I have recently started my journey to receive a diagnosis for pidd. i have got back my test results and across the board im low on pretty much every pneumo ab type. what does this mean/whats the treatment?

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your result does not necessarily mean that you have immunodeficiency, unless you received pneumovac.
