Can I get checked for that at my local std clinic?
Can be called also anti-hbs, hbs antibodies.
Blood test hbsab quantitative
I'm 20 years old and so it doesn't prevent lifelong protection if all 3 doses are administered? How do I check heb b antibody?
It keeps for 10 to 20 years. You need to check if hbsab is greater than 10iu/ml you are immune, but if it gets below 100 you need a vaccina shot again.
