{"HLA-B*15:02 and HLA-A*31:01 genetic status may be predictive of a severe cutaneous adverse reaction to carbamazepine. This patient is HLA-B*15:02 negative. There is no reason to alter carbamazepine therapy based on the HLA-B*15:02 result. Because a HLA-A*31:01 genotype does not appear to have been ordered for this patient, use of an alternative agent may be recommended. Please consult a clinical pharmacist for more information."}
