The technical grade porcine thrombin (90 - 350 U/mg protein) is used by diagnostic companies worldwide to defibrinate plasma, producing serum matrixes to be used as controls and standards or in polyclonal antibody production. Using porcine thrombin in polyclonal antibody production to defibrinate plasma may increase antibody yields by 15-20% over off-the-clot methods of defibrination. (BioPharm Defibrination Protocol)

IgM是免疫球蛋白M(Immunoglobulin M,IgM)的缩写。根据结构的不同将免疫球蛋白分为五种,IgM是人的免疫球蛋白之一,其他还有lgA、lgG、IgD和lgE。
HSV1型导致的一般都是腰部以上的感染,典型症状是水泡有可能引起脑炎,而且有非活化状态的潜伏。所以我觉得你根本就不用担心这个抗体IgG阳性的化验单。
2-IgM也是一种特异性感染指标,但在人体内持续时间不长(有时是30天更短),往往是传染病的近期感染指标。呈阴性是指:你近期没有感染过结核杆菌。
