ImmoCare-C is an immunological test and thus a considerably improved method for detecting invisible blood in the stool. The test uses specific antibodies to trace the red blood pigment. This allows bowel cancer and its precursors as well as other abnormalities to be detected.
The PSA value (prostate-specific antigen) is well established as a tumour marker. From the age of 50 it is covered by social insurance and therefore free of charge.
