چکیده
A 76-year-old woman was admitted for cardiac decompensation, hypertension, and renal failure. To explore her chronic hypertension, urinary fractionated metanephrines were quantified. Fig. 1A shows the chromatogram of the patient’s urine, and Fig. 1B shows the chromatogram of a calibration standard. A very large methoxytyramine peak was observed (Fig. 1A, black arrow). The peak signal was saturated, representing a concentration greater than 16 200 nmol/L (0 –1 600 nmol/L).
