NT-proBNP ELISA Kit
為什么要檢測(cè)NT-proBNP ?
NT-proBNP是 proBNP分解后的76氨基酸片段。proBNP是心臟為彌補(bǔ)收縮無力而增大時(shí),心壁被拉伸時(shí)由心臟釋放到血液中的化學(xué)物質(zhì)。一旦從心臟釋放到血液中,proBNP就會(huì)分割為NT-proBNP和BNP。由于NT-proBNP的半衰期為120min,相比之下,BNP的半衰期僅20min。所以NT-proBNP可追蹤的時(shí)間可達(dá)24h而BNPzui多可監(jiān)測(cè)的時(shí)間為1h。因此,檢測(cè)血清/血漿中的NT-proBNP穩(wěn)定性更好,檢測(cè)結(jié)果更可靠,是有效的心衰檢測(cè)工具。
