what is your ALT at the moment?
do you have any previous ALT and DNA values?
did you do fibroscan? if you didn't you should.
test also for hbeag if you didn't in order to confirm that you are hbeag positive.
Your value is higher than 20,000 IU/ml so you have to consult with your doctor & start med. e.g Tenofo B. You should take that medicine for 2 years after your HBV DNA Quantitative is at not detectable stage.
A hbvdna of 28680 iu/ml is considered high and requires attention. It is unlikely that you are HBeAg positive and in the Immune Tolerant phase because your hbvdna would be much higher. You must check your ALT and liver function, if necessary, also a do a Fibroscan.
HBV is a chronic disease, oral antivirals must be taken to control the disease to prevent it from progressing to end-stage liver disease. It should generally be taken for a long time until HBsAg is cleared or a cure comes along.
