Although there is no all-inclusive blood test for lupus, several tests can help physicians to diagnose lupus, measure disease activity, and assess a patient’s response to certain medications.
- Lupus Blood Tests Several blood tests can be performed to detect specific auto-antibodies and help make the diagnosis of lupus. These blood tests are not conclusive by themselves, but combining the tests with certain physical findings can help to corroborate a diagnosis.
- Antiphospholipid Antibodies Approximately 50% of people with lupus possesses antiphospholipid antibodies, which are antibodies directed against phosphorus-fat components of your cell membranes called phospholipids, certain blood proteins that bind with phospholipids, and the complexes formed when proteins and phospholipids bind.
- Screening Laboratory Tests The following tests provide the starting point of any medical workup. By comparing your test results to the normal values for your age, sex, and personal circumstances (i.e., medications you may be taking, health conditions you might have, etc.), your doctor can monitor changes in your disease activity and overall health.
- Other Clinical Tests These tests allow your physicians to monitor changes in lupus activity and the effectiveness of your medications.
