What major requirements are essential in a patient's requisition?

The inclusion of a patient's full name, type of specimen, and relevant clinical history on a requisition is essential for several reasons. The patient's full name is critical for accurate identification and ensures that the laboratory results are matched correctly to the individual, thus preventing potential errors in testing and treatment.

Specimen type is crucial as it guides the laboratory in processing the sample appropriately and selecting the right tests. Different specimens require specific handling, storage, and testing procedures. For example, blood specimens are processed differently than urine or tissue samples.

Relevant clinical history provides context for the laboratory staff about the reason for the test. This information can influence the interpretation of results. For instance, if a patient has a known condition, the lab can look for specific markers that may suggest a worsening of that condition or response to treatment.

While other options mention important information, they do not encompass the comprehensive requirements that are prioritized in a requisition where both identification and clinical reasoning are essential for accurate and effective laboratory work.
