<prompt> Preferred method for determining microalbuminuria is:Urinary dipsticks24 hour urinary protein collectionUrinary AC Ratio in a spot voided sampleUrinary AC Ratio in a 24 hour collection  <response>: Answer is C Urinary AC Ratio in a spot voided sample The preferred method to establish microalbuminuria is to determine Albuma Creatinine Ratio AC Ratio in a spot voided urine sample. The presence of albumin in the urine in the range of microalbuminuria is best determined by a urinary A C Ratio in a spot voided sample.
