Should patients who experienced Neuroleptic Malignant Syndrome (NMS) or Serotonin Syndrome be tested for MH?

For an explanation of these syndromes, go to the NMSIS Website. There does not appear to be a relation at the genetic level between MH and these syndromes. Different drugs than anesthetics cause these conditions through a different mechanism than for MH, although dantrolene may be effective in the treatment of NMS.
