The Cobas TaqScreen West Nile Virus Test (WNV) is a highly sensitive, automated nucleic acid test (NAT) by Roche used by blood centers to screen donor samples for West Nile virus RNA, ensuring blood and organ safety by detecting the virus early, even before antibodies appear, protecting immunocompromised patients from severe neurological complications. Running on Roche’s cobas systems (like the 6800/8800), it provides fast, reliable, and automated screening of plasma from individual or pooled donors, detecting WNV and related flaviviruses for transfusion-transmitted disease prevention

Specific pricing for the cobas TaqScreen West Nile Virus (WNV) Test is generally not public, as Roche Diagnostics provides custom quotes to healthcare facilities and blood centers based on testing volume and system service agreements.
Estimated Per-Test and Kit Pricing
While exact commercial rates vary by region, international diagnostic databases provide baseline “access” prices for Roche molecular screening:
- Per-Test Cost: For large-scale automated screening on cobas systems, estimated pricing can range from ~$7.90 to $10.90 USD per test depending on the specific volume commitment and region.
- Kit Options: Kits are typically sold in two sizes:
- 96 tests (intended for lower throughput or specific batches).
- 480 tests (standard high-throughput size for large laboratories).
Associated System Costs (2025 Estimates)
The cobas WNV test requires specific automated platforms. For facilities purchasing equipment outright rather than using a reagent rental model, typical 2024/2025 prices are:
- Cobas 5800 System: Approximately $120,000.
- Cobas 6800 System: Approximately $300,000.
- Cobas 8800 System: Approximately $600,000.
