Does your clinic test for heartworms and do you have to make an appointment?

Yes you have to make an appointment my advice would be called them first thing in the morning or late in the afternoon and very good location highly recommend it

Please check website for hours it's walk in for vaccines and testing but only during certain hours

They do offer tests I believe, I would suggest an appointment because they are very busy usually. Their website has all the services they provide as well as a way to make appointments.
