I received yesterday my results for
Immunoglobulin A : 79.5 (range 70-400)
Immunoglobulin G : 698.7 (range 737-1607) depressed
Immunoglobulin M : 257.8 (range 40-230) elevated
I don't have a clue what to do with this result. So does my GP

.
Don't have subclasses done.
Thank you if someone understands what it may indicate about what is going on with the immune system
