A CK test should be carried out if:
|IF CK IS ELEVATED|
(Normal range is generally up to 250 U/L*)1
|Refer to neuromuscular specialist for Duchenne muscular dystrophy gene testing6|
|IF CK IS NORMAL||Does not rule out other neuromuscular disorders1|
*The normal CK range is generally up to 250 U/L. Absolute values may differ between laboratories.1
Prompt CK testing can help to achieve the correct diagnosis and bring reassurance to families1,9
If you suspect a neuromuscular disorder, order a CK blood test.1
• Elevated CK levels reflect muscle damage, and are a sign of certain neuromuscular disorders1–5
• A CK test is quick, simple and inexpensive1,3,6
All patients who have elevated CK levels should be promptly referred to a neuromuscular specialist.8,11
Normal or mildly elevated CK does not rule out neuromuscular disorder. If a patient has missed motor milestones, they should also be referred to a neuromuscular specialist.8
A neuromuscular specialist can then:2
Identify the child’s exact mutation2
Confirm Duchenne muscular dystrophy with a genetic diagnosis and identify the specific mutation causing the disease2
Define best management options2
Decide upon appropriate treatment and interventions to help delay disease progression2
Prompt CK testing can help to achieve the correct diagnosis and bring reassurance to families.3,13 Learn more about CK testing here.
