Thank you so much for your words of understanding and support. We received the diagnosis on Monday, I allowed myself to cry on Tuesday, then I started taking action on Wednesday. Feels better to be proactive than reactive for sure. Like you, we kept thinking there has to be a mistake. But having accepted the diagnosis, I'm now looking for 'centers of excellence' that will review all of my sons tests (and do more as needed) to get a complete picture of his diagnosis, long term prognosis, suggested treatment options, and a realistic plan for how a 20 year old very active male (skateboarding, snowboarding, car racing) can enjoy a balanced life. I'm afraid if too restrictive, he will not follow the plan completely and the result could be bad. I see that some of the big university research centers/hospitals have a special focus on Lupus Anticoagulant Syndrome and hope to find a good good program and have him evaluated soon. Again, thank you for response, very much appreciated!
