41 . A method of determining the level of two or more metabolites in a sample from a subject, the method comprising:
extracting small molecules from a biological sample obtained from the subject to produce an analytical sample; and
performing mass spectrometry on the analytical sample to determine a level of 3-hydroxypropanoate and one or more additional metabolites in the sample, wherein the one or more additional metabolites are selected from the group consisting of cinnamoylglycine, 5alpha-androstan-3beta, 17alpha-diol disulfate, adrenate, and 7-alpha-hydroxy-3-oxo-4-cholestenoate (7-Hoca).
42 . A method of determining the level of four or more metabolites in a sample from a subject, the method comprising:
extracting small molecules from a biological sample obtained from the subject to produce an analytical sample; and
performing mass spectrometry on the analytical sample to determine a level of four or more metabolites, wherein the four or more metabolites are selected from the group consisting of 3-hydroxypropanoate, cinnamoylglycine, 5alpha-androstan-3beta, 17alpha-diol disulfate, adrenate, and 7-alpha-hydroxy-3-oxo-4-cholestenoate (7-Hoca).
