ABORhCard Credit Card-Sized Blood Group Determinator

Micronics of Redmond, Washington has gained FDA clearance for marketing its ABORhCard, a credit card-sized device that determines blood group and Rhesus factor status. The card contains anti-A, anti-B and anti-D antibodies printed into discrete microfluidic channels. The device gives fast results, within minutes, and can be stored at room temperature. However a buffer needs to be added after storage to rehydrate the antibodies. It was developed with help of funding by the U.S. army for use in battlefield and emergency situations. However, for now the device is marketed for personal educational and informational purposes only, as it has not been cleared for medical use.
