A CPK blood test that shows persistently high levels of creatine kinase could be an indicator of an autoimmune condition. Alas, afederal judge tossed the lawsuit, saying Simpson didn't provide enough hard core data to prove the potential dangers of trans fats. But unlike Cp, Cpk compares the distance from the process mean to the closest specification limit, to about half the spread of the process (often, the 3-sigma spread). my process nut tightening process (we measure here torque), action taken incase the cpk come under 1.33, I reduce the speed and it will go above 1.33.
