    • The object of the present invention is a method of diagnosis of a chronic kidney disease (CKD) or glomerulopathy in a subject, comprising the following steps: (a) determination of the level of at least five, or at least six or at least seven protein markers selected from the group consisting of Ig gamma-2 chain C region (IGHG2), serum albumin (ALB), ceruloplasmin (CP), thrombin (F2), haptoglobin beta chain (HP), alpha-1-antitrypsin (SERPINA1), Ig kappa chain V-1 region HK102 (IGKV1-5), myoglobin (MB), alpha-1-acid glycoprotein 1 (ORM1), serotransferrin(TF), alpha-1 B-glycoprotein (A1 BG), Igkappa chain V-I region Daudi (P04432), ganglioside GM2 activator (GM2A), alpha-1-acid glycoprotein 2 (ORM2), zinc-alpha-2-glycoprotein (AZGP1), afamin (AFM), NHL repeat-containing protein 3 (NHLC3), inter-alpha-trypsin inhibitor heavy chain H2 (ITIH2); wherein said markers also comprise the non-full-length fragments thereof, in a urine sample from said subject and (b) assigning a probability of the subject having or being at a risk of chronic kidney disease or glomerulopathy based on the results of the assay of step (a), wherein this involves: (i) determining the probability of the patient having a particular glomerulopathy based on the level of a first marker one of the markers determined in step (a), the probability being estimated based on the levels of said first marker determined in subjects known to have the particular glomerulopathy; (ii) determining the probability of the patient having a particular glomerulopathy based on the level of a second marker one of the markers determined in step (a), the probability being estimated based on the levels of said second marker determined in subjects known to have the particular glomerulopathy; (iii) conducting the calculations of (i) as required for further markers determined in step (a); (iv) determining the probability of the subject, providing the urine sample tested in step (a), having or being at a risk of each of the assessed glomerulopathies as a multiplication product of the corresponding probabilities obtained from each marker in (i)-(iii). A further object of the present invention is a method of monitoring a response to treatment, comprising the following steps: (a) determination of the level, at a first point in time, of at least five, or at least six or at least seven protein markers selected from the group consisting of Ig gamma-2 chain C region (IGHG2), serum albumin (ALB), ceruloplasmin (CP), thrombin (F2), haptoglobin beta chain (HP), alpha-1-antitrypsin (SERPINA1), Ig kappa chain V-1 region HK102 (IGKV1-5), myoglobin (MB), alpha-1-acid glycoprotein 1 (ORM1), serotransferrin (TF), alpha-1 B-glycoprotein (A1 BG), Ig kappa chain V-I region Daudi (P04432), ganglioside GM2 activator (GM2A), alpha-1-acid glycoprotein 2 (ORM2), zinc-alpha-2-glycoprotein (AZGP1), afamin (AFM), NHL repeat-containing protein 3 (NHLC3), inter-alpha-trypsin inhibitor heavy chain H2 (ITIH2); wherein said markers also comprise the non-full-length fragments thereof, in a urine sample from a subject; (b) repeating the assay of step (a) at a later point in time after a period wherein the subject was undergoing a treatment; (c) assessing a response to said treatment by comparing the results of the assays of steps (a) and (b), wherein lower marker levels after treatment are indicative of a positive response to treatment. A further object of the present invention is a method of treatment of a chronic kidney disease (CKD) or glomerulopathy in a subject, comprising the following steps: (a) determination of the level of at least five, or at least six or at least seven protein markers selected from the group consisting of Ig gamma-2 chain C region (IGHG2), serum albumin (ALB), ceruloplasmin (CP), thrombin (F2), haptoglobin beta chain (HP), alpha-1-antitrypsin (SERPINA1), Ig kappa chain V-1 region HK102 (IGKV1-5), myoglobin (MB), alpha-1-acid glycoprotein 1 (ORM1), serotransferrin (TF), alpha-1 B-glycoprotein (A1 BG), Ig kappa chain V-I region Daudi (P04432), ganglioside GM2 activator (GM2A), alpha-1-acid glycoprotein 2 (ORM2), zinc-alpha-2-glycoprotein (AZGP1), afamin (AFM), NHL repeat-containing protein 3 (NHLC3), inter-alpha-trypsin inhibitor heavy chain H2 (ITIH2); wherein said markers also comprise the non-full-length fragments thereof, in a urine sample from said subject and (b) assigning a probability of the subject having or being at a risk of chronic kidney disease or glomerulopathy based on the results of the assay of step (a), wherein this involves: (i) determining the probability of the patient having a particular glomerulopathy based on the level of a first marker one of the markers determined in step (a), the probability being estimated based on the levels of said first marker determined in subjects known to have the particular glomerulopathy; (ii) determining the probability of the patient having a particular glomerulopathy based on the level of a second marker one of the markers determined in step (a), the probability being estimated based on the levels of said second marker determined in subjects known to have the particular glomerulopathy; (iii) conducting the calculations of (i) as required for further markers determined in step (a); (iv) determining the probability of the subject, providing the urine sample tested in step (a), having or being at a risk of each of the assessed glomerulopathies as a multiplication product of the corresponding probabilities obtained from each marker in (i)-(iii); (c) administering treatment against a chronic kidney disease (CKD) or glomerulopathy in the subject evaluated in step (b) as having or being at a risk of chronic kidney disease or glomerulopathy, according to the particular glomerulopathy determined in step (b) (iv).
