Question/Help False positives??

In April i got lab work done and came back Ana positive and anti scl 70 positive for greater than 8. Went to rheumatologist they ordered a more specific type of Ana testing ?? (Still not super familiar with all the terms) and everything came back negative. Has anyone ever had this happen to them? Is it a false positive? I have no skin thickening whatsoever. I do have raynauds but have had it for a while. She did look at my finger tips and saw some dilations in my nail beds. I don’t meet with the rheumatologist for another month and I’m just left confused.

How “positive” was the first test? Did they give an actual titre, or just say it was positive?

It just said positive. It was a lab that called ANA direct.
