Antinuclear antibody is positive in 1 out of every 9 females.
ANA is reported in tiers that are reported in numbers that double (1:40, 1:80, 1:160, 1:320,...etc).

However, antinuclear antibodies (ANA) do NOT correlate with disease activity or symptoms severity.

In this video, we will talk about quick hints on Osteoarthritis, Rheumatoid Arthritis, Systemic lupus erythromatosis (SLE), scleroderma, sjögren syndrome, and others.
