History of versions of MultiQC

Version 5.0

• A new way to verify the reportable range, a highly sophisticated mathematical tool, however so easy to understand and to use.
• New management of the events that occur in each analytical method (see user manual section 5).
• Improvement in the management of logins (see user manual section 12)
• Small bug fixes

Version 5.1

• A tool for analytical method comparison. Like many other ones it implements ordinary linear regression, Deming regression, Passing-Bablok regression and a modified Bland-Altman difference plot. But for the first time, the limit between commutable and non commutable methods is based on medically allowed error instead of statistical significance.

Version 5.1.2

• Calibrations are frequent causes of QC upset. It is most useful to be aware of the time of calibrations and of reagent blanks to be able to understand and explain numerous unexpected shifts of QC curves. This version of MultiQC can automatically draw calibration flags on the QC charts when connected to an analyzer that outputs calibration signals.

Version 5.2.0

• There is no science without repeatability. Verifying repeatability of analytical methods is the first step of troubleshooting out-of-control situations or bad EQA returns. This version of MultiQC can automatically process and archive repeatability data transmitted by analyzers. These data are simply recognized thanks to a reserved identifier.

Version 5.2.2

• Small bugs fixes and additional buttons to scroll dates

Version 5.3.1

• Additional control mode named "Retained CV" to be used when switching to a new batch of control materials : CVs (and correlations between levels) from the older batch are retained for the newer batch whilst means are kept floating to get charts self-centering on the new targets.
• Reference pools can be made of several unconnected intervals of dates
• Offsetting targets replaced by "Manufacturer targets" displayed as dashed lines on the plots.
• Improvement of "cloned analytes": Events and EQA data are automatically updated when a change occurs in the original analyte.
• Cosmetical changes and bug fixes.

Version 5.3.2

• Nothing changed but registration keys that can be immediately delivered by payment services. The former key file to be stored to the installation folder of MultiQC is replaced by a [name+code] key to be typed in a registration dialog.

Version 5.4.0

• Monitoring the time of QC.
