HBV DNA Testing

I had an Hepatologist clear me for Hep B by validating my immunity from Hep B Panel testing conducted over the course of 2 years (4) different test where each time my HBsAG remain negative & HBsAb antibodies are positive thankfully & Total Core Igm/IGg now reflects previous exposure positive which was unclear before however my antibody HBeAb was positive as well on 1 test result. After all this the Hepatologist still doesn't see a need to test HBV DNA due to normal LFT(liver test) Levels. Would anyone here disagree here? and feel it is still necessary to do the HBV DNA to guarantee my ability not to be infectious?

dna is absolutely useless you just have to check hbsab quantity and if >10miu/ml it protects and if higher than 250miu/ml even better

My HBsAB is 6.78 this result is also 17 years after exposure CDC, HEP Org & now a Hepatologist says I'm IMMUNE still I want to be absolutely sure I AM so will the HBV DNA do me any good to consult immunity?  If so why? If Not then why Not? Please explain...
