Question

Quizplus · Accepted Answer

The antinuclear antibody (ANA) test is used to identify antibodies that attack the nucleus of the individual's own body cells, indicating the presence of an autoimmune disease. An autoimmune disease occurs when the immune system mistakenly attacks the body's own tissues, and the ANA test helps to diagnose diseases such as lupus, rheumatoid arthritis, and scleroderma. The other options listed (bone marrow, blood typing, complete blood count, and blood culture) do not relate to the identification of antibodies that attack the nucleus of the individual's own body cells.
