The QuantStudio™ Dx Real-Time PCR Instrument represents 20 years of qPCR innovation and our commitment to enhancing molecular diagnostics solutions.

The QuantStudio™ Dx instrument provides your clinical laboratory with performance you can trust, security you demand, and flexibility you need in your workflow to meet the needs of your lab today and tomorrow.


QuantStudio™ Dx instrument


Results you can trust
The QuantStudio™ Dx instrument’s proven performance, security, and reliability—combined with the outstanding sensitivity and specificity of the Quidel® Assays including Molecular Direct C. difficile Influenza A + B and Respiratory syncytial virus (RSV) and human metapneumovirus hMPV assays—help ensure that the right answer is delivered the first time, and every time.

Flexibility you want
In Test Development Mode, the QuantStudio™ Dx instrument enables the creation of new assays in 96-or 384-well plates, and qPCR Microfluidic Card formats provide easily interchangeable thermal cycling blocks to accommodate your lab’s throughput assay development. The 96-well fast block can be used in IVD mode.

Efficient workflows
A simplified instrument and assay workflow as well as intuitive software makes the entire test—from processing to reporting—efficient and cost-effective. Plus, it frees up highly trained operators to perform more complex tasks. The Quidel® Molecular Direct C. difficile Assay is currently the only approved assay for use in the United States on the QuantStudio™ Dx Instrument with additional assays in development.

Diagnostics platform that grows with you
Through our partnership with Quidel® Corporation, we are in the process of developing a growing list of assays to accommodate your testing needs. Starting with the Molecular Direct C. difficile, Influenza A + B and Respiratory syncytial virus (RSV) and human metapneumovirus hMPV assays in the US, the expanded assay menu in the future may include tests for HSV 1+ 2/VZV and other infectious diseases, and also for oncology and inherited diseases.

QuantStudio DX

What IVD assays are available?

The Quidel® Molecular Direct C. difficile, Influenza A + B and Respiratory syncytial virus (RSV) and human metapneumovirus hMPV assays are the first of our growing assay menu validated for use with the QuantStudio™ Dx Real-Time PCR System. A strong pipeline of assays are currently in development including, Direct HSV 1+ 2/VZV. Our future offerings will also include tests for oncology and inherited diseases.

What formats does the instrument support?

For assay development: qPCR Microfluidic Card, 96-well Fast and standard, and 384-well formats in the US.†

For IVD: 96-well Fast format in US; qPCR Microfluidic Card, 96-well Fast and standard, and 384-well formats in Europe.

What is a qPCR Microfluidic Card?

It is a Life Technologies proprietary 384-well qPCR Microfluidic Card designed to perform 8 x 48 simultaneous reactions without the need for liquid-handling robots.

What applications does the instrument support?

The QuantStudio™ Dx instrument has you covered across several applications, whether you perform pathogen detection, gene expression analysis, SNP genotyping, copy number analysis, mutation detection with castPCR™ technology, microRNA and other non-coding RNA analysis, or high-resolution melt (HRM) analysis.§

What size is the instrument?

The instrument dimensions are 53.0 cm (20.9 in) x 70.0 cm (27.6 in) x 75.0 cm (29.5 in). It weighs 70 kg (154.3 lb).

How long does it take to run a typical PCR assay?

Cycle times depend on the test being performed and the thermodynamic requirements. Typically it takes less than 60 minutes from sample acquisition to reporting.

What is the hands-on time?

Approximately 15 minutes. It takes less than 10 minutes to setup the plate, 1 minute to cycle and image, and less than 5 minutes to analyze the data and generate the report.
