Whole blood is left at room temperature for six hours before separation, with no glycolysis inhibitor. What is the expected effect?
1Glucose is falsely increased
2Glucose is falsely decreased✓ 정답
3Glucose is unaffected
4Only potassium is affected
해설
Red cells and leukocytes continue to consume glucose, so the glucose concentration falls progressively at room temperature at a well-described hourly rate. This is why the specimen must be separated promptly or collected in a tube containing a glycolysis inhibitor.
