Five milliliters of 5% alcohol are added to 5 mL of urine. Two milliliters of this solution is diluted to 50 mL with water, and 5 mL of this are used for analysis. How many milliliters of urine are in the analysis sample? You are doing a procedure that calls for 5 mL of undiluted urine. You use 3 mL of a 1/5 dilution of urine instead. The answer obtained is 50 mg/dL. What result should be reported? A procedure...
