Additional Information
Limitations
Concentrations of natriuretic peptides may be elevated in patients with acute myocardial infarction, patients that are candidates for renal dialysis, and patients that have undergone renal dialysis.
Patient samples may contain heterophilic antibodies that could react in immunoassays to give falsely elevated or depressed results,. This assay has been designed to minimize this interference.
