Discrepancy in WBCT results at 20 and 30 minutes in a patient with an Echis ocellatus envenomation. Transient, asymptomatic resumption of coagulopathy at H24 by WBCT30 alone. This patient (case no. 12) presented to the hospital less than 1 h after an Echis ocellatus bite to the 5th finger of his right hand and was already experiencing completely incoagulable blood (Grade 2) at both reading times despite the absence of any bleeding from the bite site or elsewhere. Two vials of antivenom were administered at H0 and additional two vials were given at H3 when assessment revealed a new onset of gingival hemorrhage in addition to persistence of abnormal WBCT results. Bleeding ceased within an hour and WBCT20/WBCT30 were both normalized during the next evaluation at H6. There was a brief resumption of coagulopathy by WBCT30 at H24 that was inconsistent with the overall picture of clinical improvement and resolved 24 h later at H48. WBCT20 was restored permanently at H6
