Clinical applications with QuantStudio 12k flex
Why is clinical molecular microbiology testing the way forward?
Would you miss doing microbiology testing the traditional way? The good news is that physicians won’t either.
Get definitive results on pathology ID and resistance marker in minutes with QuantStudio PCR system
Given the choice, physicians often prefer getting rapid pathogen ID and resistance markers rather than waiting for colony counts and ASTs.
Molecular microbiology testing is definitely the way to future diagnostic testing.
Here’s why the QuantStudio 12K Flex is an excellent choice for clinical labs:
- Clinical compatibility: Designed to meet the rigorous demands of clinical environments, ensuring reliable and accurate results.
- Regulatory compliance: Supports compliance with regulatory requirements for LDTs, providing confidence in test validity.
- Precision and sensitivity: High sensitivity and precision, are essential for accurate clinical diagnostics.
Digital PCR machine beyond Covid testing
The QuantStudio 12K Flex Real-Time PCR System is versatile and can be utilized in a variety of clinical environments. It supports LDT molecular testing, UTI, wound panels, and numerous other applications , such as: The good news is that physicians won't either. Given the choice, physicians often prefer rapid pathogen ID and resistance markers over waiting for colony counts and AST's. Molecular microbiology testing is better for everyone involved.

Pathogen detection
Rapidly and accurately identify pathogens in patient samples.
Genetic testing
Conduct detailed genetic analyses, including mutation detection and genotyping.
Oncology research
Detect and quantify cancer biomarkers with high sensitivity.
Busy labs prefer QuantStudio 12k Flex
Reduce reruns with precision temperature control. Most real-time PCR systems use a gradient system to control temperature in their heat block. This often results in variances that can lead to inconsistent results.

The QuantStudio heat blocks are divided into 3-6 zones to control temperature precisely.
This minimizes any variables across the block. You get consistent results.
Each zone can be run at a different temperature within a single run.
So you can also set up multiple analyses with different temperature requirements to run simultaneously.
Low maintenance, low learning curve, flexible block formats
Labs prefer the QuantStudio 12K Flex for several reasons:
- Flexibility: Multiple block formats and scalable throughput.
- Precision: High sensitivity and accuracy for reliable results.
- Ease of use: Intuitive software and minimal training required.
- Integration: Compatible with TaqMan reagents and assays for consistent data.

Hear from real users:
"The interaction with instruments through voice command is highly appreciated because typically the operator has something in their hands or gloves and so forth.”
