"pointless antibiotic use might contribute to the rise in antibiotic-resistant infections," mentioned Alberto Gutierrez, Ph.D., director of the office of In Vitro Diagnostics and Radiological well being on the FDA's coronary heart for models and Radiological well being. "This take a look at might assist clinicians make antibiotic remedy decisions."
The take a look at works by measuring PCT. extreme ranges of PCT suggest a bacterial an infection, whereas low ranges suggest a viral an infection or non-infectious causes.
