What is BS EN ISO 18113-1:2012?

BS EN ISO 18113-1:2012 is a technical standard that specifies the general requirements and test methods for in vitro diagnostic (IVD) medical devices used for infection testing. This standard addresses the need for accurate and reliable tests to diagnose infectious diseases, allowing healthcare professionals to make informed decisions about patient care.

Requirements for IVD Medical Devices

This standard sets out the essential requirements that IVD medical devices must meet to ensure their safety and effectiveness. It covers a wide range of aspects, including design, performance, labeling, and documentation. Compliance with BS EN ISO 18113-1:2012 is crucial for manufacturers to demonstrate that their products are of high quality and suitable for clinical use.

One key requirement outlined in this standard is the need for analytical sensitivity and specificity. Analytical sensitivity refers to the ability of the device to detect even small amounts of the target analyte in a sample, ensuring accurate diagnosis. Specificity, on the other hand, ensures that the device only reacts to the intended target and does not produce false positive results.

Test Methods for Validation

The validation of IVD medical devices is an important aspect of ensuring their reliability and accuracy. BS EN ISO 18113-1:2012 provides guidance on various test methods that manufacturers can use to validate their devices.

For example, one commonly used test method is the comparison to a reference method. This involves testing a set of known samples using both the device under evaluation and a well-established reference method. The results obtained from both methods are then compared to assess the accuracy and agreement between them.

Another important test method outlined in this standard is the assessment of interference. Interference refers to any substance or factor that may affect the test results. Manufacturers need to evaluate and demonstrate that their devices are not affected by common interfering substances or conditions, ensuring accurate and reliable performance.

Conclusion

BS EN ISO 18113-1:2012 plays a vital role in setting the requirements and test methods for IVD medical devices used in infection testing. Compliance with this standard ensures that these devices are safe, effective, and provide reliable results. Healthcare professionals can rely on these devices to accurately diagnose infectious diseases, leading to appropriate treatment and improved patient outcomes.

Manufacturers must carefully follow the guidelines set out in BS EN ISO 18113-1:2012 during the design, development, and manufacturing of IVD medical devices. Proper validation using the recommended test methods is crucial to demonstrating the accuracy and reliability of these devices. By adhering to this standard, manufacturers contribute to the overall quality and effectiveness of in vitro diagnostic tests, benefiting both healthcare providers and patients alike.
