New rapid test could help ICU doctors pick the right antibiotic hours faster
NCT ID NCT07202377
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new rapid diagnostic system that can tell doctors which antibiotic will work against a blood infection in 4-6 hours, instead of the usual 18-24 hours. Researchers want to see if this faster information helps ICU doctors change to a better antibiotic sooner. The trial will include 200 adult ICU patients with Gram-negative bloodstream infections.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SPECIFIC REVEAL® Rapid AST system (diagnostic test)
- What this could lead to
- If successful, this could show that faster lab results help doctors pick the right antibiotic sooner, potentially improving patient outcomes in the ICU.
- What could go wrong
- This is an early-stage study with only 200 patients, so results may not apply to all hospitals. The test itself is new and may not always be accurate or available.

Inclusion Criteria: * Adult patients aged over 18 years * Patients with a positive blood culture for Gram-negative bacilli (Enterobacterales, Pseudomonas aeruginosa, Acinetobacter baumannii) with results reported on weekdays before 11:00 ante meridiem (AM) * Patients clinically suspected of infection * Treated with empirical antibiotic therapy including a β-lactam, among the standard list of antibiotics to be tested recommended by CASFM-EUCAST (European Committee on Antimicrobial Susceptibility Testing) for Enterobacterales/Pseudomonas and included in the Reveal Rapid AST System panel * Hospitalized in intensive care unit (ICU) for at least the next 24 hours * Written informed consent obtained from the patient or a relative for study participation (emergency consent) * Affiliated with the French social security system Exclusion Criteria: * Patients receiving withdrawal or limitation of care * Patients with an expected survival prognosis of less than 72 hours * Patients with bloodstream infections caused by Gram-negative bacilli other than Acinetobacter baumannii, Citrobacter freundii, Citrobacter koseri, Enterobacter cloacae, Escherichia coli, Klebsiella aerogenes, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, or Pseudomonas aeruginosa * Patients treated with antibiotic therapy not including a β-lactam * Polymicrobial bloodstream infections * Pregnant or breastfeeding women * Patients under legal protection (guardianship or conservatorship) * Participation in another interventional research study
