GI Pathogens

Rapid Detection of Gastrointestinal Pathogens

HealthTrackRx (HTRx) is the premier specialty diagnostic laboratory dedicated to the detection of infectious diseases.

With a decades-long track record of industry-leading technological advancement, our assays deliver accurate, actionable data with best-in-class turnaround time.

99% of samples received by our lab are reported out within 24-36 hours of receipt.

Eliminate the Guesswork in Diagnosis and Treatment

Our GI pathogen assay utilizes the latest in quantitative RT-PCR technology to rapidly and reliably analyze your patient’s sample.

We rapidly detect and differentiate 99% of the most relevant aerobic, anaerobic, and facultative bacteria, viral and fungal targets, and polymicrobial infections.

Our molecular technique provides a more definitive diagnosis than POC antigen assays and conventional culture, to precisely detect and differentiate the viral and bacterial pathogens that are the main cause of acute gastroenteritis and infectious diarrhea, including Enterohemorrhagic E. coli, Shigella and C. difficil*

Our GI Diagnostics:

  • Reduce false negatives
  • Detect polymicrobial infections
  • Are unaffected by concurrent antibiotic use
  • Include one of the most extensive antibiotic resistance gene panels
  • Reduce unnecessary drug exposure and adverse events
  • Report within 24-36 hours of sample receipt

Prescribe with Confidence

As the leader in testing sensitivity and specificity, our reports include a custom-designed accurate and detailed antibiogram.

  • Support antibiotic stewardship by reducing over-utilization of broad-spectrum anti-infectives
  • Decrease the need for empiric therapy
  • Reduce unnecessary drug exposure, adverse events, cost of repeat testing, and multiple treatment attempts

The New 99%

  • Over 99% of results are reported within 24-36 hours of sample receipt

  • Over 99% sensitivity to reduce false positives

  • Over 99% specificity to reduce false positives

  • Over 99% of the most common pathogens detected

  • 100% trackable samples and results
