An ANA test 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 body’s own tissues — specifically targeting each cell’s nucleus. In most cases, a positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction. But some people have positive ANA tests even when they’re healthy. Your doctor is likely to order an ANA test for a suspected autoimmune disease such as lupus, rheumatoid arthritis or scleroderma.
Requirements: Fasting preferred (Please consult your physician). In order to ensure a quality specimen, we recommend not eating for 2-3 hours prior to your blood draw. If you must eat, try to limit intake of fatty of foods as the fat molecules can accumulate in your blood after a meal and make some lab tests inaccurate.
