"Efficient appointment but no results"

The first thing that concerned me was why was the appointment in Daventry. I live in Northampton. I was concerned about driving there and trying to find the right place. Anyway my son drove me and came in with me. 

It is a great little medical centre and the people were lovely, the appointment was carried out almost as soon as I arrived(a little early) was quick and efficient. 

I asked how do I get the result and they said from your GP. They will get the results in 2-3 weeks. That was around 6-8 weeks ago and they still haven't received them. It is a worry because it is the heart. There just doesn't seem to be any sense of urgency . I had already waited months for the appointment
