There may be various reasons for you as a family to be asked/required to book a test. If you have a child at school, the school may refuse to let your child return to school without a negative result, you may have an appointment for an operation so the hospital will require you to have a negative result before your operation goes ahead. these are two instances that I have had to attend a Test Center. Other reasons are more obvious, having one or more of the symptoms listed by the NHS/Gov.
Just because you have a Test Center in your village/town does not mean that you will be given an appointment there when you apply for the appointment. If you apply on line you can spend hours just filling the same form over and over and click submit only to be told there are no appointments available, or, you may be offered one in Bootle in 20 minutes or Stoke in 1 hour as happened to me. I spent from 9am on a Tuesday until 6pm on the computer doing this but no appointment. I even rang 119 and spent 1 hour and 20 minutes on the phone only to find out that all they do is exactly the same as you, fill in the same form and press submit. I think 119 is for people who cannot spend a lot of time searching themselves or don't have a computer.
I eventually gave up on the Tuesday and started again on the Wednesday from 6am. At 2pm I went back on the site and about 50 appointments suddenly appeared with about 20 at Brinnington, one of which I got for an hour later which we attended. This was for my son so that he could return back to school. The site was empty, all of the staff were just waiting around waiting for patients. Result negative, son back in school.
This was a couple of months ago so hopefully the system has improved vastly. It is no good booking a drive through test if you don't have transport as they won't let you on the site. The test is simple and although uncomfortable not painful.
The more Test Centers they have the quicker you can get a test done, getting the result took me 32 hours, I have heard that some people wait a lot longer than that, this will improve as testing methods and results testing will get better.
The point I'm trying to get across is that we are all in this together and although it may inconvenience some people as to where these Test Centers are located it is for the benefit of us all. If people do not apply for an appointment unless they are requested to/or show any of the symptoms then i cannot see massive queues of cars or people appearing in Marple.
Haven't typed this much since retiring 10 years ago, sorry if offended anybody, rant over!!!!
