I’ve had tests done where false negatives ran 20+% this is well known. I had every single symptom of the condition. Test came back negative. Doctor declared no issue, no reason to continue care. A better doctor confirmed the diagnosis with additional tests. Growing belief that a false negative may mean a worse variation of the disease. Episode cost me an added year of organ damage.
