Abstract
A medical device verification system for an extracorporeal photopheresis procedure comprises a reusable irradiation device comprising a UV light source and a scanner. A fluid circuit comprises a disposable cell suspension container having a photo-reactive label comprising an identifiable code. The identifiable code is unobscured when the label in a first state and is obscured when the label is in a second state. The irradiation step is performed by irradiating the disposable cell suspension container for a predetermined period of time at or above the threshold UV irradiation level. A second input is received from the scanner during the irradiation step, the second input comprising identification of a state of the label. A response action is provided if the first input comprises identification of the second state of the label and/or if the second input comprises identification of the first state of the label.
