I am so disappointed. My CD57 is lower than it was in November. It was 54 now 42...what does that mean?
And although not extremely out of the norm. My MCHC was slightly low (anemia) and my BUN/Creatine was slightly high.
the frustrating thing, is this was taken when I was feeling pretty good. before my latest herx (and just after the cortisone shot in my foot. but my sed rate was normal for the first time in for ever )
will talk to llmd next week...but of course I am wondering if I could be doing my kidneys harm on my latest protocol (ceftin/cipro/ 2wk on/off flagyl pulse) And where does the anemia come in?
My numbers are just a point off the normal.
When is the cure worse than the disease?

One point outside the normal range is nothing to think twice about. That's why your doctor isn't thinking about it at all.
The normal range is based on the normal curve. They want a certain percentage of the population (I think it is 66%) to be within the normal range. So, after looking at thousands of results, they make up the normal range. Your normal is one point outside of that.
It isn't that if your number is above X, then you are sick!!! Not at all. It is that most people are within the normal range. Same for body temperature, etc. But, your normal may deviate a little from the general population. Doesn't mean you are sick at all.
Besides, with creatinine, they are estimating your creatinine level by making assumptions about the amount of muscle you have. They make these assumptions based on your age and sex. So, if you have a wee bit more muscle than they expect, your creatinine will always be outside the normal range.
My husband's is outside the normal range because he lifts weights. To get his true creatinine level, he had to collect his urine for 24 hours. It was tested and he was told by a nephrologist that his kidneys were perfectly normal. But, according to the "normal range" he was in 3rd stage kidney failure.
The nephrologist took one look at my husband when he walked in the room and said, "I see you are in good shape (talking about his muscle mass). You don't ever have to come back to me."
So, now you know why your doctor thinks nothing of being one point outside the range.
Look up the creatinine test on the net and you will see what I am talking about.

Thank you joala, for bumping this up i notice you do that for a lot of people. Thank you. Thank you lpkayak and TF for making feel better. I did try the google. I did not find anything that specific. I was just wondering if this could be caused by the abx? (certainly muscle mass is not my problem unfortunately).

Yep. Here are some references for you.
"Muscular young or middle-aged adults may have more creatinine in their blood than the norm for the general population."
"The actual amount of creatinine that a person produces and excretes is affected by their muscle mass and by the amount of protein in their diet. Men tend to have higher creatinine levels than women or children."
"An eGFR test may not be as useful for those who differ from normal creatinine concentrations. This may include people who have significantly more muscle (such as a body builder) or less muscle (such as a muscle-wasting disease) than the norm, those who are extremely obese, malnourished, follow a strict vegetarian diet, ingest little protein, or who take creatine dietary supplements. Likewise, the eGFR equations are not valid for those who are 75 year of age or older because muscle mass normally decreases with age."
