What’s new

Version 2.0

A big release: a new Overview, interactive charts throughout and a new look. Here is everything that has changed since version 1.

A new Overview

  • The first page you see. Every laboratory’s QC health at a glance:
    • Lab Confidence and its most serious finding in one sentence.
    • A card each for Accuracy (CRMs), Precision (duplicates), Contamination (blanks) and Despatch coverage.
    • A Key Takeaway.
  • Finds the problems for you:
    • CRM bias, drift and trends for each analyte.
    • Duplicate precision against each check stage’s limit.
    • Blank exceedances.
    • Periods with no QC at all.
  • Current Risks and Worst analytes, worst first.
    • Investigate or View data opens the chart behind a finding.
    • The chart opens filtered to the despatches concerned.
  • Featured charts: the laboratory’s worst bias (CUSUM) and worst precision trend (RD Rolling Median).
  • Rules: set how the checks are judged. This covers precision limits by check stage, the analytes to assess and the minimum QC in a despatch. Your rules are remembered in your browser.

Interactive charts

  • Every chart is interactive:
    • Point at a result to see its details.
    • Click a legend item to hide or show it.
    • Open the chart full screen, or download it as an image or as the data behind it.
  • New charts:
    • Z-Score (in place of the Violin chart).
    • RD Rolling Median.
    • All Time Series.
    • Interactive CUSUM and EWMA.
  • Nelson 8 rules with a table of the rules broken. Click a rule in the table to highlight its points.
  • Clearer control bands:
    • Within the warning limits is green, between warning and action is amber, and beyond is red. Bands can be turned off.
    • The 3 SD action line is in red.
    • Shewhart charts show the median.
    • Colours are safe for colour-blind users.
  • Facet by check stage, with each panel’s own statistics.
  • “How this is calculated” under each chart: the method, worked through with that chart’s own numbers.
  • Corrected methods:
    • The CUSUM allowance.
    • EWMA control limits.
    • Thompson-Howarth precision scaled to one standard deviation.
    • Hyslop & White relative difference.
  • Charts fill the page width. A chart that can’t be drawn says why in its place, not in a pop-up.
  • Each QC type keeps its own filters and chart when you switch between them.

Getting your data in

  • Results as laboratories write them:
    • “<0.005” is read as half the detection limit.
    • “>x” is read as x.
    • Codes such as LNR or IS, and results of 0, are read as missing.
  • Dates in any usual form. A date in the future (a typo) is read as missing.
  • An import report on the Data tab lists anything in the file worth checking.
  • Large workbooks:
    • They are read a little at a time.
    • The largest file is 50 MB.
    • A sheet of blanks opens on Contamination.
  • The templates download includes the expected-fields guide and SQL views.
  • The demo data runs to November 2025.

Tables

  • Statistics tab: accuracy statistics with their formulas, titled with the laboratory, CRM, analyte and dates.
  • Data and Statistics tables wait for the filters to settle instead of redrawing at every step.
  • Dates are shown in your own format.

Look and help

  • A new dark design.
  • Help:
    • A “?” beside each area explains every part of it.
    • A short tour runs the first time you open Cloud QC.
  • What’s new: this page. The version you’re using is shown here and on the About page.
  • Feedback replaces Support.
  • Updated Terms and Conditions and Privacy Policy.

Removed

  • The Health Check tab: the Overview does its job.
  • The Links tab and the old Help tab.
  • The separate chart download button: use the menu on the chart.
