What does a CPK level of 175 mean?
Patient: Hello.  What does a CPK level of 175 mean?  I have seen a geneticist who ordered this test and it came back high.  I have a mitochondrial disease, hypothyroidism, fibromyalgia, tachycardia, restless leg syndrome, asthma, pulmonary hypertension.  I am a 44 year old female.  I don't know if that matters. Doctor: Hi, thank for posting.Phospho-creatine kinase is an enzyme that takes part in tissue energy production. CPK is found in tissues that consume high energy. It is found in high amounts on skeletal muscle, brain, photoreceptor cells of the retina, hair cells, inner ear, spermatozoa, smooth muscle and on myocard.CPK level of 175 is in its maximal limit.High level of CPK shows tissue damage of the above organs.To determine the organ that is damaged, you need a CPK isoenzymes test.So you should consult your geneticist.Regards.Dr. Behar.
