In heparin-induced thrombocytopenia (HIT), how long does it take the platelet count to recover after stopping heparin?

By William Aird

Platelet count recovery occurs within 7 days in 90% of cases. Functional assays become negative at a median of 50 days after heparin is suspended, while circulating anti-PF4/heparin antibodies are no longer detectable by immunoassay at a median of 85 days.
