What is the maximum recommended tourniquet time during venipuncture?

Prolonged tourniquet time causes venous stasis, which concentrates blood components and can alter levels of certain analytes, potentially skewing test results. To minimize these pre-analytical changes, keep the tourniquet on for no more than one minute (sixty seconds). If you can’t obtain a sample within that window, release the tourniquet, allow normal flow to resume, and try again. This practice helps ensure more accurate and reliable results for routine venipuncture specimens.
