I'm really sympathetic because my bone marrow and fat pad biopsies are scheduled in 10 days, and not knowing what's going on is stressful. But I haven't read up on bone marrow biopsies and haven't had mine yet, and don't know enough to try to respond.
Can you contact your doctor with a list of questions via an online Portal, perhaps? I'm learning that some doctors are very thoughtful and responsive in that mode (hooray!) and thus we can minimize our wait time before hearing test result interpretations. You might be able to ask for a call back rather than a written response, if you prefer. Best of luck!
