First: Ganga Ram Hospital starts COVID Vaccine-Induced Thrombotic Thrombocytopenia testing facility

New Delhi: Delhi's premier Sir Ganga Ram Hospital has become the first centre in India to perform the confirmatory tests for Covid Vaccine-Induced Thrombotic Thrombocytopenia (VITT).

According to Dr. (Prof.) Jyoti Kotwal, Chairperson, Department of Hematology, Sir Ganga Ram Hospital, "Since the Index case of June 2021, we have received and diagnosed six more samples of VITT. Interestingly, five samples came from Kerala and one from neighbouring hospitals of Delhi." These samples came by courier to Sir Ganga Ram Hospital and due to timely diagnosis and advice for therapy, the lives of all other patients of VITT could be saved, she added.

Rare cases of blood clots and low platelets after receipt of adenovirus vector COVID-19 vaccines have been reported and are referred to as VITT or Thrombosis with Thrombocytopenia Syndrome (TTS).

Cases have been reported since early 2021 from Denmark, United Kingdom, Germany, and Canada and on 11th August 2021, the UN issued guidelines for diagnosis and management of TTS.

The gold standard confirmatory test is the presence of heparin dependant platelet aggregation of normal platelets by patient's serum in presence of a low dose of heparin. The Hematology Department at Sir Ganga Ram Hospital under Professor Jyoti Kotwal is the only center in India doing the gold standard Platelet aggregation test in the country. The samples of serum of suspected VITT are being received through courier and prompt diagnosis is made within 48 hours of receiving samples
