Patient's question:
Hello! The test results showed IgM positive, but there were no blisters or erosion when examined in the vagina. What could be the situation? I have been on intravenous drip for 14 days and have taken valacyclovir tablets for six months, yet it is still positive. How is this possible?First follow-up question: What kind of test can determine if there is a recurrence? How long has it been since the last recurrence? After more than half a year of treatment, it hasn’t been cured, and I’m almost losing hope in treatment. If I stop, what serious consequences might occur?
Doctor's answer:
Hello, IgM antibody for hepatitis A is the earliest antibody to appear after infection with the hepatitis A virus, typically emerging within one week of onset. A positive detection indicates early acute infection with the hepatitis A virus, serving as a marker for acute infection. It can persist in the blood for 3 to 6 months. Therefore, a positive IgM antibody for hepatitis A suggests either acute infection or recurrence, and only a single acute-phase serum test is required for diagnosis.
