When To Perform a Mixing Study

A mixing study should be considered when a patient has a prolonged PT and/or aPTT along with:

  • no history of heparin or warfarin therapy
  • no history of liver disease

It is also essential to first verify that a correctly collected sample (free from clots) with a proper blood to anticoagulant ratio has been obtained.
