Abstract: A method for the diagnosis of bladder cancer (BC) and/or for determining a tumor stage of bladder cancer, comprising the step of determining the presence or absence or amplitude of at least six polypeptide markers in a sample, wherein said polypeptide markers are selected from markers 1 to 836, which are characterized by the values for the molecular masses and migration times (CE time).

Abstract: A method for recognizing rejection after a kidney transplantation (NTx), comprising the step of determining the presence or absence of at least one polypeptide marker in a sample, wherein said polypeptide marker is selected from markers 1 to 242 (frequency markers), or determining the amplitude of at least one polypeptide marker selected from markers 243 to 767 (amplitude markers), which are characterized by the values for the molecular masses and migration times (CE time).

Abstract: Devices and processes for the quantitative evaluation of the polypeptides contained in a sample of body fluid and markers for recognizing pathological conditions are described. The polypeptides are compared with reference values stored in a data base. These reference values are stored as data records of polypeptides relevant to the condition, which respectively comprise at least some information about the probability of the occurrence and/or the concentration of the polypeptides for a pathological condition in samples of healthy and diseased subjects.

Abstract: Certain embodiments of the invention relate to means and methods for the diagnosis of a renal disease, particularly to differential diagnosis. Renal diseases of particular interest in the context of the invention are IgA-nephropathy, membranous glomerulonephritis (MGN), minimal-change-disease (MCD), focal segemental glomerulosclerosis (FSGS), and diabetic nephropathy.
