Immediate CBC with platelet count and imaging for thrombosis based on symptoms.
If thrombocytopenia or thrombosis are present, recommend urgent consultation from hematologist with expertise in hemostasis. Avoid use of heparin until TTS has been ruled out or until an alternative other plausible diagnosis has been made.
Initial work-up (a normal platelet count is less concerning for TTS*):
CBC with platelet count and peripheral smear
Imaging for thrombosis based on signs/symptoms
PF4-ELISA (HIT assay); draw blood prior to any therapies
Fibrinogen and D-dimers
