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.

If the test is positive, a panel of tests may be done to identify specific antibodies. 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.
