Muscle Biopsy CHCT

The CHCT is the standard for MH diagnostic testing and is used to determine a patient’s susceptibility to MH.*

Patients must be referred to specialized CHCT Centers in order to have the special biopsy for CHCT performed.

MH experts generally feel a child less than 10 years old is not a good candidate for CHCT testing.

Muscle biopsies for CHCT must be performed at one of the designated CHCT testing centers because the test must be performed on fresh tissue.

CHCT TESTS CANNOT BE PERFORMED BY MAIL. Patient must travel to an approved testing center.
