Question

Which of the following offers standardized lab values indicating the blood's ability to coagulate for patients who are taking anticoagulant medications?

1) Prothrombin Time (PT)
2) Partial Thromboplastin Time (PTT)
3) International Normalized Ratio (INR)
4) Activated Partial Thromboplastin Time (aPTT)

Answer 1

The International Normalized Ratio (INR) is the standardized lab value that indicates the blood's ability to coagulate for patients taking anticoagulant medications.

Step-by-step explanation:

The standardized lab value that indicates the blood's ability to coagulate for patients taking anticoagulant medications is the International Normalized Ratio (INR). The INR measures the speed of a specific coagulation pathway, comparing it to normal. An increased INR indicates that it is taking longer for blood to clot.
