Overview
BNP levels may be useful in the initial establishment of the diagnosis of heart failure in the patient with dyspnea of unclear etiology. In a meta-analysis, BNP was superior N-terminal pro-BNP (NTproBNP) and was associated with a sensitivity of 85% and specificity of 84% in the diagnosis of heart failure in the primary care setting.[1]
Once the diagnosis of heart failure is made, subsequent laboratory studies should be directed toward the identification of an underlying cause. Renal function should be assessed as a rough guide to the patient's intravascular volume status and renal perfusion. Electrolyte assessment and the correction of electrolyte disturbances such as hypokalemia, hyperkalemia and hypomagnesemia is critical in those patients treated with diuretics. The assessment of thyroid function tests is particularly important in the patient who is being treated with concomitant therapy with an agent such as amiodarone.
ACC/AHA Guidelines- Initial Clinical Assessment of Patients Presenting With Heart Failure (DO NOT EDIT) [2][3]

Class I1. Initial laboratory evaluation of patients presenting with HF should include complete blood count, urinalysis, serum electrolytes (including calcium and magnesium), blood urea nitrogen, serum creatinine, fasting blood glucose (glycohemoglobin), lipid profile, liver function tests, and thyroid-stimulating hormone. (Level of Evidence: C) Class IIa1. Measurement of B-type natriuretic peptide (BNP) can be useful in the evaluation of patients presenting in the urgent care setting in whom the clinical diagnosis of HF is uncertain. Measurement of natriuretic peptides (BNP and NT-proBNP) can be useful in risk stratification(Level of Evidence: A) |

Class IIb1. The value of serial measurements of BNP to guide therapy for patients with HF is not well established. (Level of Evidence: C) |
