I now just take the view that if they want a retest in..... then after that time they have a retest.
ive had it a few times and 2nd time around the result is the same or better.. particularly in my early stages i had so many little things not right... i figured if anything was badly wrong they would want more than a retest in 1,2 or 3 months
as for the receptionist... there is a reason the are a receptionist and not a GP... and that is that they are not qualified.. even though many in my practice think they are as you battle to get a GP appointment
