Introduction to the Siemens Advia Hematology Series
The Siemens Advia 2120 has been a trusted hematology analyzer in clinical laboratories for years. Known for its high throughput and reliable results, it automates complete blood count (CBC) testing with advanced optical and cytochemical technology. However, with the release of the Siemens Advia 2120i, many labs are now evaluating the differences between the two systems to determine if an upgrade is worthwhile.
Both analyzers serve similar purposes, but subtle differences in features, workflow integration, and user interface may influence lab efficiency. This article provides a comprehensive comparison between the two models to help labs make informed decisions.
Core Technology: What Stays the Same?
Both the Siemens Advia 2120 and the 2120i use the same core technology for analyzing blood samples. This includes:
Peroxidase staining for WBC differentiation
Laser-based flow cytometry
RBC and platelet analysis using multi-angle light scatter
The results are dependable in both systems, delivering precise hemoglobin levels, hematocrit, MCHC, and other standard parameters used in diagnosing various hematological conditions.
Key Upgrades in the Siemens Advia 2120i
The Siemens Advia 2120i is essentially an enhanced version of the 2120, focusing on operational efficiency and serviceability. Here are the main improvements:
Improved User Interface:
The 2120i comes with a more intuitive software layout and touchscreen controls, which simplify operation and reduce training time for lab technicians.Enhanced Maintenance Design:
The newer model includes easier access to system components. Service technicians can perform preventive maintenance more quickly, reducing downtime.Faster Start-Up and Calibration:
Labs using the 2120i experience quicker daily startup routines and more efficient calibration checks, which is especially helpful for high-volume labs.Data Connectivity and LIS Integration:
The Advia 2120i offers better connectivity options for laboratory information systems (LIS), improving data management and reporting speed.
Workflow and Throughput Comparison
Both analyzers handle approximately 120 samples per hour, but the 2120i achieves slightly faster results in some workflow scenarios due to its streamlined processes. Additionally, the 2120i is more compatible with automation systems such as the Siemens Atellica CH 930, making it a better choice for labs aiming to fully automate their hematology department.
Maintenance and Support
The original Siemens Advia 2120 remains serviceable and continues to receive support from Siemens Healthineers. However, the 2120i includes more proactive maintenance alerts and built-in troubleshooting guides. These updates help labs avoid unexpected errors and reduce technician workload.
Training and Transition
For labs transitioning from the 2120 to the 2120i, the learning curve is minimal. The instruments share similar layouts and testing procedures. Siemens provides upgrade guides, user manuals, and on-site training to support smooth integration.
Cost Considerations
While the Siemens Advia 2120i has a higher upfront cost than the original 2120, the long-term savings in maintenance, reduced downtime, and workflow improvements may justify the investment. Labs should consider their sample volume, staffing, and automation needs before making a purchase decision.
Final Thoughts
In summary, the Siemens Advia 2120 continues to be a solid and reliable hematology analyzer for many labs. However, the Advia 2120i introduces meaningful improvements in usability, integration, and maintenance that can elevate lab efficiency. If your facility is planning to upgrade its hematology equipment or streamline automation with instruments like the Siemens Atellica CH 930, then the Advia 2120i might be the better fit. For labs with stable workflow and tight budgets, the classic 2120 still delivers excellent performance.
Ultimately, both models support accurate and automated CBC testing, helping healthcare professionals deliver timely and reliable patient diagnostics.
