There are a variety of RIQAS reports designed to enable quick and easy identification of any trends or test system issues. The standard quantitative report is provided in a user-friendly, one page per parameter format allowing a visual, at-a-glance assessment of performance. The standard quantitative report is split into several easy to interpret subsections each designed to save valuable laboratory time.
You can explore each of the report sections using the table below. Don’t forget, to enlarge the image, simply click on it.
RIQAS EQA Reports
RIQAS Reports Features
Performance data is presented in a simple one page format for each analyte. Each one page report comprises seven sub-reports providing a statistical and graphical representation of laboratory performance.

The text section provides a statistical breakdown of results by all methods, your method and instrument group. The Mean, CV% and Uncertainty or Measurement is presented for each comparison group.
Your laboratory’s result is compared to the Mean for Comparison (usually the instrument group Mean). Also included are the RIQAS performance indicators; SDI, Target Score and %Deviation.
Acceptable performance criteria:
- SDI <2
- Target Score >50
The defined acceptable limits default to the RIQAS TDPA values but may be based on CLIA, biological variation or country specific limits.
Performance goals based on Biological Variation are also stated within the text section for information purposes.

The histogram chart provides an overview of how your laboratory’s result compares to the all method group, your method group and your instrument group. Your result is represented by a black triangle; the closer to the centre the better.
The chart is intended to provide a quick visualisation of performance compared to other method groups and can be used to identify any potential bias.

The Levey-Jennings chart plots the last 20 SDI’s and is extremely useful for monitoring EQA performance over time, allowing quick and easy identification of any trends or bias. The chart is colour coded making interpretation simple and easy; results that fall in the white area are excellent and those in the red area unacceptable.

The Target Score (TS) chart is a unique chart which displays your laboratory’s last 20 target scores delivering an instant, visual indication of performance. The TS chart is conveniently colour coded for even easier performance assessment, a TS >50 is acceptable. The TS is a numerical index relating your %Deviation from the mean to a Target Deviation for Performance Assessment (TDPA).

The %Deviation by sample chart displays the %Deviation for the last 20 EQA samples enabling identification of trends and shifts in performance. Similar to the other charts on the RIQAS report, the %Deviation by sample chart is shaded to indicate the limit of acceptable performance. A black dot within the white section of the chart will represent results with a %Deviation within your acceptable limits of performance; a black dot within the red section of the chart will represent results with a %Deviation outside your acceptable limits of performance. %Deviations are not influenced by the performance of your peers, as seen with the standard deviation index (SDI) and therefore is a better indicator of individual performance.

The %Deviation by concentration chart enables easy detection of possible concentration related biases. Unlike the other charts provided on the report, the %Deviation by concentration chart displays the concentration range of the previous 20 samples along the bottom of the chart.
Using this scale along with the percentage deviation, you are provided with a rapid assessment of your %Deviation in relation to the concentration of the:
• Current sample (represented by a square)
• Your 19 previous results (represented by circles)
This chart provides an easy interpretation of potential positive or negative biases at high or low concentrations, or whether a particular sample is a random outlier.

The Multi Method Stat Section provides you with an easy way of assessing the performance of the other methods used to analyse the parameter. This is useful when your laboratory plans to change the analytical method used for the parameter.

Located at the back of the standard quantitative report, our quick reference summary page details the performance for each registered parameter in the programme.
Within the performance column, RIQAS provides an effortless method of assessing the performance of each parameter within the sample distribution. When a red triangle appears next to the parameter, this indicates that all performance indicators (SDI, TS and %DEV) have exceeded the performance criteria.
The performance indicator limits for each parameter are exceeded when your result produces:
• An SDI greater than +/- 2 standard deviations.
• A Target Score less than 50 (only when Target Scoring is available)
• A %Deviation greater than your set acceptable limits of performance.

A summary CSV file is available on request to all participating laboratories. The report provides a summary of all statistics, acceptable limits and performance indicators as a .csv file for each sample in the cycle.
A retrospective statistics summary is also available, four weeks after the final submission date for parameters where a result was not submitted on time.
RIQAS is the largest international External Quality Assessment (EQA)/ Proficiency Testing (PT) scheme, there are currently more than 55,000 participants in 134 countries. World renowned for reducing the number of individual programmes required by even the most demanding laboratories, RIQAS covers 360 parameters across 37 flexible multi-parameter programmes.

In a QC survey conducted this year, Sten Westgard reached out to more than 45,000 laboratory professionals to gain a comprehensive view of the world’s Quality Control practices. It was one of the largest surveys that have been conducted and shared publicly.
Read on as we take a summarised look at our favourite bits.
Setting control Limits
Most labs are using their actual performance to set their mean and SD, however, a large percentage of labs still use manufacturer’s ranges, peer group ranges, and other non-individual sources for SD. These ranges can typically be set wider than they would if the ranges were based on their actual mean and SD. This can result in labs releasing incorrect patient results.
Laboratories were asked if they used 2 SD control limits on all tests and it was found that a majority use 2 SD. The strict use of 2 SD can generate a high level of false rejections (9% for two controls and higher for three). This causes a high level of out-of-control events; the use of QC multi-rules is recommended.
The types of Controls used by labs
More than 60% of labs were found to be using manufacturer controls, the drawbacks of which are well known. The latest ISO standards strongly encourage the use of independent / third-party controls. Westgard speculates that this will become a mandatory requirement in the next version of ISO 15189.
Frequency of QC
The first question about frequency asked how often labs ran QC during a run. Respondents reported how often they schedule QC in their labs. Around half only run QC at the beginning of a run with labs running it throughout the day coming in close second. A small proportion of labs reported running QC at both the beginning and the end of a run.
The final, least popular option involves spacing out QC based on test volume, the most scientific method determining how many patient samples can be run between controls without raising the risk of unacceptable results.
The next question asked about the overall frequency of QC. Most labs are meeting the once-a-day minimum standard for CLIA regulations.
“QC frequency remains primarily based on the rotational speed of the earth, not driven by needs of the clinician and patient.” – Sten Westgard
QC Frequency Influences
Regulator and accreditation requirements lead the way in influencing the frequency of QC with manufacturer recommendations, and professional judgement following close behind. Only a quarter of labs use the volume of testing to guide their QC frequency and one in six look to EP23 or IQCP for guidance.
Most labs are using on-board instrument informatics to support their QC charting, followed by LIS charting programs, and peer group software.
Of significance is the number of labs using Excel spreadsheets as their primary QC tool as well as standalone QC programs or even manual graph paper. This could be due to varying technological capabilities where some locations may not have access to, or the funds to afford, informatics.
A combined third of labs are out-of-control every day. In some labs this could be the result of running such a high volume of controls that false rejections are inevitable. However, rationalising in this way can lead to ‘alert fatigue’, where users begin to ignore alert flags and stop troubleshooting.
More than a quarter of labs have an out-of-control flag every few days while another roughly one in six have just one per week. A small number of labs report having few QC flags.
Managing QC Costs
Finally, laboratories were asked about the steps they take to manage QC costs. 60% claimed that they take no steps to manage costs. One in six reduced QC frequency, one in eight switched to cheaper controls, while, worryingly, almost one in ten changed their QC rules or widened limits.
Westgard’s Global QC Survey suggests there exists many inefficient implementations of Quality Control, with plenty of room for improvement. The current state of QC is, like many aspects of healthcare, unsustainable. Labs must adopt better approaches or risk their continuing feasibility, or worse, their patient’s results.

Global health diagnostics provider Randox has maintained its status as a significant competitor in the Asian market by participating in the NCML Exhibition in Hangzhou. The NCLM is the largest laboratory equipment exhibition in China dedicated to the advancement of diagnostic equipment and is an annual staple of the country’s top medical equipment firms. Also attracting some of China’s top clinical science talents, the exhibit was held in the capital of China’s Zhejiang province on 20th September.
In-vitro diagnostic (IVD) equipment, which enables diagnosis and monitoring of samples taken from the body, was the sole focus of the exhibition but an essential aspect of the IVD process is Quality Control. The Quality Control Market is a lucrative one and continues to grow – estimated to be worth $1.04 billion by 2022.
Over many years, Randox has developed the largest global EQA (External Quality Assurance) scheme available on the market, RIQAS, which offers laboratories around the world assurance that the results they are releasing are accurate and reliable. With just under 40, 000 participants in 132 countries and 32 flexible programmes, it is little wonder that the global health technology giant is predicting huge growth in Chinese territories.
Randox has been involved in trade in China for over 20 years and has been making significant strides in the Asian market recently through a strategic Chinese market expansion launch in December 2016. This expansion has included the securing of distributors across four of the largest provinces in China and partnerships with hospitals in Guangzhou, Shanghai and Wuhan.
Preceding the NCML Exhibition, in February 2017, Randox launched a major recruitment drive to hire Mandarin-speaking graduates in Northern Ireland who could join the sales, marketing and scientific teams in China. The company, which employs over 1,400 workers worldwide, was supported by Ulster University and its Confucius Institution in this recruitment campaign.
Ying Zhu, Sales Manager for Randox Laboratories in China, commented on the success Randox has seen in China over the last ten months;
“China is one of our key markets and we were delighted to showcase our capabilities at China’s largest IVD equipment exhibition recently. Randox in China has been growing from strength to strength in the last year, building on a solid foundation laid in 20 years of trade with the country. We continue to increase our presence in the Asian market thanks to increased output from our innovative R&D programmes, and enhanced manufacturing capabilities, including new facilities at the Randox Science Park, our new headquarters in Antrim. These infrastructural developments have resulted in an increasing range of products which we can now offer to growing and dynamic markets such as China. This increasing range of products coupled with a growing market presence has significantly increased our business penetration and subsequent support to customers.”
Margaret Fick, RIQAS Scientist added;
“At our most recent training conference in China, we were very pleased to host several of our newly acquired hospital partners who presented to our audience how many laboratories have benefitted from our Randox Quality Control products. The testimonials from high profile individuals who have experienced the quality, efficiency and reliability of our products is accelerating our growth across China.

From April 23rd to April 29th we are celebrating Medical Laboratory Professionals Week! This is a week dedicated to raising awareness for those who work in a laboratory & the hard work that goes unnoticed every day in laboratories around the world.
Have you ever wondered what happens between submitting your patient sample and receiving your results? Have you ever wondered who conducts the detailed laboratory testing for your annual check-up such as cholesterol and glucose levels? Or who analyses these results? The answer, a Medical Laboratory Professional (MLP). MLP’s provide up to 70% of the medical laboratory results for physicians and others to make informed decisions about a patient’s diagnosis and aftercare treatment plan. The work that laboratory professionals do each and every day is integral to providing excellent patient care. They perform and interpret billions of laboratory tests every year.
Providing accurate and reliable test results is of the utmost importance for laboratory professionals and also for us at Randox. With a passion for Quality Control, and with more than 30 years’ experience developing Laboratory QC for the in vitro diagnostics market, we believe in producing high quality material designed to streamline procedures, whilst reducing costs in laboratories of all sizes and budgets. These qualities have been reflected in our Acusera true third party quality controls, Acusera 24.7 interlaboratory data management software, Acusera Verify Calibration Verification material and RIQAS, the largest international EQA scheme.
Randox Quality Control would like to take this opportunity to thank all the laboratory professionals around the world and especially our own laboratory staff – you truly are the “Unsung Heroes of Healthcare”.
