Analytical correlation between plasma N-terminal pro-brain natriuretic peptide and brain natriuretic peptide in patients presenting with dyspnea.

摘要

OBJECTIVES:: We examined the analytical correlation N-terminal pro-brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP). DESIGN AND METHODS:: Electrochemiluminescence and fluorescence immunoassays were used to measure NT-proBNP and BNP levels, respectively. RESULTS:: The analytical correlation was satisfactory using the equation: NT-proBNP = 8.56 x BNP + 91.7 and a correlation r = 0.85. The correlation was not influenced by age, gender and BMI of patients. CONCLUSIONS:: We conclude that NT-proBNP correlates with BNP.
