The authors of February's Clinical Case Study provided us with three exclusive questions that will not appear in the published version of the Case. We'd love to hear your answers to these questions in the comments section.

1) What are the major pre-analytical factors affecting an individual's CK level?

2) What is Macro-CK, how is it diagnosed and what is the clinical significance of it?

3) In an individual who is on a statin, at what CK level should we consider stopping the statin, and what should we do next?
