Diagnosis and Management of VITT


Rare cases of thrombosis with thrombocytopenia have been reported following vaccination with the Johnson & Johnson/Janssen COVID-19 vaccine. For patients that develop thrombocytopenia and/or thrombosis within days post-vaccination with COVID-19 vaccines, and VITT is suspected, Versiti offers several testing options.

For the latest recommendations on diagnosis and management of suspected VITT, please refer to the American Society of Hematology (ASH), International Society on Thrombosis and Hemostasis (ISTH), and Centers for Disease Control (CDC) official guidance.
