Lab test
Lupus Panel
Lupus Panel is a laboratory test you can request directly. A Lupus Panel is a group of tests used to help diagnose and monitor autoimmune conditions, particularly lupus.
What this test is
This panel includes several blood tests that look for specific antibodies and proteins in your body. These components can indicate the presence of an autoimmune disease where the body's immune system mistakenly attacks its own tissues.
What it measures
- Antinuclear Antibodies (ANA) — antibodies that target the cell's nucleus
- Anti-dsDNA Antibodies — antibodies against double-stranded DNA
- Anti-Sm Antibodies — antibodies against the Smith antigen
- Complement C3 — a protein involved in the immune system
- Complement C4 — another protein involved in the immune system
- Anti-Ro/SSA Antibodies — antibodies against Ro/SSA antigens
- Anti-La/SSB Antibodies — antibodies against La/SSB antigens
What the test involves
This test requires a blood sample, which is typically collected through a standard venipuncture procedure. A healthcare professional will draw blood from a vein in your arm.
Why it is often ordered
Clinicians often order a Lupus Panel when a patient presents with symptoms suggestive of lupus or other connective tissue diseases. It can help differentiate lupus from other conditions and assess disease activity.
