Test cassette should be used within 1 hour after opening the pack. The N-terminal prohormone of brain natriuretic peptide (NT-proBNP) which consists of 76 amino acids, is the N-terminal fragment of the prohormone of brain natriuretic peptide. NT-proBNP level in the blood is used for screening, diagnosis of acute congestive heart failure (CHF) and may be useful to establish prognosis in heart failure, as it is typically higher in patients with worse outcome. NT-proBNP may be a useful screening tool for left ventricular dysfunction in patients with history suggestive of heart disease and be used to assist in forming a pretest probability, which in turn could greatly assist in appropriateness of patient referral and in optimization of drug therapy.Quality comes first; service is foremost; business is cooperation" is our business philosophy which is constantly observed and pursued by our company for High definition Quantitative Immunoassay Analyzer, You should really don't hesitate to call us for anyone who is fascinated within our items.
