Method for rapid detection of hepatocyte growth factor in biological fluids

A method for determining the presence, absence or amount of biologically active Hepatocyte Growth Factor (HGF) in a fecal sample of a subject and correlating said presence, absence or amount of HGF with an acute inflammation of the bowel in the subject, said method comprising the steps of:

• bringing the fecal sample in contact with a first and a second porous solid phase of a test strip, said first and second porous phases being fixed to a solid support, said first porous phase comprising at least one HGF binding component of the extracellular matrix or cell membrane, and an HGF indicator composition in contact with the HGF binding component, said HGF indicator composition comprising bromothymol blue and a quaternary ammonium compound, said second porous phase comprising a pH indicator composition fixed to said second porous phase, said pH indicator composition comprising bromothymol blue, a quaternary ammonium compound and methyl red;
• and
• correlating the colour of the first porous solid phase with the color of a reference solution containing a known quantity of biologically active HGF and thereby determining presence, absence or amount of biologically active HGF in the fecal sample and determining the pH of the fecal sample from said second solid phase, wherein the presence of an amount or biologically active HGF in said fecal sample is indicative of an acute inflammation of the bowel in the subject when the pH of said fecal sample is >8 and wherein said HGF binding component is heparin sulphate proteoglycan or dextran sulphate, wherein the fecal sample is a fluid.
