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.
