Lupus antibodies

At IntroLab in Belgrade, we specialize in performing various medical tests, including analysis for lupus antibodies. The reliability of our results, based on expertise and commitment to precision, is crucial in diagnosing and monitoring autoimmune diseases like lupus.

What are Lupus antibodies?

Lupus antibodies are specific antibodies produced by the immune system when it mistakenly attacks its own tissue, identifying it as foreign. These antibodies are characteristic of autoimmune diseases, particularly systemic lupus erythematosus (SLE). The analysis for lupus antibodies is a test that detects the presence of these antibodies in the blood.

When is this test necessary?

The test for lupus antibodies is most often conducted when a doctor suspects lupus based on the patient’s symptoms, such as:

• Fatigue
• Fever
• Joint pain
• Rash
• Sensitivity to sunlight

The test may also be recommended if other test results, such as blood or urine analyses, have shown abnormalities consistent with lupus. Lupus antibodies can also be periodically checked during lupus treatment to monitor the response to therapy.

How are the results interpreted?

The results of the lupus antibody test are interpreted in the context of the patient’s symptoms and medical history. Lupus antibodies in the blood may indicate lupus, but people without lupus can have these antibodies. Also, some patients with lupus may have a negative lupus antibody test. Interpreting the results requires expertise and clinical insight, so it is important to discuss the results with your doctor.

Specifics and subtypes of analysis

There are various subtypes of lupus antibodies, including:

• Antinuclear antibodies (ANA)
• Antibodies to double-stranded DNA (dsDNA)
• Antiphospholipid antibodies

These specific antibodies are often tested together, as they can provide more detailed information about the type and activity of lupus. These analyses have specifics and may require additional steps or different sample preparation methods.
