They assessed levels of 3-phenoxybenzoic acid (3-PBA) in urine samples provided at the time of the survey using analytical chemistry techniques (high-performance liquid chromatography, electrospray chemical ionization, and tandem mass spectrometry). Patients with neuropathy typically present with symptoms of pain, tingling, or numbness in their feet, consistent with dysfunction affecting the longest and largest fibers of the peripheral nervous system (PNS).
