How much anti-double-stranded DNA is considered positive?

Under normal circumstances, anti-double-stranded DNA (anti-dsDNA) is an antibody used to detect autoimmune diseases such as systemic lupus erythematosus (SLE). An anti-dsDNA level of 100 IU/ml or higher is generally considered positive. If you experience any discomfort, it is recommended to seek medical attention promptly. The details are as follows:

When the concentration of anti-double-stranded DNA antibodies reaches or exceeds 100 IU/ml, it indicates that elevated levels of these antibodies have been detected in the blood sample, and the result is considered positive. However, it is important to note that a positive result does not necessarily mean the individual has systemic lupus erythematosus or another autoimmune disease. A positive anti-dsDNA result should be evaluated in conjunction with other clinical information, such as symptoms including fatigue, joint pain, rashes, and fever. Doctors may also test for other autoantibodies, such as antinuclear antibodies (ANA) and anti-phospholipid antibodies. The presence of these antibodies is associated with autoimmune conditions like systemic lupus erythematosus.

In daily life, it is advisable to reduce consumption of spicy and stimulating foods, and instead consume more light, easily digestible foods such as egg custard, rice porridge, and Chinese yam porridge, which are beneficial for overall health.
