Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample taken from an arm vein.
Test Time:
The test findings are typically accessible in a few days.
Test Normal Range:
The test results are reported as positive or negative, indicating the presence or absence of anti ds DNA antibodies.
What is the Test?
The Anti ds DNA test detects the presence of antibodies against double-stranded DNA (ds DNA) in the blood. These antibodies are commonly found in individuals with autoimmune conditions like systemic lupus erythematosus (SLE).
Test Procedure:
A healthcare professional will clean the area around a vein in your arm. A needle is inserted into the vein, and a blood sample is collected into a vial or syringe. The blood sample is sent to a laboratory for analysis. Laboratory technicians perform tests to detect anti ds DNA antibodies.
When to Take the Test:
The Anti ds DNA test is ordered when an individual has symptoms suggestive of autoimmune disorders like SLE. These symptoms may include joint pain, skin rashes, fatigue, and fever.
Who Should Take This Test:
People suspected of having autoimmune disorders, particularly systemic lupus erythematosus, may be advised to take the Anti ds DNA test by their healthcare provider.
Precautions for Exceptional Cases (Pregnancy etc.):
If you are pregnant, breastfeeding, or have any existing medical conditions, inform your healthcare provider before taking this test. Pregnancy can sometimes affect the Anti ds DNA test results.
FAQs:
Q1: Are positive Anti ds DNA results definitive for diagnosing lupus?
A: Positive results indicate the presence of anti ds DNA antibodies but are not solely diagnostic for lupus. They are considered along with other clinical and lab findings for diagnosis.
Q2: Can other conditions cause positive Anti ds DNA results?
A: While Anti ds DNA antibodies are strongly associated with lupus, they can also be found in other autoimmune and non-autoimmune conditions.
Q3: Can Anti ds DNA levels fluctuate over time?
A: Yes, Anti ds DNA levels can vary, and monitoring their changes may help in disease management and treatment decisions.
Q4: Are there any risks associated with the blood test?
A: The test involves a needle prick, which carries minimal risk. Some people might experience mild bruising or discomfort at the puncture site.
Q5: Can a negative result rule out lupus?
A: A negative result does not necessarily rule out lupus, as not all lupus patients have detectable anti ds DNA antibodies. A comprehensive assessment is needed for diagnosis.
