You can obtain capillary blood for blood glucose testing not only from the fingertips, but also from other sites (palm, forearm, upper arm, calf or thigh), so-called alternative site testing (abbreviated as: AST). To be able to obtain capillary blood from other sites, you have to replace the regular cap by a special cap, the Accu-Chek Multiclix AST cap. Consult your healthcare professional beforehand if you want to use blood from alternative sites for your blood glucose test. Please follow the instructions of use of the AST Cap insert.
