As an integral part of laboratory testing quality assurance programs, peer comparison plays a crucial role. It entails comparing test results between laboratories to detect and rectify any systematic errors or biases that may exist.

LabLink xL provides comparison of the accuracy and precision of analytical processes between laboratories and peer groups.


Perform all your daily QC activities inside LabLink xL with interactive charts and graphs. Generate these reports on-demand or set the system to automatically generate reports e.g. at the beginning of each month for every active configured QC control lot. The generated reports can be automatically emailed to your inbox. Alternatively, choose to receive a notification when the reports are ready for download.

Product Specifications
Percentage Bias – Percentage difference between your observed test results and your lab’s target mean
Coefficient of Variation (CVI) – Compares your lab’s CV to your target CV to evaluate precision with respect to your chosen target
Standard Deviation Index (SDI) – Compares your lab’s mean to your target mean to evaluate accuracy with respect to your chosen target
Sigma – Indicates how much your data varies from the total allowable error limit by calculating the number of standard deviations in a given test system that fit within your chosen quality goals

Z Score – Measures how many standard deviations away an individual QC result is from the target mean

No installation requirements: LabLink xL is a web-based solution so any PC with web access can be used
Available in 15+ languages

Manual data entry or csv file data transfer. Download data direct from the Optilite system to a secure USB device and upload to LabLink xL
