The measurement of measurable residual disease (MRD) populations is often performed following treatment for leukaemic disorders. The levels are used as a predictive factor for relapse or an indicator for patients entering remission. As such the measurement of MRD can have a direct effect on the treatment regimen of a patient.
This programme issues stabilised whole blood into which has been spiked some stabilised plasma cell myeloma material. Laboratories are required to determine the level of measurable residual disease by flow cytometry, please note this programme is not suitable for the measurement of MRD by molecular methods.
The programme issues a presentation sample together with 2 follow up samples. Please note that the presentation sample will not contain the expected level of disease seen in a typical clinical scenario. The 2 follow up samples are manufactured from the same plasma cell myeloma case and are designed to represent different stages post treatment to assess the ability of a centre to detect B plasma cell myeloma cells at minimal residual disease levels within a background of stabilised normal whole blood. Laboratories are requested to report the percentage of residual neoplastic plasma cells in the 2 follow up samples as a percentage of the plasma cell population.
Three samples are issued per trial and this programme issues samples a minimum of 2 times per annum and a maximum of 3.
***NEW IN 2022-2023*** The Minimal Residual Disease Programmes have been renamed in line with current naming conventions and will now be called Measurable Residual Disease Programmes. All other aspects of the programme operation will remain unchanged.
No activities in relation to this EQA programme are subcontracted.
