What is a common indication for thrombophilia evaluation?

A common indication for thrombophilia evaluation is the occurrence of two idiopathic venous thromboembolic (VTE) events. This situation raises a concern about an underlying genetic or acquired thrombotic disorder that predisposes an individual to developing blood clots. When a patient experiences two separate incidents of VTE without an obvious provoking factor, healthcare providers may recommend a thrombophilia workup to identify potential risk factors. This evaluation can help guide further management and prevention strategies for future VTE events, especially given the potentially serious consequences of recurrent thrombosis.

In contrast, a single idiopathic VTE event typically does not warrant an extensive thrombophilia evaluation, as many individuals may develop a VTE due to transient risk factors. Similarly, a VTE occurring at an older age may not necessarily indicate a thrombophilia evaluation, as age can be a risk factor on its own, and it does not directly imply a genetic predisposition. A lack of a history of recurrent VTE also does not indicate a need for evaluation, since the absence of multiple events suggests that the individual may not have an underlying thrombotic tendency.
