Hair, Nail & Paronychia Pathogens

Rapid Detection of Hair, Nail & Paronychia 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 hair, nail, & paronychia 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, as well as polymicrobial infections, including fungi and more than 25 of the most common dermatophytes, saprophytes, and yeast. .

Our molecular technique provides a more definitive diagnosis than POC antigen assays*

Our Hair, Nail, & Paronychia Diagnostics:

  • Reduce false negatives
  • Detect polymicrobial infections
  • Are unaffected by concurrent antibiotic use
  • Include one of the most extensive antibiotic resistance gene menus
  • 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 negatives

  • Over 99% specificity to reduce false positives

  • Over 99% of the most common pathogens detected

  • 100% trackable samples and results
