Assay Procedure

This product is compatible with various types of automated analyzers. An example of the assay procedure is shown below.

Assay Procedure
  1. *1Use spot or pooled urine as the sample.
    (do not use acidic urine or pooled urine containing toluene)
  2. *2Absorbance Ⅰ and Ⅱ:Difference between absorbance at 570nm and at 800nm

Calibration material:L-FABP Calibrator (manufacture's assigned value)
Reagent blank:Saline

Assessment of Assay Results

  1. 1Correction of Assay Results

    Assay results should be corrected for urinary creatinine concentration to calculate the L-FABP level (µg/gCr) per gram of urinary creatinine.
    [Conversion formula] L-FABP(µg/gCr) = L-FABP(ng/mL) / Cr(mg/dL) × 100

  2. 2Reference Interva

    The reference Interval calculated from the urinary L-FABP level in 412 healthy humans has been reported to be not more than 8.4 µg/gCr.6)
