Note

If PTT and dRVVT are normal, then no further testing is performed. If PTT is abnormal, Thrombin Time is added. If Thrombin Time is normal, PTT 1:1 mix is added. If Thrombin time is abnormal, Reptilase Time and PTT Heparin Neutralization are added. If PTT Heparin Neutralization is abnormal, PTT 1:1 mix is added. If PTT 1:1 mix is abnormal, Platelet Neutralization procedure is added. If dRVVT is abnormal, dRVVT 1:1 mix is added. If dRVVT 1:1 mix is abnormal, dRVVT confirmation is added. If Platelet Neutralization procedure and dRVVT confirmation are normal or if one is normal and the other not done, Hexagonal Phospholipid Neutralization is added. Additional charges apply.
