What additional information should be documented on a requisition form?

The documentation of a patient's history related to the test or procedure performed is crucial for several reasons. Firstly, it provides context that can influence interpreting test results, as certain medical conditions, medications, or previous test results may affect outcomes. This history helps technicians and healthcare providers understand the patient's background and any factors that may complicate the analysis of the specimen.

Additionally, accurate documentation of a patient’s history can facilitate more effective communication among the medical team. It assists in ensuring that the test results are aligned with the clinical scenario, potentially guiding treatment decisions based on the patient's past medical events or current health status.

While the other options include important details such as the type of specimen collected, test being performed, patient identification, and the practitioner’s signature, the patient's history adds a layer of clinical insight that can be essential for comprehensive care. It underscores the importance of personalized medicine, where treatment and analysis are tailored to individual patient histories. Therefore, documenting patient history is a critical component of the requisition form.
