An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay, After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.
