I usually don't reply anymore on this forum but your story really affected me.
I am a patient at Genea and have immune issues.
I am now under the care of a Californian based immunologist called Dr Karen Pace. She has a lot of patients in Australia. Karen orders all of the blood testing through Rosalind Franklin University like Dr Matthias (you MUST get your blood tested in US at RFU). You will need a doctor to provide local prescriptions for medication as obviously Karen can't prescribe for her Australian/international clients. You can check her out online at Conceivable Solutions. I can only speak highly of her as someone who can give you the latest information and help you discover if immune issues are at play. I just wish I found her 6 years ago. She has a great success rate and I am just waiting for some additional treatment before I begin my first stim cycle with her.
Wishing you all the best in whatever approach you take.
