In patients suspected of having PPGL, biochemical testing via measurement of plasma free metanephrines or urinary fractionated metanephrines is recommended. The use of liquid chromatography with mass spectrometry or electrochemical detection methods is suggested over other laboratory methods. Patients with a known germline mutation that predisposes to PPGL should undergo periodic biochemical testing. [64]
