PROBLEM TO BE SOLVED: To provide a measurement method of total PSA which has a high sensitivity and a wide measurement range and is capable of commonly measuring the reactivity of a free prostate specific antigen (fPSA) and a prostate specific antigen/α1-antichymotrypsin complex (PSA-ACT), and to provide a measuring kit.SOLUTION: The measurement method includes the steps of: adding, to a sample, Fab or Fab' fragment of an antibody which reacts to an fPSA but does not react to a PSA-ACT; and adding an antibody which reacts to both of the fPSA and the PSA-ACT. The measuring kit contains an antibody which reacts to both of the fPSA and the PSA-ACT; and Fab or Fab' fragment of an antibody which reacts to the fPSA but does not react to the PSA-ACT.SELECTED DRAWING: None |
