Hi there, just wondered if anyone out there knew what 'CV3' is. Just got the results from a full immune profile from clinic and apparently my CV3 is above normal. Am on holiday and phone call from clinic was brief, so now I'm wondering what it means! They mentioned I might need to be treated with steroids or IVIG. Perhaps CV3 has another name, cos I'm not finding much when I do a Google search. Perhaps there are some experts out there who can shed some light for me? Much appreciated.
