Question

which of the following could cause a specimen to be rejected from the lab? a fasting lab was drawn on a patient who ate breakfast. a handwritten lab requisition was sent with the specimen. the urine specimen was left at room temperature in a urine collection cup for 4 hr. the name on the specimen label does not match the lab requisition.

Explanation:

In laboratory - testing, specimen identification accuracy is crucial. A mismatch between the specimen label and the lab requisition can lead to incorrect patient - test associations, which is a major reason for specimen rejection. While the other options (fasting non - compliance, handwritten requisition, and urine specimen storage time) may have implications, misidentification is a more critical issue.

Answer:

The name on the specimen label does not match the lab requisition.
