Some people routinely check IgA levels prior to giving IVIG. Others think this is outdated. Can anyone post about their experience? Has anyone caught IgA deficiency doing routine IgA levels? Shouldn't screening questions for IgA deficiency be enough? |

I have attended talks by some of the leading experts in CIDP (whose names I will not mention), who state that they do NOT check IgA levels prior to giving IVIG, because it is so rare to have IgA deficiency. In addition, testing for this is tricky because there is a gradual production of IgA levels as you get older, so your lab would need to have age matched control values. |
