Does anyone know what "rca positive" could mean?

I had a letter from my diabetes consultant and it says "GAD antibodies positive / rca positive".

I know about GAD but does anyone know what rca means?

Also, it says my c-peptide was 479. Every c-pep range I've read online is expressed to be much smaller as nanograms etc. - what on earth does 479 mean?!

Thanks!
 
There are so many abbreviations used in pathology, you're probably better off getting the results explained by your doctor than trying to work out what it means by yourself.
 
are you sure it didn't say brca positive as rca positive is to do with wiring up speakers according to google
 
As Indy says you really need to ask about that one If it is rca then its not a test I've heard of related to diabetes. However, if it was handwritten (or mistyped) it could be ICA ;islet cell antibodies. These are very commonly tested for as they are alongside GADA commonly found in T1 https://labtestsonline.org/understanding/analytes/diabetes-auto/tab/test/
According to one article C-peptide is commonly reported in nmol/l, pmol/l or ng/ml. .. 1 nmol/l = 1000 pmol/l = 3 ng/ml (the article also discusses the validity of the test and cut off points) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3748788/
 
Thanks everyone. @phoenix - you hit the nail on the head with ICA, I spoke with the nurse who typed up the letter and she did indeed mean "ica" and not "rca". As for the c-peptide, she didn't know, but I assume the 479 figure is pmol/l which would be 0.479 nmol/l which would make sense.
