Autoimmune diseases what is it?

This year 2023 last week of April is Laboratory Week this one week of recognition for those of us who helped the physician in diagnosing their patients disease 99.99% of the time. We are the soldiers behind the scene of aiding diagnosing the patients. In this story I wanted to focus on autoimmune disease. Since this is the most ordered test the physicians ordered in the hospital I work for. Whether it's a blood or spinal fluid.
