KaiMi Biotech (Jiangsu, China) is highlighting its innovative Unow multiplexing drug tests and first-of-its-kind QiDix color-changing swabs at MEDICA 2023.

KaiMi Biotech has launched a series of breakthrough Unow multiplexing drug tests based on its proprietary user-friendly Unow technology platform. These innovative drug tests offer several unprecedented advantages over existing drug tests available in the market to meet the long unmet needs of users. The tests need only a small quantity of saliva sample (80 ml) and a short sampling time (2s) to provide user convenience. A color-appearing indicator tells users if enough saliva has been collected to give them confidence and prevent test inconsistency as a result of sampling errors.

The Unow multiplexing drug tests can be run by a single hand with fewer steps than existing commercial tests and the results can be obtained in 5-10 minutes. Integrated running buffers in the test devices eliminate direct user contact with liquid diluent and reduce potential contamination. The US FDA-approved and CE-marked tests offer excellent detection sensitivity for all the common drugs of abuse that meets the standard cutoffs for most regions around the world. The tests offer great flexibility for customization for detecting different combinations of drugs in a single device to meet the customer’s specific needs.

At MEDICA 2023, KaiMi is also presenting its flagship product, the QiDix color-changing swabs. These swabs are immobilized with a proprietary color indicator to help users ensure that enough samples have been collected. The US FDA-approved QiDix swabs are particularly useful for collecting samples for babies and kids, or patients who have challenges collecting samples by themselves. The indicator can be triggered by body fluids such as saliva, nasal secretion, sweat, tears, and urine, but not by water. The color change will not fade once triggered and the color indicators consist of only safe food-grade ingredients. A number of types of QiDix swabs are available, ranging from flocked swabs, woven swabs, and cotton swabs.
