AST (Alternate Site Testing) means using other parts of the body other than the fingertips to obtain blood for blood sugar testing. For example, you can take a blood sample from anywhere other than the fingertips, including the palm, the upper forearm, the abdomen, the calf and the thigh.
The AST video discusses what AST is, why you should consider alternate site testing and which places on the body can be used for AST.
