浆膜腔积液是一常见的体征,病因复杂。胸、腹水实验检查一般分为漏出液与渗出液两大类,如果单纯根据传统的常规标准,区分有时不够可靠,因为蛋白含量可因病因不同、利尿、输入蛋白和门脉压的进展等而有所波动,故胸、腹水除作常规检验外,尚需辅以其它的鉴别方法。Light等用胸、腹水蛋白/血清蛋白>0.5,胸、腹水LDH/血清LDH>0.6或LDH>200Iu的三条指标作为诊断渗出液的依据。文献报道结合免疫球蛋白或乳酸测定有助于渗出液的诊断。Hamm等将胸、腹水TCH含量1.43mmol/L作为区别漏出液与渗出液的分界线。上述方法能有效地区别漏出液与渗出液,但均操作
Serous effusion is a common sign, the cause is complicated. Chest, ascites and laboratory tests generally divided into two categories of leakage and exudate, if simply based on traditional conventional standards, the distinction is sometimes not reliable, because the protein content can be due to different etiologies, diuresis, input protein and portal pressure progress And some fluctuations, so chest, ascites except for routine testing, still need to be supplemented by other identification methods. Light and other three indicators of chest, ascites protein / serum protein> 0.5, chest, ascites LDH / serum LDH> 0.6 or LDH> 200Iu as the basis for the diagnosis of exudate. It has been reported in the literature that the combination of immunoglobulins or lactic acid assays contributes to the diagnosis of exudates. Hamm and other chest, ascites TCH content of 1.43mmol / L as the difference between the leakage of leakage and exudate line. The above method can effectively distinguish between leachate and exudate, but both operate
