Is It Okay To Take Enbrel While Having Hepatitis B?

I has had psoriatic arthritis for many years and have just been prscribed enbrel, which I have not started yet, the question I want to ask is I have worked in many jails and prisons. I had one instance about five years ago where I was involved in a physical altercation with a inmate and I got blood on my hands and I had a open cut. I know that enbrel affects people with hep b . should I get screened and if found ot to have it can I still take enbrel
