Answer to Question 1

ANS: D
Reference ranges should be determined by evaluating a group of perhaps as many as 120 normal healthy people for the same analyte. If the analyte differs in different groups, based on data such as age and sex, then it must be determined for each group if at all possible.

Answer to Question 2

ANS: D
This result is inaccurate compared with the first because it is significantly different. Precision is not known, because multiple results are needed to determine precision; in addition, precision must be determined using the same instrument, not between instruments. Because it is not accurate, it cannot be reported.
