Final answer:
The item not included on a laboratory requisition form is 'test results', which are reported separately after the test has been conducted.
Step-by-step explanation:
The item not located on a laboratory requisition form is test results. These forms contain information essential for sample identification and processing, including the patient's name, date of birth, and the test requested. The purpose of this form is to communicate the physician's test orders to the laboratory personnel. Once the test is conducted, results are typically reported in a separate document. It is important that the nurse verifies that all pertinent information, such as the patient's name and the name of the procedure, is accurately recorded, and checks whether there are any issues such as incorrect labeling or equipment problems that could affect the quality and reliability of the test results.
