No rest!!

I went for a covid test yesterday, Tuesday 30 November at Lancet mall@reds. My appointment was at 10.30am. Ithe doc assured me I would get an sms with my result that evening. It is now 17.34 on Wenesday 1 Dec and i still have no result. I am obviously isolating buy are we expecting to take off work for 3 days and possibly have a negative result? I can see how this virus is spreading because I am tempted to just continue my life. I am trying to be responsible as I had mild symptoms but it could also be a common cold. How long are we supposed to put our lives on hold while waiting for a result? I went onto the Lancrt app. It was last updated 30 Nov 2.q3am. I need better service
