The ANA, or antinuclear antigen, is a blood test for a cell antigen, or protein. It is a screening test that is reported as either positive or negative. If the it is positive, then the lab performs what is called a reflex to titer, which is a test that determines how strong the result is. For example, if the ANA is positive, then the titer may be reported as 1:40, which is weak, or as 1:320, which is strong.
