有不少家长来信问,其本人或孩子经化验血为表面抗原阳性,不知其意义,提出了一系列问题:是否为肝炎?急性还是慢性?有无传染性?该用什么药治疗?会不会转为阴性?等等。表面抗原检测是判定是否有传染性肝炎的参考,传染性肝炎是由病毒引起,有多种病毒可引起肝炎,到目前为止比较肯定的甲型肝炎病毒、乙型肝炎病毒、非甲非乙型肝炎病毒,由此而引起甲型肝炎、乙型肝炎和非甲非乙型肝炎。这三型肝炎均有传染性,统称为传染性肝炎。这三种肝炎虽然各有其特征性表现,但单凭其发病经过、临床表现、病情轻重、发展情况等,难以作出肯定性结论,到底属于那一型肝炎,还必须测定有关的化验检查结果。表面抗原测定主要用于判定是否为乙型肝炎。
There are many parents letter to ask, the person or child by blood test for the positive surface antigen, I do not know its significance, put forward a series of questions: whether it is hepatitis? Acute or chronic? Is there any infectious? What medicine should be treated? Will not Will become negative? And so on. Surface antigen testing is to determine whether there is a reference for infectious hepatitis, infectious hepatitis is caused by a virus, a variety of viruses can cause hepatitis, so far relatively positive Hepatitis A virus, hepatitis B virus, non-A non-B Hepatitis virus, which causes hepatitis A, hepatitis B and non-A, non-B hepatitis. These three types of hepatitis are contagious, collectively referred to as infectious hepatitis. Although each of these three hepatitis have their own characteristic manifestations, it is difficult to make affirmative conclusions based solely on their pathogenesis, clinical manifestations, severity of illness, and development status. In the end, those hepatitis types must also test the results of laboratory tests . Surface antigen assay is mainly used to determine whether the hepatitis B.
