Letter after blood tests

I had full bloods taken a week ago at the GP.
Reason for the test is Im getting intermittent pains in abdomen area. Not had it for a week now though.

I received letter from GP yesterday saying.
Further to your recent blood test. Your result are now back. Dr would like to speak to you to discuss the results in a routine consultation. To arrange an appointment please contact the surgery.

As its the weekend I’m a bit worried it could be serious. Has anyone else received a simular letter after blood tests?

Thanks
