If you’re running a biotech startup, scaling a diagnostics pipeline, or outfitting a clinical lab, you’ve probably come across one key question: how much does an immunoassay analyzer actually cost?
The answer isn’t simple—but it’s essential. Immunoassay analyzers come in a wide range of formats and price points, from compact benchtop ELISA readers to fully automated chemiluminescence immunoassay systems (CLIA) designed for high-throughput clinical diagnostics.
Need a refresher on how immunoassays work or what types are out there? Read our immunoassay overview here.
And while sticker price matters, so do throughput requirements, consumables, reagents, maintenance, and the broader role the analyzer plays in your workflow.
In this post, we’ll break down typical price ranges, what factors drive cost, and how to think about value beyond the initial purchase. Whether you’re evaluating refurbished options, budgeting for a new facility, or weighing leasing vs. buying, this guide will help you make a smarter, more strategic decision.
Typical Price Ranges by Analyzer Type
Immunoassay analyzer costs vary widely based on format, automation, and throughput. Here’s a quick breakdown:
- Benchtop ELISA and FIA systems: Entry-level systems typically run $5,000–$25,000 USD. These include ELISA readers and fluorescence immunoassay analyzers like the bioMérieux VIDAS, Radiometer AQT90, or Thermo Fisher Scientific benchtop units. They’re ideal for small labs or point-of-care testing but are lower throughput and often semi-automated.
- Mid-range automated systems: Priced between $30,000–$100,000 USD, these platforms support higher volumes, offer faster turnaround, and run a broader test menu. Examples include the Tosoh AIA-900, Roche cobas e 411, and Beckman Coulter Access 2. Refurbished models in this tier can offer good value with a valid warranty.
- High-throughput analyzers: Fully automated systems for large clinical labs can cost $100,000–$250,000+ USD. These include the Siemens ADVIA Centaur, UniCel DxI series, and Abbott ARCHITECT i2000SR. Designed for continuous operation, they support large volumes and full LIS integration.

What Drives the Cost of an Immunoassay Analyzer?
The sticker price is just the starting point. What you actually pay—upfront and over time—depends on a mix of technical, operational, and financial factors:
Automation level
Manual and semi-automated analyzers cost less upfront but require more staff time. Fully automated systems reduce hands-on time, improve reproducibility, and support continuous operation—but cost significantly more.
Throughput requirements
Higher sample volumes demand systems with faster processing speeds, larger onboard reagent storage, and robust uptime guarantees. Expect to pay more for instruments that can handle batch testing or high-throughput workflows.
Assay menu & technology
CLIA (chemiluminescence), FIA (fluorescence), and RIA (radioimmunoassay) technologies vary in sensitivity, complexity, and cost. Instruments that support a wide range of analytes—proteins, antigens, antibodies, biomarkers—often come with higher system and reagent costs.
Reagents & consumables
Some platforms lock you into proprietary reagents or single-source consumables. Others offer more flexibility. Always factor in reagent pricing, shelf life, and volume discounts—especially for diagnostics labs running frequent assays.
Warranty & service contracts
A full-service warranty can add 10–20% to your initial cost but may be essential for uptime. For refurbished analyzers, make sure service is available locally, and ask whether parts are still supported by the manufacturer.
Integration & data systems
If you need LIS or EMR integration—or plan to pair your immunoassay analyzer with a chemistry analyzer—be prepared for added software, interface, and validation costs.
Leasing vs. Buying: When to Consider Alternatives
If you’re building or scaling a diagnostics pipeline, buying new equipment outright isn’t always the smartest move—especially when budgets are tight or timelines are uncertain. Immunoassay systems are capital-intensive, and total cost of ownership extends far beyond the purchase price.
Leasing can offer a flexible alternative, particularly for startups, CLIA labs in growth mode, or contract labs juggling multiple client demands. It spreads costs over time, keeps cash free for reagents, staffing, or assay development, and may include service, upgrades, or consumables depending on the agreement.
When leasing makes sense:
- You’re launching a new lab and want to preserve runway
- You expect testing volumes to grow but aren’t sure by how much
- You’re evaluating multiple analyzers and don’t want to commit yet
- You need equipment fast, without waiting on capital approvals
- You want a bundled agreement that includes service and warranty
That said, leasing isn’t for everyone. If your lab has stable volumes, reliable funding, and in-house service capabilities, purchasing—especially refurbished—may yield better long-term savings.
Choosing The Right Analyzer For Your Workflow
Buying (or leasing) the right immunoassay analyzer isn’t just about specs—it’s about fit. Your workflow, sample types, team size, and testing goals should guide the decision.
Start with your use case
Are you running R&D assays, CLIA-certified diagnostics, or screening for infectious disease? Different workflows favor different technologies—ELISA may work for basic antigen detection, while high-throughput CLIA systems shine in clinical diagnostics.
Match throughput to reality
Labs often overbuy in anticipation of scale. If you're processing fewer than 50 samples per day, a benchtop or mid-range analyzer may be more cost-effective than a high-throughput platform that sits idle.
Consider space, staffing, & integration
Do you have space for a large analyzer—or just a tight benchtop footprint? Is your team trained to maintain automated systems, or would simpler equipment reduce downtime? Will the analyzer need to sync with existing LIS or EMR systems?
Don't ignore consumables
Ongoing reagent costs can rival or exceed the analyzer’s price over time. Platforms like Abbott, Roche, or Beckman Coulter Access often require proprietary reagents. Ask for detailed cost-per-assay estimates and look for volume pricing where possible.
Refurbished can be smart—if supported
Validated, serviced systems from vendors like Siemens, bioMérieux, or Tosoh can be a cost-effective way to ramp up capabilities. Just ensure warranty, parts, and service are still available.
Final Considerations: What to Ask Before You Buy
Before committing to any immunoassay system—new, refurbished, or leased—slow down and pressure-test the fit. The wrong decision can create workflow bottlenecks, unexpected costs, or reliability issues that ripple across your lab.
Ask these questions first:
- What’s the total cost of ownership?
Include the analyzer, reagents, consumables, service contracts, and any LIS integration fees. Get a realistic picture over 3–5 years. - How easily can we scale?
Can the system grow with you—or will you need to upgrade again soon? Modular or multi-platform setups (like the Vitros or Advia Centaur) may offer more flexibility. - What’s the support model?
Does the vendor offer on-site service? Is remote troubleshooting available? For lean teams, fast support can make or break uptime. - Is this platform widely adopted?
Systems with strong market presence—like those from Roche, Siemens, or Thermo Fisher Scientific—tend to have more reliable parts, better documentation, and longer support lifespans. - What validation or compliance steps are required?
Especially for CLIA-certified labs or healthcare-adjacent workflows, be sure the analyzer is FDA-cleared or CE-marked and that SOPs and QC procedures are documented.
Every lab has different constraints, but asking the right questions early helps avoid regret later.
Final Thoughts
An immunoassay analyzer isn’t just another piece of clinical lab equipment—it’s a core part of your lab’s diagnostic or discovery engine. Whether you’re focused on antibodies, proteins, or clinical biomarkers, the right system can unlock speed, accuracy, and scalability. But it’s not just about finding the “best” analyzer—it’s about finding the right fit for your budget, throughput, and operational reality.
If you’re weighing options—buying new, exploring refurbished systems, or considering a lease—take the time to model the tradeoffs. What makes sense today might shift as your assays evolve, volumes grow, or funding opens up.
