RIQAS Urinalysis Report

RIQAS Urinalysis reports have been designed specifically for participants of the RIQAS Urinalysis programme (RQ9138). Report features include;

  • Scoring system
  • Ability to rate performance and visualise historical performance data
  • Visual representation of performance
  • Peer group comparison levels

To find out more on the range of features available with the report, see the table below.


The Urinalysis Report scoring system, scores participants based on a spread of results over each category and how far a participant is away from the consensus, which is referred to as the Target Category.

The score calculated is based on how close to the target category a participant’s result falls. A score of 0 refers to a result which falls within the target category and therefore, the comment “acceptable” will be given. A laboratory’s performance is described as being acceptable or unacceptable based on this calculated score.

A laboratory must achieve a score of between -6 and +6 for their performance to be deemed acceptable. Scores can fall between the values of -10 and +8.

  1. If a participant’s result matches the target category then they will receive the score of 0 and the comment “acceptable” given.
  2. Where a participant returns a negative result and the target category is positive (category 9), the participant score will be -10. The comment “unacceptable” will be given.
  3. Where a participant returns a positive result (category 9) and the target category is negative, the participant score will be +8 and the comment “unacceptable” given.

(Click to enlarge)

Current Sample

The score achieved for the current reported sample together with the associated comment of acceptable, unacceptable or borderline will be listed in the comments box located towards the top of the results page for each registered parameter. The percentage (%) of results from the selected peer group which fall within the target category are also stated.

Potential Historical Information

The number of correct scores (i.e. scores of 0) that have been submitted in the last “n” samples, up to a maximum of 6 previous samples. The number of acceptable assessments that have been submitted in the last “n” samples, up to a maximum of 6 previous samples.

(Click to enlarge)

Charting of Current & Historical Information

Results of scoring for each sample are displayed on a Levey-Jennings style chart with “0” score in the middle and scoring categories positioned on either side for 2, 4, 6, 8 and 10. The chart is shaded into bands depending on the scores.

Acceptable scores (0-6) have no shading, Borderline scores (6-8) have light red shading and unacceptable scores (8-10) are shaded a darker red.

Scores for each of the last 12 samples are plotted against the appropriate sample number and the chart also indicates whether the participant’s reported result category is higher or lower than the target category.

The target categories are stated along the top of the chart and if there are no target categories due to a lack of numbers then an “X” is plotted to show that a result has been submitted but could not be scored.

Reporting – Summary Page

The summary page at the end of the report lists all of the parameters that a participant has registered for.

For each parameter the following information is stated:

  1. Target Category, which is dependent on the unit registered
  2. The result which has returned by the participant
  3. The score achieved for the current sample
  4. The comment of Acceptable / Unacceptable / Borderline
  5. Where the comment is “Unacceptable” it is highlighted in bold italics and underlined
  6. The number of “Acceptable” assessments that have been achieved over the previous 6 samples

RIQAS Urine Toxicology Report

A dedicated report is provided for the Urine Toxicology programme. The report is divided into two subsections; the screening (qualitative) and the quantitative section, allowing for visual performance assessment at-a-glance.


Your laboratory’s result is displayed along with the correct response. A visual chart is also provided displaying performance of the last 20 samples. A breakdown of the screening results submitted by other laboratories in your method group and all method groups for the current sample is also provided at a variety of cut-offs. A further breakdown is provided for various methods at your specific cut-off.

(Click to enlarge)

The Quantitative section of the Urine Toxicology report is further broken down into a text section comparing your laboratory’s performance to the mean for comparison, a Histogram chart indicating your laboratory’s performance in relation to the method group and the all method group and a multi-method section highlighting the performance of other methods.

RIQAS Instrument Group Report

All RIQAS participants are entitled to register up to five separate instruments per programme at no extra cost.

Individual reports for each instrument are supplied as normal in addition to a complimentary instrument group report allowing the performance of each instrument to be uniquely compared and assessed easily.


The multi-instrument group report displays the %Deviation for the last 10 samples along with the RM%Dev across all registered laboratory instruments. The %Dev for each instrument is plotted on a user-friendly, colour coded chart for instant identification of poor performing instruments.

As an ISO requirement, the Multi-Instrument Report is an extremely useful and beneficial tool for laboratories – “Laboratories with two or more analysers for examinations, should have a defined mechanism for comparison of results across analysers” – ISO 15189:2012.
