Claim:
1. A method of measuring lipoprotein particle number in a sample, the method comprising: a. separating a LDL fraction, an IDL fraction and a VLDL fraction in the sample by centrifugation; obtaining a photometric measurement in the LDL fraction; c. calculating a LDL particle count for the LDL fraction that is a function of the photometric measurement; d. obtaining a photometric measurement in the IDL fraction; e. calculating an IDL particle count for the IDL fraction that is a function of the photometric measurement in the IDL fraction; f. obtaining a photometric measurement in the VLDL fraction; g. calculating an VLDL particle count for the VLDL fraction that is a function of the photometric measurement in the VLDL fraction; h. separating at least one additional lipid fraction in the sample by centrifugation, the at least one additional lipid fraction selected from the group consisting of: a Lp(a) fraction and an HDL fraction; i. obtaining a photometric measurement in the at least one additional lipid fraction; and j. calculating a particle count for the at least one additional lipid fraction, wherein the particle count is a function of the photometric measurement in the at least one additional lipid fraction.
