The stabilizing agent is able to stabilize proteases in the biological sample, particularly at the point of collection, by inhibiting protein degradation and/or fragmentation in the sample when the sample is stored. The stabilizing agent comprises or consists of one or more protease inhibitors.10 20 22 24 -14 12 18 FIG.1 1/8
