Antinuclear antibody panel

ANA; ANA panel; ANA reflexive panel; SLE - ANA; Systemic lupus erythematosus - ANA

The antinuclear antibody panel is a blood test that looks at antinuclear antibodies (ANA).

ANA are antibodies produced by the immune system that bind to the body's own tissues. The antinuclear antibody test looks for antibodies that bind to a part of the cell called the nucleus. The screening test determines whether such antibodies are present. The test also measures the level, called the titer, and the pattern, which can be helpful. If the test is positive, a panel of tests may be done to identify specific antigen targets. This is the ANA antibody panel.

Blood test

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
