It is a personal decision. Some do and some don't. Liver biopsy is a common procedure and the risk is very low, though not zero. And it does answer your doctor's question about liver condition.
So should i go ahead with the liver biopsy ?
Thanks a lot for your useful comments.
You have HBeAg+ HBV and your high HBVDNA is expected. Whether your liver is being hurt is uncertain. Liver biopsy can answer that question. Some patients with high HBVDNA but less then 2x upper limit ALT are monitored only until they become HBeAg- when HVDNA comes down.
