Brief Answer:
The positive refers to the RH Factor!

Detailed Answer:
Hi and thank you so much for this query.

A+ means you are blood group A Rhesus factor positive. It is no longer possible to think RH- is a possibility when written in this form.

I hope this addresses your query fully. I wish you well. Thanks for using our services and feel free to ask for more information and clarifications if need be.
