Does anyone know how likely errors are in bloodtests? I am still puzzled by what happened to me in the past few months.

I had a bloodtest done, and the results came back and indicated that I had massive levels of inflammation in my body. I was told absolutely not to run; walking was fine.

For about one month, I saw different doctors and had tests done. Nothing showed any problems. New bloodtests were taken. I was taking cortisone at this time.

The new bloodtests showed optimal results. The dr. thinks there may have been an error in the first test. I was ordered off cortisone.

How likely is it that there was a false reading? Does this occur frequently?

Third time's a charm?

I would guess it happens more often than we're led to believe.

Could it be that your inflammation level was down because of the cortisone?

This could be the case. Also, depending on what diagnosis they are questioning, there could be other tests that they could run.

Humans label the tubes and run the tests so its always possible they could be wrong but there are lots of controls and cross checks in place so it doesnt happen.

Did you have symptoms prior to the blood test or was this "random" bloodwork?

while humans label the tubes, that is becoming much less of an issue anymore. more than likely there was either something wrong in either processing the sample or the next most likely scenario is an interfering substance in your blood, medication is a culprit there.

was the first test after an endurance or a heavy training session?

also were you way out of whack? normal values are an average of a population, so if you are out the outside of the bell curve you are considered "out of normal range".

could be at the end of a reagents lifespan which could have effects

could be above the Doctors preferred values and not necessarily the Lab's normal values (least likely but i've seen it with specialty Docs.)

I promise you, my fellow New Yorkers, that Mayor Giuliani will do everything possible to cleanse this city of this falsified non-fat yogurt.

I had no reason to believe that I was sick; I had a hamstring injury and some hip pain that was not healing very well, and therefore went to see a specialist.

Yes, I think the cortisone could have masked the inflammation, but it was "massive Inflammation" to the point where they thought I might have muscular dystrophy, at least the initial signs. But it puzzled them that I managed to qualify for Boston and did run Boston in the spring.

They should have rerun the bloodwork at that time if it seemed that odd. I have had a lot of patients have questionable bloodwork results, it seems quite common.

Although the repeat tests show that the numbers are down, I have the feeling that either you healed, or the drugs (steroids) are masking the inflammation, which is what they are supposed to do.

You didn't tel us the test name, CRP or Sed Rate(ESR) so I'm gonna assume the test was in fact the CRP. Their are some things that will interfere with the testing, but it would be highly likely that that is the case.

It is possible that someone mislabeled a tube or resulted the specimen wrong, but again, I doubt it since things are so automated.

Many things can cause an elevated CRP. It is very nonspecific. The physician should use those results and the results of other tests together to come up with the best course of treatment.

CRP was over 3,000; this was the problem. Sed rate was 1.

They did tests for lyme disease, polymyaglia rheumatica, lupus, thyroid.

A muscle biopsy (needle) was done, too, and X-rays were taken.

The rheumatologist told me that he would do the test again when I was off the cortisone; but he OKed me to run again, based on the second bloodtest.

Funny thing is, I am running better than ever after a 6-7 week hiatus from running, with only long walks.
