However, with earlier recognition of the associated symptoms, the clinical manifestations are likely to be more heterogeneous and represent an evolving spectrum of disease. ДЄll guidelines rapidly identify VITT in patients with the complete triad of thrombocytopenia, thrombosis and elevated D-dimers after ChAdOx1 nCoV-19 vaccination. Urgent medical evaluation for TTS is indicated. Risk of death and serious outcomes of COVID-19, including thrombosis, far outweigh risk of TTS possibly associated with. Thrombosis with Thrombocytopenia Syndrome (also termed Vaccine-induced Thrombotic Thrombocytopenia) Incidence is extremely low.Diagnosis of VITT is based on the occurrence of thrombocytopenia (low platelets) and blood clots (thrombosis diagnosed radiographically or clinically), and laboratory evidence of (or risk for) clot formation (elevated D-Dimer, decreased fibrinogen, markedly elevated anti-platelet factor four antibodies) occurring within 3 weeks of.Addition of high dose heparin inhibits OD.Marked positive PF4 IgG ELISA with high OD.

Low levels of antibodies are common in some clinical settings, e.g.

For HIT diagnosis, PF4 ELISA has excellent NPP but mediocre PPV.

Investigations involve full blood count, coagulation study, PF-4 antibodies and imaging to confirm the thrombosis and to look for the extent of the involvement. Most common presentations include symptoms of thrombosis and thrombocytopenia.
