Abstract: A system for determining concentration of a predetermined osteoarthritis biomarker in a urine sample includes first cell and first limiting elements, a quartz crystal microbalance (QCM) sensor device having a sample contacting side, and a monitoring device. The first cell element has a sensor confronting side formed with a recess portion. The first limiting element is disposed at the sensor confronting side, is disposed to surround the recess portion, contacts the sample contacting side, and cooperates with the recess portion and the sample contacting side to confine a sample receiving space for receiving the urine sample. The QCM sensor device includes a quartz resonator and an antibody applied to the quartz resonator and capable of binding with the biomarker, generates a concentration signal corresponding to mass of the biomarker that binds to the antibody, and is coupled to the monitoring device to provide the concentration signal thereto for processing thereby.
