ECAT Webinar


 

During the last ECAT symposium September 2022 prof. dr. Panagiotis Tsiamyrtzis gave an excellent presentation on the interpretation of Z-scores used in the ECAT survey reports. This included also an explanation of the bivariate Z-score plots recently introduced in the ECAT survey reports. Unfortunately, this presentation was not recorded. Therefore we decided to organise a webinar on this topic. We are very grateful that prof. dr. Tsiamyrtzis is willing to contribute to this webinar. This webinar can be followed free-of-charge, however registration is mandatory. The registration opens soon at the ECAT website.

Participant area

The participant area gives you access to, for instance, the survey result submission forms, the survey reports and documents. Within the Participant Area you can choose the required action as result submission or downloading a required report. Recently we have updated on our website the access to the participant area. Select in the menu on our website (www.ecat.nl) the option Participant Area. To login to the Participant Area you select the blue button “Click here”.



Now you have to login and you enter into the Participant Area.
Survey manual

The Survey Manual 2023 is now available at our website. To get access to the Survey Manual, please go to the Participant Area. In the top menu you see the option View Documents. Select this option.



At the bottom of the page you will see a section with useful documents. Here you can find your Survey Manual. If you want you can download the document and store it on your own pc or make a print of the document.

Changes in several modules

With the start of the external quality assessment programme 2023 we have introduced a number of changes in several modules. Below we summarise these changes. More details can be found in the Survey Manual 2023.

Haemophilia Programme
The modules related to laboratory testing for haemohilia A and B are now included in a separate programme: Haemophilia Programme. For this programme a separate result submission form and survey report is provided. These modules are not included anymore in the Main report.

Lupus Anticoagulant
For Lupus Anticoagulant it is now possible to report results for a mixing test performed with the confirmation reagent separate from the mixing test with the screening reagent.

Thromboelastography
For the Thromboelastography Programme the number of parameters for which results can be submitted is extended. Results for the following parameters can be submitted:


HIT
It is now possible to submit results for three test systems.

New Publication  


We are proud to announce a recent publication in Clinical Chemistry and Laboratory Medicine (CCLM). Together with our colleagues from NOKLUS we have performed a systematic review of published data on the biological variation for coagulation and fibrinolytic measurands. This is publication can be reached with the following link: https://www.degryuter.com/document/doi/10.1515/cclm-2022-1207/html
Soon, the data from the meta-analysis will be added to the EFLM Biological Variation Database (https://biologicalvariation.eu

Recent publications

Below we list some interesting recent publications in the field of thrombosis and haemostasis, and laboratory diagnostics. Because of the enormous number of publications we have limited our reporting to just a small list of interesting publications. It is not our intention to provide you with a complete overview. We hope this list supports you in your awareness of interesting publications.
