抗核抗體 Anti-Nuclear Antibody (ANA)
Antinuclear Antibody (ANA)

*Antinuclear antibodies (ANA) are a group of autoantibodies that target components within the cell nucleus. They are commonly used to screen for autoimmune diseases, such as systemic lupus erythematosus (SLE), scleroderma, and others.

*Normal Range
Negative: No autoimmune response detected, indicating the absence of significant autoimmune disease.
Positive: A positive result may indicate the presence of an autoimmune disease but can also be found in healthy individuals.

*Significance of a Positive ANA
-Autoimmune Diseases:
A positive ANA is commonly associated with autoimmune diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis, and Sjögren's syndrome.
-Further Testing:
A positive ANA result requires additional testing to identify specific antibodies (e.g., Anti-dsDNA, Anti-SSA antibodies) to confirm the exact cause and diagnose the disease.

*Health Recommendations
-Further Examination:
If ANA is positive, further detailed testing is necessary to confirm the presence of an autoimmune disease.
-Early Diagnosis and Treatment:
Early diagnosis and treatment of autoimmune diseases can effectively slow disease progression and improve long-term outcomes.

*Conclusion
ANA is a valuable marker for detecting autoimmune diseases. A positive result requires further confirmation through additional tests. Early detection and treatment of autoimmune diseases help minimize organ damage and improve quality of life.
