Purpose
Although Heparin-induced thrombocytopenia (HIT) is a rare complication of heparin treatment, it results in a high rate of morbidity and mortality, the cumulative rate of thrombosis recurrence, amputation and death approaching 52 % at one month if no specific treatment is initiated. It is therefore vital to diagnose HIT as early and as reliably as possible to permit appropriate management of this rare condition.
During the acute phase of HIT, clinicians and biologists can only suspect this complication with a greater or lesser degree of confidence. Clinical data are not sufficiently sensitive or specific to confirm or refute thr diagnosis of HIT.

| Study Type: | Observational |
| Study Design: | Observational Model: Cohort Time Perspective: Prospective |
| Official Title: | Heparin-Induced Thrombocytopenia : Development and Validation of a Predictive Clinical Score: a Prospective Multicenter Study Under the Auspices of the French Haemostasis and Thrombosis Study Group (GEHT)in Cooperation With the French Association of Regional PharmacoVigilance Center (AFCRPV) |
- the final diagnosis of HIT established by five independent experts in haemostasis and determined by thrombocytopenia and confirmation of HIT by immunological and/or functional tests [ Time Frame: inclusion and 40 days after the inclusion ] [ Designated as safety issue: No ]
- pathogenic nature of anti HPF4 antibodies of IgM and IgA type [ Time Frame: inclusion ] [ Designated as safety issue: No ]
- new biological test detecting HIT [ Time Frame: inclusion ] [ Designated as safety issue: No ]

Inclusion Criteria:
all patients presenting, either during or immediately after treatment:
- thrombocytopenia and/or venous or arterial thrombosis
- for whom a request for biological assessment to check for HIT (anti-H-PF4 ELISA test) is to be addressed to the specialized haemostasis laboratory participating in the study
Exclusion Criteria:
