 g/L, a positive relationship was found between the bias and the hemoglobin supernatant level only for fibrinogen measurement, using optical detection. For icteric interference, no significant bias was observed until a bilirubin concentration of 30 mg/dL. Lipamia (>500 mg/dL) led to analytical interference when using the optical analyzer. Web11 apr. 2024 · A method of estimating an interference‐free value for FRUC,HDLc, PROT, Phos, UA,TG, and CREA, and for CHOLTin cases of cholestasis, is proposed. Iictlevels are identified based on analytical performance goals, and equations to recalculate interference‐free values are also proposed.

WebThe second mechanism by which hemolysis affects test accuracy and reliability is through interference from hemoglobin itself. Due to its red color, hemoglobin absorbs light between 340–440 nm and 540–580 nm, allowing it to interfere with assays across a broad range of wavelengths.
