A positive ANA: -detects antinuclear antibodies (ANA) in your blood. Your immune system normally makes antibodies to help you fight infection. In contrast, antinuclear antibodies often attack your tissues — specifically targeting a cell's nucleus.
In most cases, indicates that your immune system has launched a misdirected attack on your own tissue. However, a negative ANA does not rule out any condition.
