Internal quality control (QC) is the backbone of quality system in laboratory medicine, which serves to validate patients test results. However, it monitors the system intermittently, not continuously. Classical QC monitoring system depends on periods such as weeks, days, or predetermined time intervals and therefore detects some but not all analytical defects. In this situation, we have not much information about what is going on between these periods. To overcome this problem, we need a real-time monitoring system to detect the possible errors while the instruments are running.

Autoverification programs evaluate and release test results as soon as they receive data from the instruments. Therefore, when we detect errors using classical QC monitoring system, the test results of a large number of patients might have been reported to clinicians and/or patients already. This is a major risk for patients’ safety and when we detect errors, it wouldn’t be easy to re-analyse all reported patients’ samples. 

The devil is in the detail. We should monitor the system continuously using a suitable algorithm based on patients’ data. The aim of this webinar is to raise awareness for the necessity to monitor analytical instruments continuously while reporting test results.

The importance of standardisation is only just being realised and addressed in autoantibody measurements.  Immunoglobulins have a high degree of molecular heterogeneity, there are subclasses of IgG and IgA, and the affinity and avidity of antigen-antibody binding can vary both between and within individuals.  An immune stimulus may generate a monoclonal, oligoclonal or polyclonal response and this pattern of response will vary between individuals and even within an individual over the disease course.  There are multiple methods available for autoantibody detection which will vary in their abilities to detect different types of immunoglobulins.  Finally, the antigen to which we are trying to measure antibodies is usually a protein with its own molecular heterogeneity which may also be influenced by the source of the antigens and the preparation process.  Considering these complexities, it is unsurprising that there is marked variation in autoantibody concentrations measured with different methods.  However, the increasing reliance on automated quantitative autoantibody results has made standardisation or harmonisation of these tests vital.  The IFCC through a working group and more recently a committee have been integral to investigating and producing certified materials for IgG anti myeloperoxidase (ERM-DA476/IFCC) and IgG anti proteinase 3 (ERM-DA483/IFCC) with values assigned in mg/L, traceable to ERM Da 470k/IFCC (the certified reference materials for IgG).  Evaluation of patient samples showed that use of these materials will give a significant reduction in the spread of the numerical results over different methods.  However, there was only 30% concordance between positivity and negativity of results when interpreted with respect to each methods reference ranges.  The introduction of certified reference material (CRM) will be the essential first step in standardisation of autoantibody testing and although it does not solve every issue, it should give us a point of reference to identify the other components of the methods that need to be harmonised before we can have comparability in autoantibody results.
