An in vitro method for diagnosing a brain tumour in a human test subject comprising: determining the concentration of at least two metabolites comprised in a biofluid sample obtained from the human test subject; comparing the concentration of the at least two metabolites in the biofluid sample with the concentration of the same at least two metabolites in at least one reference standard obtained from a non-tumour bearing subject and/or a tumour bearing subject; and identifying a concentration difference for each of the at least two metabolites in the biofluid sample relative to the reference standard; wherein the concentration difference for each of the at least two metabolites in the biofluid sample correlates with the presence of a brain tumour. The invention also relates to a data-storage medium comprising data obtained by a method of the invention.
