The present invention describes a method for predicting a health-state indicative of the presence of prostate cancer. The method measures the intensities of specific small biochemicals, called metabolites, in a blood sample from a patient with an undetermined health-state, and compares these intensities to the intensities observed in a population of healthy individuals and/or to the intensities previously observed in a population of confirmed prostate cancer-positive individuals. The method enables a practitioner to determine the probability that a screened patient is positive for prostate cancer. 1. A method for determining a change in prostate cancer in a patient , the method comprising the steps of:a) analyzing at least one blood sample from said patient by high resolution mass spectrometry to obtain accurate mass intensity data;b) comparing the accurate mass intensity data to corresponding data obtained from one or more than one reference blood sample to identify an increase or decrease in accurate mass intensity; andc) using said increase or decrease in accurate mass intensity to determine change in prostate cancer in said patient,wherein the accurate mass intensity is measured at one or more of the following hydrogen and electron adjusted accurate masses or neutral accurate masses, in Daltons, ±5 ppm,wherein the hydrogen and electron adjusted accurate masses or neutral accurate masses at which intensity decreases are: 174.1408, 188.1566, 194.0804, 232.9133, 242.2251, 252.2096, 258.2482, 268.2412, 272.2357, 276.2096, 278.2256, 279.2287, 280.2414, 281.2448, 283.2602, 292.204, 296.2358, 298.2519, 299.2558, 300.2098, 300.2676, 302.2256, 304.2394, 304.241, 305.243, 305.2439, 306.257, 308.2715, 310.2154, 310.2884, 312.2313, 312.304, 314.2464, 320.2358, 326.2262, 327.0326, 329.2426, 329.2445, 330.2568, 340.2977, 342.2198, 368.3437, 369.3474, 371.3538, 392.294, 411.3186, 430.3083, 430.3818, 431.3861, 432.3686, 452.2536, 481.3171, 481.3172, 482.3216, 484.3792, 492.4184 ...
