CRP blood test parameters

[pberggren1]

The CRP and ESR were both over the highest values they report at that lab. It was about 2 or 3 years ago I think. I think your CRP and ESR are within range and nothing to be concerned about too much. Always go by symptoms first. How do you feel? But having said that, one must always do regular labs as well. I know a few on here that don't but they really should. Sometimes labs can indicate a flare up. It caught an early flare for me once.

Thanks Phil
What are you current CRP and ESR and what MTX and PRED are you on now?

My CRP is 18 and ESR is 6 from yesterday. I am Imuran but went off it on my own a couple weeks back because of lung infection. I will start it again tomorrow at 50mg.

My CRP reads as 18.5 and the average is 0.00-10.0 mg/L
Pathology reports as mild inflammation only.

ESR is 33 and the average is 3-12 mm/hr

I would think that yours are within an acceptable range Stephen

Hi Pete
What is that level in mm/1st hour5 (whatever that means)

I think you're confusing CRP and Sed Rate. At OSU, the standard for Sed Rate is <20 mm/hr.

Hi Pete many thanks we call the sed rate ESR in Ireland and the normal range is 5-19 mm/hr
The CRP is measured in mm/1st hour5 ( don't know what the "5" is could be typo) was 4-12mm now altered to <3
Any light on that stuff?

I googled this, which I'm sure you have too.
Lots of results come up with CRP mm/1st hour but there is nothing with a 5 on the end.
It is probably a typo like you say or maybe it means they tested it 5 times ??

I guess you could phone the pathology dept and ask them if it is a typo or not

You could take your lab report to the lab that drew your blood and ask them to explain it or check with your dr's office. I'm sure they would be more than willing to help you understand it. Everything here is going to be confusing as everyone is from a different area/country. Sometimes it's like comparing apples to oranges. Google it for your country also. That's what I do a lot of times when I get my blood report.

Steph,

I'm clueless about how your CRP is measured. CRP is a measure of the volume of the protein in the blood. Sed rate (ESR) is a measure of distance over time.

The values assigned to each measure vary from not only country to country but from hospital to hospital in the same local. I thought I would chart my labs but it would make no sense since the ranges of normal varied.
