Quizplus · Accepted Answer

The high levels of ascorbic acid in the specimen, likely due to megavitamin supplementation, can cause false negative results for glucose and positive results for leukocyte esterase. This is because ascorbic acid can interfere with the chemical reactions used to measure these substances, leading to inaccurate results. The other options listed (dilute specimen, specimen color, and specimen clarity) are not as likely to cause discrepancies in the chemical and microscopic results.
