Abnormal Quan-DSDNA Results: Implications for Pregnancy - Obstetrics and Gynecology

Abnormal DS DNA Test Results


I recently went to the gynecologist for a government-subsidized preconception check-up along with some out-of-pocket tests.
The results showed only one abnormality: a Quan-DSDNA level of 294.535 (reference range: <200 (-), (+/-) 201~300, (+) >301).
All other tests, including urine protein, thyroid function, and other blood tests, were normal, and there were no symptoms of systemic lupus erythematosus (SLE) (since Google shows SLE when searching for dsDNA).
When reviewing the report, the doctor only mentioned the antibody abnormality and advised that if I experience recurrent miscarriages in the future, I may need to take aspirin or antimalarial medications.
Does this abnormal index indicate the presence of lupus, or could it be related to other conditions?

The abnormal result of your Quan-DSDNA test, with a value of 294.535 IU/ml, indicates the presence of anti-dsDNA antibodies, which are often associated with autoimmune conditions, particularly systemic lupus erythematosus (SLE). However, it is important to note that the presence of these antibodies alone does not confirm a diagnosis of lupus or any other autoimmune disease. The interpretation of this result should be done in conjunction with clinical symptoms, medical history, and other laboratory findings.

In the context of pregnancy, the presence of anti-dsDNA antibodies can have implications, particularly if you have a history of recurrent miscarriages or other pregnancy complications. These antibodies are known to be associated with an increased risk of pregnancy complications, including miscarriage, preterm birth, and the development of conditions such as preeclampsia. Therefore, if you have experienced multiple miscarriages, your healthcare provider may recommend low-dose aspirin or hydroxychloroquine (an anti-malarial medication that has immunomodulatory effects) to help manage these risks during pregnancy.

It's also crucial to understand that not all individuals with elevated anti-dsDNA antibodies will develop lupus or experience complications in pregnancy. Some individuals may have these antibodies without any clinical manifestations of an autoimmune disease, a condition referred to as "seropositive without disease." This means that while the antibodies are present, they may not be causing any significant health issues.

In your case, since you mentioned that you do not have any symptoms of lupus and other tests (such as urine protein, thyroid function, and other blood tests) are normal, it is possible that the elevated anti-dsDNA is an isolated finding. However, it is essential to maintain regular follow-ups with your healthcare provider, who may monitor your antibody levels and overall health as you consider pregnancy.

If you are planning to conceive, it would be wise to have a thorough discussion with your healthcare provider about the implications of your test results and any necessary precautions or treatments that may be beneficial for a healthy pregnancy. They may also consider referring you to a specialist in maternal-fetal medicine or a rheumatologist who can provide further insights into managing your health in relation to pregnancy.

In summary, while an abnormal Quan-DSDNA result can be concerning, it does not automatically indicate a diagnosis of lupus or other autoimmune diseases. The clinical context, including your overall health and any symptoms you may have, is crucial in determining the significance of this finding. Regular monitoring and appropriate management can help mitigate potential risks during pregnancy, ensuring the best possible outcomes for both you and your future child.
