Cytoplasmic positive alone is ANA positive or negative? Hello, I would appreciate if you can share with me how to report cytoplasmic staining (without nuclear staining) as ANA positive or negative?

Ro/SS-A and La/SS-B negative in HEp-2 IFA. Can I get positive Ro and La with negative ANA IFA? How to explain if yes?

ANA titer reporting. We would also like recommendations on the report of ANA results. For example, when report such as 1:80 dilution AC-1 homogeneous 4+ are made, is it correct to report in crosses (e.g. +++) or only the dilution and the pattern?
Fine Art with AC-29. Is it critical that all five elements of the subcellular domains associated with the AC-29 pattern be evaluated in order to correctly classify an individual serum as AC-29? In other words, can it be classified as AC-29 with staining of only some of the five elements?
