Chemistry and Immunoassay Integrated Workstation

What is the Chemistry and Immunoassay Integrated Workstation?

This workstation integrates a chemistry analyzer with an immunoassay module so that biochemical and immunochemical tests run from the same tube under one worklist. It suits laboratories that consolidate chemistry and immunoassay into a single operating team and reporting stream.

Overview

The configuration places a chemiluminescence or enzyme immunoassay module alongside the photometric chemistry channels, connected by a shared loader or a short transfer mechanism. Sample volumes are aspirated once and distributed to both sections, which reduces tube handling and the risk of mismatched results between two separate analyzers. Chemistry results and immunoassay results appear in one report, and the middleware can apply combined rules, for example restricting a cardiac marker report until the chemistry panel has been accepted. Reagent storage differs between the two technologies, so refrigerated compartments and instrument maintenance must follow each module requirement. Immunoassay reagents require lot-specific calibration, and the laboratory must plan calibration, control and interface validation for both sections before go-live.

How does it work?

A chemistry workstation is defined by integration rather than by a single measurement principle. Photometric modules using interference filters or gratings measure colorimetric and enzymatic reactions, ion-selective electrode modules measure sodium, potassium, chloride and calcium, and immunoturbidimetric modules measure specific proteins from the light scattered by antigen-antibody complexes. Around these analytical modules the workstation adds pre-analytical handling such as rack loading, tube inspection with cameras for volume and hemolysis assessment, sorting to the correct module, and post-analytical storage of the tubes in a refrigerated archive. Middleware coordinates sample routing, applies reflex and rerun rules, tracks reagent inventory across modules and manages quality control in one record set. Interfaces to the laboratory information system use HL7 or ASTM, so the workstation appears to the user as one analytical unit with a single worklist.

What are the key features?

• Chemistry and immunoassay sections connected by a shared loader
• Single aspiration distributed to both detection sections
• Combined reporting of biochemical and immunochemical results
• Middleware rules linking the two sections, such as cardiac panels
• Separate refrigerated reagent storage for each technology
• One LIS connection for the integrated platform

What are the technical specifications?

A typical chemistry and immunoassay integrated workstation configuration offers chemistry throughput of 600–1000 tests/h photometric, immunoassay throughput of 100–240 tests/h, immunoassay principle of Chemiluminescence or enzyme immunoassay, sample volume of 1.5–35 µL chemistry; 20–100 µL immunoassay, reagent storage of Separate refrigerated compartments at 4–10 °C and calibration of Chemistry multi-point; immunoassay lot-specific curves. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Chemistry and Immunoassay Integrated Workstation is used in consolidated chemistry and immunoassay reporting, cardiac marker and routine panel workup, endocrine testing alongside biochemistry and laboratories merging two operating teams. Across the wider Chemistry Workstations class, laboratories also deploy it for high-volume consolidated biochemistry testing, core laboratory workflows with automated sorting and multi-module specific protein and electrolyte testing.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, CLSI AUTO10, CLSI EP05, CLSI EP06, CLSI C24, IEC 61010-1 and IEC 61010-2-101. Certification candidates for this model are CE, ISO 13485 manufacturing and NMPA class II registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

A workstation installation is a project rather than a single delivery: plan power distribution, network points, water supply and drainage, air conditioning and floor loading for every module in advance. Verify each analyzer module individually, then validate the integrated workflow for sorting accuracy, sample inspection results, middleware rules and archive retrieval. Build the reagent and consumable logistics for all modules into one inventory system, because running out of one reagent stops the affected channel without stopping the platform, which can mask the problem. Define and rehearse a partial-downtime procedure, clean sample paths and cameras daily, and monitor that middleware rules continue to match the clinical requirements after any software update.

How do I select the right Chemistry and Immunoassay Integrated Workstation?

Choose this configuration when chemistry and immunoassay currently run on separate instruments under separate teams and a large share of samples need both. In the RFQ confirm that each section can operate independently, whether results can be released separately, and how lot-specific immunoassay calibration and controls are managed within the shared software.

How does it compare with other Chemistry Workstations variants?

Decide a workstation configuration only after mapping your test menu by module and your daily tube count, because the integrated platform pays back through reduced handling and consolidated reporting rather than raw speed. Compare candidate systems by which modules can be combined, whether sorting is barcode-driven, whether tube inspection for hemolysis and icterus is included, and how much refrigerated archive capacity is offered. Check that middleware can implement your review rules and that it communicates through a single LIS connection. Confirm the space, water, drainage and power requirements of each module plus the archive, and the validation workload at installation. Ask whether the configuration can be expanded with another module later, and whether the archive can be upgraded independently of the analyzers.
