What exactly does low SIgA mean, besides depressed immune system, treatment?

I got my Diagnos-Techs test back and found

Total Salivary SIgA 9 (depressed) normal 25 - 60

Total Intestinal SIgA (Stool) 16 when should be 400 - 880

Also on the test was Gliadin intolerance WHICH I CUT OUT LIKE 6 MONTHS AGO,

other tests found 0 parasites, and...

we are already on my second round of anti fungal program,

and today I did my 2nd Liver Flush and got ~20 stones out and I had a headache (hopefully this is a herx/die off reaction) (1st flush 0)

in the middle of oral, suppository, chelation of lead (high levels on urine challenge test), tungsten (""), and mercury (retention, super low levels on hair, mid "normal" levels on urine challenge)

No helicobacter

As far as I know I eat super duper healthy (all organic etc)

I very rarely get sick (which I know could mean my immunity has given up)

Anyone have any ideas on what this means, does it really mean severely depressed immune system? Either way what are possible root causes?

Could I have lyme disease? (waiting on test results but would still like to know your thoughts)

I have all sorts of old health symptoms including fatigue, difficulty concentrating, allergies, urinary frequency, very slow recovery time. Tweet
