    摘要: The invention provides a method for determining concentration of myeloperoxidase (MPO) in a human blood sample comprising: (a) providing a human peripheral blood sample stored under MPO preservation conditions; and (b) determining concentration of MPO in a plasma sample derived from the human peripheral blood sample. In a preferred embodiment, the MPO preservation conditions used in the invention comprise storage of the human peripheral blood sample in a plasma collection tube containing a leukocyte MPO secretion inhibitor. In this embodiment, the leukocyte MPO secretion inhibitor is preferably ethylene diamine tetraacetic acid (EDTA). The assays used in the inventive methods can comprise any clinically useful assay for determining MPO plasma concentration, including sandwich and competitive immunoassays, clinical chemistry assays and enzymatic assays.
