Preparation Steps
1. Gather Necessary Equipment and Supplies:
- Advia Centaur XP analyzer
- Reagents and controls specific to the test being performed
- Pipettes and tips
- Sample tubes
- Personal protective equipment (PPE)
2. Review Test Protocols:
- Familiarize yourself with the test instructions and specifications provided by the manufacturer.
- Ensure that all reagents are within their expiration dates and properly stored.
3. Calibrate the System:
- Before conducting manual tests, ensure that the analyzer is calibrated according to manufacturer guidelines.
Sample Preparation
- Collect Samples: Obtain patient samples using proper phlebotomy techniques.
- Label Samples: Clearly label each sample with the patient's information and the date of collection.
- Centrifuge Samples (if required): If the test requires serum or plasma, centrifuge the samples to separate the components.
Performing the Manual Test
1. Set Up Controls:
- Run quality control samples to ensure the accuracy of the test system before proceeding with patient samples.
2. Add Reagents:
- Follow the manufacturer's instructions for adding reagents to the sample. This typically involves pipetting specific volumes into designated wells or tubes.
3. Incubation:
- Allow the samples to incubate for the specified amount of time, as indicated in the test protocol.
4. Detection:
- Use the Advia Centaur XP analyzer to detect the signals generated by the reactions. This may involve measuring luminescence or other optical properties.
5. Data Interpretation:
- Analyze the results using the software interface, which will provide quantitative or qualitative data based on the test performed.
Common Manual Tests Conducted on Advia Centaur XP
While the Advia Centaur XP is capable of automating many tests, certain manual tests are frequently performed in conjunction with its capabilities. Some common manual tests include:
- Thyroid Function Tests: Such as TSH, T3, and T4, which may require manual confirmation for abnormal results.
- Tumor Markers: Tests for specific cancer markers may necessitate manual verification to ensure accuracy.
- Infectious Disease Tests: Certain serological tests for infectious agents may be performed manually to confirm automated results.
Documentation and Reporting
- Record Keeping: It is essential to document all manual test procedures, including reagent lot numbers, calibration data, and quality control results.
- Reporting Results: Results should be reported accurately and in a timely manner, following laboratory protocols for communication with healthcare providers.
