Autoimmune Disorder Of The Soul Can Blood Tests For An Autoimmune Disorder Come Back As A False Positive?

Can blood tests for an autoimmune disorder come back as a false positive? - autoimmune disorder of the soul

I went to the doctor and was told last week he tested positive for an autoimmune disease. not sure what, but it will be sent to a specialist to find out. I want to know is if it could be otherwise than false positive. would have been happening in my body, or the tests are always correct. If anyone out there that you can make. Thank you, and I thank you now.
