What is a Laboratory Requisition?

A laboratory requisition is a formal request made by a healthcare provider for specific tests or analyses to be conducted on samples from a patient. This document provides essential information necessary for the laboratory to perform the requested tests accurately and efficiently.Typically, a laboratory requisition includes:

• Patient's details (name, age, gender, and identification)
• Type of specimen (blood, urine, tissue, etc.)
• Tests to be performed (specific lab tests requested)
• Clinical information (reason for tests, symptoms, medical history)

Importance of Laboratory Requisition in Healthcare

Laboratory requisitions play a critical role in patient care by facilitating accurate and efficient laboratory testing. They ensure that healthcare providers obtain the necessary information to guide diagnosis and treatment.Some key reasons why laboratory requisitions are essential include:

• Clarity and Accuracy: The requisition form details the exact tests required, reducing the risk of misunderstandings between the provider and laboratory staff.
• Quality Control: Providing comprehensive patient information helps ensure that tests are interpreted correctly by the laboratory, leading to more reliable results.
• Efficiency: Having all necessary information on the requisition speeds up the sample processing time and decreases the chances of requiring repeat tests.
• Legal Protection: A well-documented requisition can serve as important legal documentation, offering a record of the healthcare provider's ordering behavior and rationale for tests.

How to Complete a Laboratory Requisition Form

Completing a laboratory requisition form accurately is vital for ensuring that the laboratory has all necessary information required to process the tests. Below are the steps to follow for filling out the form:

• Patient Information: Include the patient's full name, date of birth, and gender. This helps in identifying the sample correctly.
• Ordering Provider: Enter the name and contact information of the healthcare provider issuing the requisition. This ensures the laboratory can reach the provider if further information is necessary.
• Tests Requested: Clearly specify the tests to be performed. It is essential to include any test codes if applicable.
• Clinical History: Provide relevant clinical information, such as symptoms or prior conditions, to assist the lab in making informed decisions regarding the analysis.
• Specimen Type: Identify the type of specimen being submitted (e.g., blood, urine, swab) and ensure the collection container is appropriately labeled.
• Date and Signature: Finally, date and sign the form to validate the request. An unsigned requisition may delay processing.

Common Scenarios for Using Laboratory Requisition

Laboratory requisitions are commonly utilized in various clinical scenarios. Understanding when and why to use them enhances the quality of patient care. Below are some common situations in which a laboratory requisition is necessary:

• Routine Check-Ups: During annual physicals or wellness visits, patients may require baseline laboratory tests.
• Diagnosis of Conditions: When a healthcare provider suspects a condition such as diabetes, tests like a glucose level need to be requested through a requisition.
• Monitoring Treatment: For patients undergoing treatment for conditions like hypertension, regular blood tests are essential to monitor medication effectiveness.
• Specialized Testing: In cases where specific and advanced testing is required (like genetic testing), a requisition is mandatory to guide labs on the unique requirements.
• Emergency Situations: In acute care scenarios where urgent tests are needed, an accurately filled requisition aids in the prompt delivery of critical results.

Causes of Laboratory Requisition Errors

Common Mistakes in Laboratory Requisition Technique

Errors in laboratory requisitions can have significant consequences for patient care. Here are some common mistakes that can lead to inaccuracies:

• Inadequate Patient Information: Missing or incorrect patient identifiers can result in mismatched samples.
• Ambiguous Test Requests: Using vague language or abbreviations can confuse laboratory staff regarding the tests needed.
• Failure to Provide Clinical Context: Not including relevant medical history or symptoms can hinder the laboratory's ability to interpret results accurately.
• Incorrect Specimen Labeling: Labels that are smeared, incomplete, or incorrectly filled out can lead to processing issues or sample rejection.
• Neglecting to Sign the Requisition: An unsigned requisition can delay testing, as laboratory staff may not have the authority to proceed without proper endorsement.

How to Avoid Laboratory Requisition Errors

To minimize errors in laboratory requisitions, following best practices is essential:

• Double-Check Patient Information: Always verify the patient's details before submitting the requisition.
• Use Clear and Specific Language: Avoid medical jargon or abbreviations that may not be universally understood within laboratories.
• Provide Comprehensive Clinical Information: Include pertinent medical history and symptoms to assist in accurate test interpretation.
• Label Specimens Immediately: Ensure that the specimen is labeled at the time of collection with the correct patient details.
• Review Requisitions Before Signing: Always review the filled form for completeness and accuracy prior to signing and submission.
