The TaiDoc TD-4209 Clever Chek is an automatic blood glucose meter. The accuracy of its blood glucose measurement technology has yet to be proven to MDR requirements. Blood glucose measurements are taken from the finger. It is intended for self-measurement and home use. This device has been discontinued by the manufacturer but may be available through certain outlets.

The technology used in the TaiDoc TD-4209 Clever Chek, to measure blood glucose, has failed in a clinical validation study, in a general population, according to a recognised standard protocol, as published in a peer-reviewed publication. However, it was also assessed in another study, but the results have not been published and cannot be verified.
