24-hour detection of Pseudomonas aeruginosa in pool, spa or hospital water

Detects or quantifies Pseudomonas aeruginosa in pools, spas, hospital water systems and bottled water in a 100 ml format.

Use the Pseudalert® Test to quickly detect P. aeruginosa. Pseudalert helps you protect sensitive populations and prevent infections such as hot-tub rash (folliculitis) and swimmer’s ear.

Detects P. aeruginosa in 24 hours.
Results with no additional confirmation steps.
High sensitivity and specificity ensure accuracy.
No filtration or media preparation required.

Pseudalert: Be confident in your outcomes


  • Blue fluorescence of wells or vessel indicates a positive result.
  • Same familiar platform as the Colilert® test:
  • Ready-to-use reagents, no media preparation.
  • Convenient unit-dosed packaging.
  • No toxic compounds.
  • Use with Quanti-Tray® or Quanti-Tray®/2000 for most probable number (MPN) enumeration.


  • Definitive results in 24 hours.
  • Less than 1 minute of hands-on time for streamlined testing work flow.

  • Specifically detects Pseudomonas aeruginosa, reducing the risk of false positives from nontarget organisms.
  • Results are definitive without additional confirmation steps.
  • Simple blue fluorescent change minimises subjective result interpretation

Technical Specs
Ingredients / Manufacturing Materials How Pseudalert® works
The Pseudalert test detects the presence of Pseudomonas aeruginosa in water samples.
The test is based on a bacterial enzyme detection technology that signals the presence of P. aeruginosa through the hydrolysis of a substrate in the Pseudalert reagent. P. aeruginosa cells rapidly grow and reproduce using the rich supply of amino acids, vitamins and other nutrients present in the Pseudalert reagent. Actively growing strains of P. aeruginosa have an enzyme that cleaves the substrate in the reagent to produce blue fluorescence under ultraviolet light.
Pseudalert detects P. aeruginosa at 1 cfu per100 ml sample within 24 hours.
