If you've had your total IGA levels done twice in the past and they were normal, it isn't likely that will change. It's my non-doctor understanding that you are either total IGA deficient or you are not, and this will not change over your lifetime.

As a clinician, I don't agree with that. I think there are some people who are indeed genetically low IgA (and that's what mainstream medicine sees as 'low IgA'), but I see levels of immunoglobulins fluctuate all the time depending on how the immune system is doing, if infections are present etc etc, so always worth checking IMHO. Certainly SIgA, the mucosal IgA goes up and down all the time, esp if a person is stressed, getting poor sleep etc. 

I'm in the UK so we may do things differently, but my take on it would be that it looks like your IgA antibody is on the low-normal side so the doctor is, quite rightly, suggesting the result might suggest total IgA production is low. If it's low, then the 'real' result might be a lot higher in reality. They should really have done an IgA total test at the same time, but they rarely do. It's nice to see a doctor note it though - although not suggest a follow up IgA Total test! Hope that helps.
