Fig. 2From: Evaluation of the diagnostic potential of urinary N-Acetyltyramine-O,β-glucuronide (NATOG) as diagnostic biomarker for Onchocerca volvulus infectionNATOG levels in urine from healthy volunteers from Belgium, both non-spiked and spiked with 50 μM NATOG. NATOG levels were analyzed with the LC-Fluorescence assay. Recovered NATOG is calculated by subtracting the endogenous level (non-spiked) from the total (spiked) concentrationBack to article page
