Testing for Blood Clots: What You Need to Know About VTE Screening
Why It Matters
Testing for VTE can uncover hidden risks and guide treatment. Here's how healthcare providers approach it.
Contents
Initial Testing Methods
To evaluate VTE, doctors start with a complete history and physical exam, looking for signs of surgery, trauma, or family history of clots. Routine lab tests like a blood count and coagulation studies help identify potential risk factors. Imaging studies, such as ultrasounds or CT scans, confirm the presence of clots.
Advanced Testing for Inherited Disorders
In some cases, further testing for inherited thrombophilia is necessary. This includes checking for deficiencies in proteins that prevent clotting and genetic mutations like Factor V Leiden. Such tests are usually reserved for younger patients or those with a family history of VTE.
Testing for Malignancy
When VTE occurs without a clear cause, doctors might test for hidden cancers. This involves basic lab tests and age-appropriate cancer screenings. In high-risk patients, more extensive testing, like CT scans, is considered.
FAQs

Why screen for cancer with VTE?
Unexplained VTE might indicate hidden cancers needing investigation.
What is Factor V Leiden?
A genetic mutation increasing the risk of blood clots.
