Can anybody explain the difference between the terms "chem 7" and "chem 12"?
Comments  
Hi Pagal

"Chem 27" is an Am. medical term. They seem to have 2 biochem. blood tests, a Chem 7 (measuring 7 values) and a Chem 20 (measuring 20 values). I have not been able to find a "chem 12" (or even a chem 5, in case Chem 12 = chem 7 + chem 5) maybe Melodie can help us out

Do you want to know what's measured in chem 7 & chem 20?
Hi Abbie

Thank you for trying to help me out. I am a proof reader in a Medical Transcription Company and it is good for me if I know these topics, at least what actually these words mean.

As you said, let us wait if Melodie can help. Thank you once again.

Hi Pagal,

I can tell you what chem 7 / 20 tests, if that helps.
Hi Abbie

I will be very thankful to you if that happens....

Hi Abbie

You are really wonderful. You don't hesitate to help others and you have a definite answer for every query.

I would like to know about you, master.

Where are you from? What do you do?
Hi Pagal,

I'm just a vistor here like you. I'm English, and I live in England, and I'm a woman. I have trained for and done lots of things, but I don't go out to work now, although I'm always very busy. Emotion: smile
