Which point-of-care immunoassay devices are known for high sensitivity and fast turnaround?

Point-of-care immunoassay devices known for high sensitivity and fast turnaround usually fall into a few major platforms:

Common high-performing POCT immunoassay device types

• Lateral flow immunoassays (LFIA / rapid tests)

  • Very fast, often 5–20 minutes
  • Widely used for pregnancy, infectious disease, and some antigen tests
  • Sensitivity can vary, though newer fluorescence-enhanced versions improve performance

• Fluorescent immunoassay analyzers

  • Examples include Getein, FiaFlow, Acutherm, Ichroma, and similar handheld/bench-top systems
  • Typically faster than central lab testing, often ~10–20 minutes
  • Generally better sensitivity than basic visual lateral-flow tests

• Chemiluminescent immunoassay (CLIA) point-of-care systems

  • Often provide high analytical sensitivity
  • Turnaround can still be relatively quick, usually ~10–30 minutes
  • Used for cardiac markers, hormones, inflammation markers, and some infectious disease tests

• Microfluidic immunoassay platforms

  • Small sample volumes, rapid reactions, and good sensitivity
  • Often integrated into cartridge-based systems
  • Turnaround can be minutes to under 30 minutes

• Digital immunoassay systems

  • Among the most sensitive POCT options
  • Designed to detect very low concentrations of biomarkers
  • Usually still deliver results in ~10–20 minutes
  • Examples include ultra-sensitive cardiac or infectious disease assays

Well-known device families/platforms

Some widely recognized systems in this space include:

• QuidelOrtho Sofia / Sofia 2
• Abbott i-STAT (more of a cartridge-based POCT platform; some assays use immunoassay methods)
• Roche cobas h 232
• Boditech iChroma
• Abbott Afinion
• Siemens CLINITEST / POCT immunoassay tools
• LumiraDx (notable for high sensitivity and rapid results; platform availability varies by region)

In general

If you want the best combination of sensitivity + speed, look for:

• Fluorescence-based immunoassays
• Chemiluminescent POCT
• Digital immunoassay platforms
