Correct Answer is C
Explanation
A. Urine specimen volume is 6 mL: A volume of 6 mL is generally sufficient for routine urinalysis, so this would not cause rejection.
B. Urine specimen temperature is 23° C (73.4° F): This temperature is within an acceptable range for a urine specimen that has been properly stored, so it would not cause rejection.
C. Urine specimen container is missing a preservative. Missing a preservative in the container can compromise the integrity of the specimen, leading to rejection.
D. Urine specimen is amber and turbid: Amber color and turbidity may indicate an abnormality, but they are not causes for specimen rejection in routine urinalysis.
