A method for testing for multiple organ failure in SIRS, which comprises determining cytochrome C in body fluid and using the determined result as an index of the multiple organ failure, and a reagent for testing for multiple organ failure in SIRS, which comprises a reagent for determination of cytochrome C in body fluid. The scaling on the longitudinal bore makes it possible to verify the position of the cutter knife in relation to the cutter head disk. The first switching unit and the second switching unit are controlled to be conductive such that the conductance of the switches be larger for the writing operation than for the reading operation.
