PROBLEM TO BE SOLVED: To obtain an inspection result that becomes useful information of the prognosis, etc., of a kidney disease by detecting fat acid bound protein derived from a kidney tissue that exists in a sample sampled from a mammal other than rodents. ;SOLUTION: A fat acid bound protein derived from a kidney tissue that exists in a sample sampled from a mammal other than rodents is detected. The mammal other than rodents includes humans, rabbits, and pigs and application thereof is preferably made to humans. In the kidney tissue at least two types of fat acid bound proteins are developed, namely a kidney type, and another one is a cardiac muscle type. The fat acid bound protein(FABP) derived from the kidney tissue includes a kidney type fat acid bound protein (L-FABP), and a cardiac muscle type fat acid bound protein (H-FAB). With the development of ABP, the larger is the amount of development, the better the prognosis of the kidney disease is. The sample to be inspected being applied includes urine, blood, an extract liquid from the kidney tissue, or the like.;COPYRIGHT: (C)1999,JPO
