predestination - previous determination as if by destiny or fate. doom, doomsday, end of the world, day of reckoning - an unpleasant or disastrous destiny; everyone was aware of the approaching doom but was helpless to avoid it; that's unfortunate but it isn't the end of the world.
That is 2 1/2 hours! Average is 3 hours now from start to finish. THEN we have to wait for the scan to be sent to the radiologist, and when he/she calls back, we can dispo the patient. I can't believe that every CT done in this country for a possible appy or whatever takes over 3 hours.
Previously, clinicians often had to wait an average of 6 hours with the lower-sensitivity, lower-precision cTn assays to see a conclusive increase in plasma cTn levels after the first troponin measurement, but today's high-sensitivity cTn tests that are separated by a mere 2 to 3 hours can be highly informative.
