The normal value of B-type brain natriuretic peptide precursor is less than 100pg/mL.
Pro-B-type brain natriuretic peptide (pro-BNP) is a biomarker used to assess heart function and cardiovascular disease. Under normal circumstances, the normal value of B-type brain natriuretic peptide precursor should be less than 100pg/mL. As age increases, the normal value will increase. For people over 75 years old, the normal range should be controlled below 450pg/mL. This is because as we age, heart function declines, leading to increased levels of B-type natriuretic peptide precursors. The range of normal values ??will also vary for different age groups. Doctors usually interpret the B-type pro-brain natriuretic peptide test results based on the patient's age and other relevant factors, and conduct a comprehensive evaluation combined with clinical symptoms.
