A surgical sponge and fluid monitoring system and method are provided. The system (100) includes a support ring (104) for securely supporting a container (101) with at least one port opening (206) for placing sponges (204) into the container through the at least one port opening. The support ring includes RFID communication circuitries (305, 307)that interrogate an RFID device (205) in the sponge (204) and an RFID device in the container. The support ring is mechanically linked to a load cell (706, 1329) in the system. The processor (1302) reliably detects when a sponge is placed into the container through the at least one port opening, identifies the type of sponge placed into the container, counts the number of sponges in the container, sorts the types of sponges, and calculates fluid loss for a patient in a surgical procedure. A user interface (1308, 114) keeps the medical professionals informed.
