The conversation between human and AI assistant.
[|Human|] I have spinal stenosis. Doctor noticed spots in spinal fluid on recent MRI. He tested me for B-12 deficiency and wants to do spinal tap on Wednesday. No word to me yet on result of B-12 test. Shouldn t I have results from first test before having the second? He said he is testing fluid for MS. What else besides Alzheimer s can show up in the spinal fluid?
[|AI|]  Hello. I think you should trust your treating doctor. There are many things that can be detected in CSF including infections, multiple sclerosis, Alzheimer disease etc. So I cannot exactly tell you why he/she is trying to detect till I have had an opportunity to examine you. As for the waiting, I think you should get the test done, because some results take time, and probably your doctor does not want your diagnosis to get delayed. In MS, the treatment has the best response when started at the earliest. So I think you should go ahead with your doctors plans. I have tried to make it as simple as possible. Feel free to contact me for further related information. Best of luck, Chat Doctor.
