Patient Case Study 3

PCR for Respiratory Infections
Before PCR Testing

Within 2 weeks, Shirley became symptomatic with a recurrent UTI. Her urinalysis was positive, and she was started on an antibiotic, cephalexin.

Shirley’s symptoms did not improve, and PCR testing was performed. It was confirmed that the recurrent UTI was a result of E. coli. Antimicrobial resistance to cephalexin was reported on the HealthTrackRx PCR Personalized Antibiogram, and Shirley was placed on twice daily nitrofurantoin.

Shirley’s symptoms resolved; however, her hospitalization could easily have been prevented.

PCR for Respiratory Infections
After PCR Testing

Four days later, Conner was admitted to the hospital with breathing difficulty and was sent to the ICU.

A full respiratory panel PCR test was ordered on the same sample as STAT.

HealthTrackRx PCR testing returned rapid results within 24 hours, and adenovirus, Streptococcus pneumoniae and Haemophilus influenzae were detected. Conner was quickly put on the correct antibiotic.

If the physician had complete PCR diagnostics when symptoms worsened, the correct antibiotic could have been given and hospitalization would have been avoided.
