Further Information
The ROTEM® Sigma from Werfen is a fully automated system for coagulation analysis from whole blood. Without pipetting, you obtain a clear picture of clot formation and stability within just a few minutes.
- No pipetting or sample preparation required
- Initial results in under 10 minutes
- For targeted bleeding diagnostics
- Results accessible remotely in real time
When acute bleeding occurs, every minute counts. The ROTEM® Sigma supports you in cardiac surgery, trauma care, intensive care, transplant medicine and obstetrics, helping you assess your patients' coagulation status quickly and reliably.
Depending on how your institution is organized, the device can be placed directly at the point of care or centrally in the laboratory. Results are then transmitted live to the operating room or intensive care unit, so that institutions with centralized diagnostics also benefit from a fast, seamless flow of information to the treatment team.
The ROTEM® Sigma is based on the well-established cup-and-pin method. It measures kinetic changes in clot elasticity and provides both quantitative and qualitative results, making it possible to determine whether bleeding is caused by thrombocytopenia, fibrinogen deficiency, factor deficiency or hyperfibrinolysis.
This makes the device particularly practical in everyday use:
- Closed, single-use cartridges that can be stored at room temperature
- No sample preparation or manual pipetting required
- Intuitive operation via a large touchscreen
As a result, the ROTEM® Sigma becomes a valuable tool for targeted bleeding management, with the potential to reduce unnecessary transfusions, complications and costs within your institution.
Axonlab supports you not only with the purchase, but also afterwards: with competent application support that assists you during implementation and throughout day-to-day operation, as well as our technical team, available to you across Switzerland.
Expert opinion
Here's what our experts say about the product
What convinces me about the ROTEM sigma is the minimal number of user steps. In acute care there is no time for manual sample preparation, it is enough to insert the closed tube, and the analysis starts automatically. This lowers both the time-to-result and the risk of error, decisive under time pressure. This makes the ROTEM sigma a key building block in Patient Blood Management, since fast, reliable values help avoid unnecessary transfusions.Expert since 2016
