look over the guidelines to learn about the stage of hepatitis B you are currently in and about the progression of hepatitis b.
some experts believe in early treatment while other like the wait and see approach. What I can tell you is that you need to have a fibroscan to check your liver stiffness. This will determine if you need treatment right away or the wait and see approach. The good news is that DNA 1000 iu/ml and hbsag quant 1473 is quite good w/o treatment. I am not a doctor but to start treatment doctors usually will check , hbeag , ast , alt, fibroscan, family history, dna, and hbsag quant, ultrasound age, genotype, mutations and kidney function.
