Do you know why EDTA tubes cannot replace Sodium Fluoride tubes to do glucoes test ?

1. Anticoagulant effect: EDTA is an anticoagulant that is used to prevent blood from clotting. However, EDTA can interfere with the glucose measurement process, leading to inaccurate results.

2. Glucose consumption: EDTA can cause the cells in the blood sample to continue consuming glucose, even after the blood has been drawn. This can result in a lower glucose reading compared to the actual glucose level in the body.
