How many have a positive ANA?

I dont but its very Common to get a autoimmune-like reaction from chronic pathogens.

There is a Youtuber that has sadly passend away: Bartonella Babe is her Name.

She once Interviewed a Young man with high positive Auto antibiodies aswell as tnf-alpha wich resolved after intensive Treatment with rifabutin for bartonella.

So that is possible

I have in the past. It’s very common for this antibody to go from positive negative throughout the year. It can change a lot other antibodies generally are not like that.

ANA is kind of the “master”auto immune antibody. It does not always mean lupus.

I have other known auto immune issues which can be related to positive ANA values. Even Hashimoto thyroid, which has its own antibodies can trigger a ANA positive.

Usually, if you have positive ANA, any a doctor that knows about it will do the second level testing for it checking the titter. It’s from those results Which are sometimes used in lupus diagnosis
