CSols AqcTools™ Overview

The complete AQC software package

CSols AqcTools™ offers a wide range of integrated features so that it covers all of the capabiltes required to offer a complete laboratory AQC data management solutions to help meet ISO 17025 and 15189 requirements and including the following capabilities :

  • Allows users to dynamically display a range of interactive and annotated Analytical Quality Control (AQC) charts including Shewart/ Levey-Jennings, Probability and distribution charts
  • Manual or automated import of QC data from LIMS, Links for LIMS, instuments/analysers or middleware systems
  • Automated application of Westgard rules for exception handling, with inbuilt auditable investigations of limit and trend failures
  • Integrated F & t tests and measurement of uncertainty (MoU) calculations for limit reviews
  • Comprehensive range of reports
  • Access to a SQL report tool to provide customized reports

All intended to to reduce the time to assess and process your QC data compared to semi automatied methods using Excel, hence quickly identify potential failures, improve laboratory quality and reduce effort duting external audits.  Customers in the water, environmental, forencis, clinical, public health and industrial sectors conducting any chemical, biochemical, clinical or microbiological analysis will benefit from AqcTools.

AqcTools in Use

AqcTools provides a selection of ‘dynamic, interactive’ charts from the standard ‘individual plotted AQC points’ to charts that can use batch or daily means of data, for both current and historic data. Seen in the figure below data points that fail Westgard Limit Rules are colour coded (red – amber – green) to make them easy to identify with quick access to statistics such as mean, standard deviation, bias, % action and % warning failures. This allows users to quickly assess the performance of the analytical method.

Data Entry

QC data can be added to AqcTools in a number of ways from simple manual entry or by the use of a configurable template to match an individual labs processes, direct capture from the instruments (via CSols Links for LIMS instrument interfacing and integration product) or directly from your LIMS.

Integrated Investigation Forms

CSols AqcTools v2.6 - Investigation and Exception Reporting

AqcTools provides a paper-free mechanism for recording investigations and the remedial actions taken in the event of Rule failures with an electronic sign-off protocol.

Additionally, users can access information directly (‘one-click’) from the chart; which along with the comments functionality allows immediate access to all the actions taken which effect analytical performance. Consequently, all of this remains accessible against ALL historic data and is available for future investigations or any regulatory or customer audits.

Furthermore, the Incomplete Exceptions report provides an easy to use tracking system to monitor progress of current investigations. This includes hyperlink access to the charts and each individual investigation report. Also, these features reduce staff time and simplify both internal quality or management reviews.

Limit and Chart Review

AqcTools provides statistical tests such as F and t-tests required by accreditation bodies for both Limit Review and Chart Review. Consequently, comprised into one easy to interpret report, that uses a colour coded system to highlight any issues. Also, to aid  investigations plots and reports are available which indicate whether data is normally distributed.
