Muscle enzyme test?

[Moussemum]

My son has this test tomorrow and I am worried about what they are looking for.Anyone had this test done and been given the all clear?How quick did they get the results?

Just giving an update on the muscle enzyme test.My son got his results back the same day from the hospital.His levels were normal and he doesn’t have muscular dystrophy.He has low muscle tone and attends physiotherapy.He started to walk at 20 months and bum shuffled from 14 months.He is still working on getting up off the floor by himself.Just wanted to inform other parents as there was little on the internet about this.
