Which of the following is NOT typically included in a requisition for lab tests?

In a requisition for lab tests, the ordering provider's details, patient demographics, and diagnosis code are essential components typically included. These elements are crucial for ensuring that the lab has all the necessary information to process the test accurately and efficiently.

The ordering provider's details are important so that the lab can contact the provider if there are any questions or issues regarding the test. Patient demographics help the lab verify the identity of the patient and maintain accurate records. Including a diagnosis code is critical because it provides context for the tests being ordered, helping the laboratory understand the medical rationale behind the request.

Specific testing preferences, while they may be considered in some cases, are not standard components of a lab requisition. This is because lab tests usually have established protocols and guidelines that dictate how they should be performed. It isn't typical for providers to specify personal preferences regarding the testing methods or processes in a requisition. Therefore, this choice does not align with the fundamental information required in a lab requisition.
