Selecting between Rayto's RAC 050 and HUMAN's HumaClot Pro coagulation analyzers requires careful consideration of performance, features, and laboratory needs. Here’s a detailed comparison:

Throughput max. tests/h (PT Only)

The maximum throughput for PT-only testing reflects the analyzer's efficiency and productivity for routine coagulation analysis. High throughput ensures rapid and consistent results, crucial for laboratories managing large volumes of tests daily.

The HumaClot Pro processes up to 86 PT tests per hour, providing a significant edge over the Rayto RAC 050, which can handle 60 PT tests per hour. The increased throughput of the HumaClot Pro makes it more suitable for high-volume testing environments.

Throughput max. tests/h (mixed mode PT/aPTT)

This measurement defines the analyzer's capacity for conducting both PT and aPTT tests in mixed mode, offering comprehensive coagulation testing. High throughput in this mode helps labs efficiently process routine and specialized coagulation tests.

In mixed mode, the HumaClot Pro can handle 58 tests per hour, while the Rayto RAC 050 manages up to 40. This difference highlights the HumaClot Pro's ability to maintain higher testing rates for comprehensive coagulation analysis.

Sample Positions

The number of sample positions indicates the analyzer's capacity to handle multiple samples simultaneously. More sample positions enable batch processing, which reduces overall turnaround times, especially during high-demand periods.

The Rayto RAC 050 provides 27 sample positions, slightly more than the HumaClot Pro's 25. This allows the RAC 050 to accommodate more samples at once, particularly beneficial for batch processing.

Reagent Positions

A higher number of reagent positions allows laboratories to store and use multiple reagents without frequent changes, leading to uninterrupted testing and enhanced flexibility.

The Rayto RAC 050 has 23 reagent positions, exceeding the HumaClot Pro's 15. This difference provides the RAC 050 with the capacity to handle a broader range of tests without frequent reagent changes.

Cuvettes on Board

Onboard cuvettes are essential for holding reagents and samples during testing. Having more cuvettes reduces the need for frequent refilling, ensuring uninterrupted testing periods and improved workflow.

The Rayto RAC 050 leads with 72 cuvettes onboard, compared to the HumaClot Pro's 32, providing longer, continuous operation for high-throughput environments.

Clotting

Clotting tests assess the blood's ability to form clots, providing critical data for diagnosing coagulation disorders. Clotting assays help in managing bleeding disorders and monitoring anticoagulant therapy.

Both the HumaClot Pro and Rayto RAC 050 deliver accurate clotting assays, offering essential insights into hemostatic function.

Chromogenic Measurement

Chromogenic assays measure specific coagulation factors or inhibitors, giving detailed information about coagulation function. This helps diagnose inherited or acquired coagulation disorders and guides treatment decisions.

Both analyzers offer chromogenic measurement capabilities, making them suitable for comprehensive coagulation analysis.

Immunologic Measurement

Immunologic tests detect antibodies and antigens related to coagulation disorders, aiding in the diagnosis and management of autoimmune or acquired coagulopathies.

Both analyzers support immunologic measurements, offering a crucial diagnostic tool for healthcare providers.

D-dimer

D-dimer testing identifies thrombotic disorders and rules out venous thromboembolism (VTE). Elevated D-dimer levels indicate coagulation activation and ongoing fibrin degradation.

Both analyzers perform D-dimer tests, providing critical data for identifying thrombotic events.

Sample Barcode Reader

Barcode readers ensure accurate sample identification and tracking, minimizing the risk of human errors associated with manual data entry.

The HumaClot Pro uses an internal/manual barcode reader, while the Rayto RAC 050 has an integrated reader. Both systems reduce sample identification errors, ensuring accurate data.

STAT Capability

STAT (short turnaround time) testing prioritizes urgent samples for immediate clinical interventions. Dedicated STAT positions accelerate processing for emergency patient care.

The HumaClot Pro provides three STAT positions, while the Rayto RAC 050 supports STAT testing as well, enabling rapid sample prioritization.

Conclusion

Choosing between the HumaClot Pro and Rayto RAC 050 depends on specific laboratory needs. The HumaClot Pro stands out with higher throughput and German-quality precision, while the Rayto RAC 050 offers a higher reagent and sample capacity. Evaluate your laboratory's testing volume, workflow, and feature priorities to make an informed decision.
