| description | Brain natriuretic peptide (BNP) and amino-terminal proBNP (NT-proBNP) are significantly elevated in patients with heart failure because tension or stretching of the cardiac wall, such as occurs with heart failure, stimulates the synthesis of natriuretic peptides. Elevated levels are associated with adverse outcomes in both hemodialysis (HD) and peritoneal dialysis (PD) patients and are attributable to both ventricular dysfunction and decreased renal clearance. Peritoneal dialysate and plasma NT-proBNP levels are linearly related. [PMID: 21427249] This term was created for, but is not restricted in use to, the Elecsys proBNP II assay, which contains two monoclonal antibodies that recognize epitopes located in the N-terminal part (1-76) of proBNP (1-108). | |

| component | Natriuretic peptide.B prohormone N-Terminal | |
| property | MCnc = Mass Concentration | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
| system | Dial fld prt = Peritoneal dialysis fluid | |
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
| method | IA = Immunoassay: Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage. | |
