RHP manages the database Minerva. This database assesses the analysis results of samples.

A number of agreements has been made for the processing of these results:

  • Analyses are sent in with RHP code and location code for the traceability. Without these data, no processing can take place.
  • The lab sends the data to Minerva within 48 hours after closing the test.
  • Minerva processes the results within 24 hours.

Reassessment or reanalysis of results 

Members regularly ask to correct incorrect results in Minerva, the database which assesses the analysis results of samples. The term ‘reanalysis’ is often used, while it’s actually about an other kind of reassessment. What exactly about these reassessments? 5 tips from Frank Woets, technical adviser at RHP:

TIP 1: Examine well, what kind of reassessment it’s about

A reassessment is always a procedure which has to correct probably incorrect results. There are four levels of reassessment:

  • Remeasurement by the lab (RML), remeasurement reanalysis) of the original sample in the laboratory
  • Resampling and measurement (RSM), resampling of a new sample of the same consignment.
  • Resampling on counter sample (RSC), resampling on the counter sample of the same consignment
  • Recipe verification and measurement (RVM), measurement of a new sample of a new consignment that has been produced according to the recipe of the original consignment (recipe verification)

The names of these reassessments indicate how much resemblance the analysed sample has with the formerly analysed sample. In the list above, that resemblance of samples decreases top-down. The name also indicates the kind of mistake that probably has arisen.

Tip 2: Use the right codes 

Our aim is to improve the transparency and traceability of reassessments. By running this process in a more structured manner and partly automated with the use of database database Minerva 2.0. The correct and uniform coding of samples by members and laboratories is important then. The results of a second measurement in a sample indication can be recognized on the following codes (ever without the hyphen):

  • RML-space-test number
  • RSM-space-assessment number
  • RSC-space-assessment number
  • RVM-space-assessment number

The assessment number in the last three is ever the same as that of the assessment of the first result by Minerva.

Tip 3: Results having cancelled? Request the certifying body

Once results have been stated in Minerva – when they appear to be incorrect later on – then RHP cannot have them cancelled just like that. Permission from the certifying body (ECAS or KIWA) is necessary. To have an assessment cancelled, the member can apply for a request at his certifying body. Provided with an adequate foundation. The certifying body determines if the first assessment may be cancelled and informs RHP. A sample can and may be rejected only once by the way.

Tip 4: Enter all specifications on the sample form

If specifications of a sample are lacking, then the results cannot be approved by Minerva. So a rejection follows. As soon as the certifying body gives permission to reassess the results with the specifications, Minerva can do this. So it is better and quicker to take care of the right specifications on the sample form right away.

Tip 5: So take care of reanalyses as little as possible

Prevention is better than cure. So take care of good sampling, labelling and a correctly completed sample form to minimise the chance on mistakes. In this way we jointly keep the number of re-analyses as small as possible.
