Casandra Test Code LC36045Version 1 (DRAFT)
Performing Lab
ANA by IFA, Reflex to Titer and Pattern
Also known as: ANA, IFA, ANA-Hep2
Clinical Use
Order TestUse
Detect antibodies to nuclear antigens
Special Instructions
Not provided.
Limitations
Fifty percent of individuals over 80 years have low titer ANA, possibly confounding results. Medications can induce lupoid conditions. The titer can decrease after stopping medication. The presence of antibodies can interfere with detection, and low titers might merely suggest rheumatoid arthritis or other conditions without significant disease.
