Thanks for posting,
Well I do not personally understand why your test results should be hidden from you and only ask to be redone after 1 month. Fasting blood tests could be done when testing for sugar, cholesterol
, uric acid and other diet dependent tests. It is mostly done for glycemia
(to determine if diabetic or not). If you had groin pain radiating to the kidneys, I personally would have requested for a urine analysis, abdominal scan (especially looking at the kidneys + bladders + ureters etc).
Usually when results are asked to be done after it is for a confirmation of a test conducted earlier. Usually after a while if a test value was high or positive, after a while it could normalize or become negative. Surely that is why they ask to do it again after a month.
Hope this helps
