First type hepatitis is by the first type hepatitis virus (HAV) Through the excrement - a kind of infective disease relying mainly on the fact that the liver is damaged caused that the mouth route is transmitted. Presenting global distribution, children and crowds of teenagers occur frequently. Get up disease to be worried and sudden, 1-5 days such as prodromal stage, generate heat, whole body is uncomfortable, similar cold symptom; Unless then it is weak since it appear obviously, detest by oil food, unless sick, vomit,etc., let's misdiagnose often for " Gastritis " . So someone summarizes: Cold adds gastritis, it is hepatitis to watch out for. The eyes are yellow subsequently, the urine is yellow like the strong tea. Should check the virology index at first while making a definite diagnosis of first type hepatitis: ( 1) Resist - HAVIgM: Jaundice can be measured when appears, it keeps the same with time that clinical symptom and biochemical index are unusual, the antibody is dripped degree and positive rate and dropped 1-2 months later, basically disappear in 3-4 months. It is the major indicator that hepatitis A diagnosed in early days. But specific patient negative the beginning disease have, 2-3 week the intersection of rear and detection masculine gender. Doubt, examine first type hepatitis while being clinical, resist and HAVIgM negative, should repeat for 1-2 times, so as not to leak and examine. The commonsense method has enzymes that unites the immunity to absorb and test (ELISA) With firm to radiate immunity test (SPRIA) . This experimental sensitivity is high, and simple and convenient and fast. ( 2) Resist - HAVIgG acute issue appear later stage and convalescence. )Belong to the protective antibody, can protect human body from infecting again.
