Which laboratory test is used to measure the effectiveness of warfarin sodium therapy?

The blood test, called prothrombin time (PT or protime), is used to calculate your International Normalized Ratio (INR). Your INR helps your healthcare provider determine how well warfarin is working to prevent blood clots and if the dose needs to be adjusted.

What laboratory values are the most important for the nurse to monitor for heparin?

When assessing therapeutic levels of unfractionated Heparin, two laboratory tests are available; the Activated Partial Thromboplastin Time (aPTT) and the Anti-Factor Xa Assay. The aPTT has been the gold standard for monitoring IV heparin for more than 50 years. It is cost-effective and familiar to most personnel.
