NT-proBNP ELISA Kit

為什么要檢測(cè)NT-proBNP ?

NT-proBNP 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-proBNPBNP。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)24hBNPzui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。

應(yīng)用領(lǐng)域:

  1. 心臟衰竭、急性心肌梗死(左心室功能不全)
  2. shen衰竭
  3. 肥胖癥和糖尿病

  3. CE 標(biāo)志-可用于臨床診斷
  4. 簡(jiǎn)單-傳統(tǒng)96孔板
  5. 動(dòng)態(tài)檢測(cè)范圍廣-可用于早期心衰檢測(cè)
