Recurrent Miscarriage/Fetal Demise Profile (Esoterix)
Also known as: Obstetric Complications Profile
Use
This profile is intended to evaluate a range of coagulation, thrombophilia, autoimmune, and genetic risk factors associated with recurrent miscarriage or fetal demise, including clotting factor mutations, lupus anticoagulant, antiphospholipid antibodies, homocysteine levels, and natural anticoagulant activities. It supports clinical investigation in women with obstetric complications or history of fetal loss.
Special Instructions
Informed consent is required for New York patients. If results are abnormal, activated partial thromboplastin time (aPTT) will reflex to immediate aPTT mixing studies; additional charges and CPT codes may apply.
Limitations
This procedure may be considered by Medicare and other payers as investigational and, therefore, may not be payable as a covered benefit for patients.
