Abstract: The invention provides a method of defining the likelihood of a subject having bladder cancer, comprising the steps of: (A) assessing the subject's likelihood of having bladder cancer by: i. identifying at least one sub-population group appropriate to the subject; ii. determining the level of one or more biomarkers selected according to the sub-population group in a sample obtained from the subject; iii. inputting each of the biomarker values into an algorithm to produce an output value; and iv. correlating the output value with the likelihood of the subject having bladder cancer, wherein the sub-population group is selected according to smoking habits, gender, presence/absence of stone disease, history of benign prostate enlargement (BPE) or prescription of anti-hypertensive, anti-platelet and/or anti-ulcer medication, and (B) determining the subject's stratified risk level of serious disease by: v.
