I've had blood work with both and CEE clearly registers much higher in my blood much to my doctors horror.
That's interesting. It could almost be an advertisment FOR the CEE. As far as I know there is no test for Creatine in the blood but only for the end product - creatinine. A lot of time doctors see increased levels of this and they panic thinking kidney malfunction when in fact it mean nothing of the sort and only that your muscles are using more creatine. That's one of the reasons creatine supps are accused of damaging the kidneys which is of course bullshit. The fact is you take a huge muscular guy who has NEVER used creatine and he'll show you elevated levels of creatinine, just the way he should.
It's funny that CEE should show higher levels.
I looked at the post Verb made on blood test levels and got this:
Creatinine is a byproduct of creatine phosphate, the chemical used in contraction of skeletal muscle. So, the more muscle mass you have, the higher the creatine levels and therefore the higher the levels of creatinine. Also, when you ingest large amounts of beef or other meats that have high levels of creatine in them, you can increase creatinine levels as well. Since creatinine levels are used to measure the functioning of the kidneys, this easily explains why creatine has been accused of causing kidney damage, since it naturally results in an increase in creatinine levels.
However, we need to remember that these tests are only indicators of functioning and thus outside drugs and supplements can influence them and give false results, as creatine may do. This is why creatine, while increasing creatinine levels, does not cause renal damage or impair function. Generally speaking, though, increased levels are indicative of urinary tract obstruction, acute tubular necrosis, reduced renal blood flow (stemming from shock, dehydration, congestive heart failure, atherosclerosis), as well as acromegaly. Decreased levels can be indicative of debilitation, and decreased muscle mass via disease or some other cause.
Adult Male 0.6-1.2 mg/dl
Adult Female 0.5-1.1 mg/dl
A high ratio may be found in states of shock, volume depletion, hypotension, dehydration, gastrointestinal bleeding, and in some cases, a catabolic state. A low ratio can be indicative of a low protein diet, malnutrition, pregnancy, severe liver disease, ketosis, etc. Keep in mind, though, that the term BUN, when used in the same sentence as hamburger or hotdog, usually means something else entirely. An important thing to note again is that with a high protein diet, you'll likely have a higher ratio and this is nothing to worry about.
