Are there any isothermal amplification systems that focus on rapid infectious disease workflows?

Yes. A number of isothermal amplification systems are designed specifically for rapid infectious disease workflows, especially where fast turnaround and simpler instrumentation matter more than full PCR thermocycling.

Common examples include:

• LAMP (Loop-mediated Isothermal Amplification)
  Widely used for rapid detection of pathogens. Often delivers results in about 15–60 minutes and can be paired with fluorescence, turbidity, or lateral-flow readouts.

• RT-LAMP
  A reverse-transcription version of LAMP for RNA viruses such as SARS-CoV-2, influenza, RSV, etc. Very common in point-of-care and near-patient workflows.

• RPA (Recombinase Polymerase Amplification)
  Another fast isothermal method, often operating at ~37–42°C with results in under 30 minutes. Attractive for portable/field testing.

• HDA (Helicase-Dependent Amplification)
  Less common than LAMP/RPA, but also used for pathogen detection without thermal cycling.

• NEAR (Nicking Enzyme Amplification Reaction) and related proprietary assays
  Used in some rapid molecular diagnostic platforms for very short time-to-result.

Systems/platforms used in infectious disease workflows

Examples of platforms that use these methods include:

• Abbott ID NOW — uses isothermal amplification for rapid molecular testing.
• Cue Health — isothermal amplification-based rapid testing platform.
• bioMérieux BIOFIRE?
  More commonly PCR-based for syndromic panels, so not isothermal, but often mentioned in rapid infectious disease workflows.
• Quidel-Ortho Sofia/QuickVue molecular offerings — some rapid molecular tests are isothermal-based depending on assay.
• Thermo Fisher / TwistDx / HiberGene and others — provide LAMP/RPA-style assays or components.

Why they’re used in rapid workflows

• Minimal instrumentation
• Faster time-to-result than standard PCR
• Potential for point-of-care use
• Easier sample-to-answer integration

Typical infectious disease targets

• Respiratory viruses: SARS-CoV-2, influenza, RSV
• STIs: Chlamydia, Gonorrhea
• TB
• GI pathogens
• Bloodstream and respiratory bacterial pathogens
• Emerging pathogens in outbreak settings
