Methods and systems for detecting the presence of moisture and/or foreign matter in a lumen of a medical device. An illustrative method may comprise coupling a first probe to a first end of a lumen of a medical device, the first probe comprising a first electrode and a first electrical connection extending proximally from the first electrode, coupling a second probe to a second end of the lumen of the medical device, the second probe comprising a second electrode and a second electrical connection extending proximally from the second electrode, transmitting an electrical signal through the first and second electrical connections, determining a direct current (DC) voltage drop between the first and second electrical connections, calculating a surface resistivity of the lumen based on the DC voltage drop, determining if the calculated surface resistivity is below a threshold surface resistivity, and providing a test status notification.
