hi congrats if your PCR is negative. This primarily depicts that currently there is no HCV in your body but may be at some time it WAS in your body which was cleared by your own immune system.
These antibodies most probably will remain positive throughout your life.
There should be no further action require on your part. Antibodies are not harmful, nor can you ‘control’ them; they are a product of your own immune system.
Congratulations on clearing the virus—
