The former preponderates on the initial stage of infecting, drip degree and drop 3 months later, the difficult detection after 6- 8 months; The latter drips degree relatively low in initial stage, and then raise gradually, this antibody can still keep quite dripping degree after the recovery, it can last several years or a longer time. Only infecting in early days because of resisting HAVIgM, does not appear again at the time of the second infection, it is to infecting the sensitive index diagnosed in early days recently, diagnose the most simple and most convenient method of first type hepatitis at present too. So resist HAV is 1gM positive to brief on for being acute to infect or recur, need, measure acute issues of the intersection of form and copies of serum, can make diagnosis immediately only. And then combine epidemiology to investigate, like there is hepatitis A that contacts the history, eat not clean diet history such as the hair cricket; Have typical clinical manifestation such as the intersection of whole body and weak, the intersection of appetite and drop, sick, vomit, yellow to detest the greasy food urine, check GPT and obviously rise in liver function, the diagnosis of the first type hepatitis can basically be fixed. The ones that diagnosed the auxiliary project of hepatitis A has in various secretion resisted HAV-1gA, HAV virus particle in the excrement and urine,etc..
