Is the "U" for "units"? - If so, do you know anthing about how much one unit is?

Also, what is CK-MB?

Hi,

I have the same question as labtek. CK-MB is Creatinine (Phospho) Kinase-Muscle Brain isoenzyme. It is a marker used to help with diagnosis of several cardial pathologies, like acute myocardial infarction. From one lab I have normal ranges 0-24 Unit/L, while another lab is giving 0- 4.55 micrograms/L. I would like to know how to convert from Units to micrograms

Hi everyone.

You need to find out how much a "unit" is for your particular substance.

"Units" are measured by the biological activity they have, and can be very different, even for similar compounds.

One unit of something will be a specific weight, but you may need to get this information from the manufacturer.

1:1 Numeric Correlation to other Methods is NOT the Recommended Approach. Some Assays measure Mass of CKMB using the Unit ng/mL and some Assays measure the activity of CKMB using the Unit IU/L.
** THERE IS NO CONVERSION FACTOR TO CONVERT MASS UNITS TO ACTIVITY UNITS.

Haroon #7 and Tara #8, we can't do this conversion, you need to find out how much 1 unit weighs. It is different even for similar compounds.
