About this test

Understanding the DRVVT Screen Ratio

The Dilute Russell Viper Venom Time (DRVVT) screen ratio is a specialised test used to detect the presence of lupus anticoagulant (LA), an antibody associated with clotting disorders.

What a Normal DRVVT Screen Ratio Indicates

A DRVVT screen ratio of less than 1.20 is considered normal. This result typically suggests that lupus anticoagulant is not present or is not detectable using this specific method. However, it’s important to note that LA may still be identified using alternative testing methods.
