Operating at the core of clinical laboratory operations, the Roche Cobas 8000 (c702 / c502 / e801) from Roche Diagnostics delivers specialized Biochemistry & Immunoassay diagnostics for Flagship high-volume modular diagnostic system processing thousands of samples daily in major central labs.. Direct integration with AILS Cloud LIMS establishes an automated bi-directional link that eliminates lost results, enforces sample volume compliance of 1.0 - 35 µL, and maximizes walkaway processing up to Up to 9,800 tests/hour in maximum configuration using authentic ASTM E1381 / E1394 over TCP/IP LAN message framing.
As specimen tubes advance on the Roche Cobas 8000 (c702 / c502 / e801), the integrated barcode scanner identifies the primary tube barcode and dispatches an instant query to AILS Gateway. The gateway dynamically returns patient demographics, assigned test orders (Full consolidated Roche menu across chemistry, immunochemistry, and serolog...), and auto-dilution factors, completing Advanced bi-directional host query with STAT priority rack lane management in sub-300ms.
All observations received from the Roche Cobas 8000 (c702 / c502 / e801) undergo automated evaluation against age- and sex-stratified reference intervals, Westgard multirules (1-3s, 2-2s, R-4s, 10x), and Levey-Jennings charts. Control failures automatically halt patient result release on affected channels.
