There is no one test that can diagnose Lupus! Doctors must take your entire medical history, do an analysis of the results obtained in routine laboratory tests and run some specialized tests related to immune status.
Routine clinical tests which can indicate that you may have active Lupus includes:
* sedimentation rate (ESR) and CRP (C-reactive protein) binding, both of which are frequently elevated in inflammation from any cause
serum protein electrophoresis which may reveal increased gammaglobulin and decreased albumin
* routine blood counts which may reveal anemia and low platelet and white cell counts
* routine chemistry panels which may reveal kidney involvement by increases in serum blood urea nitrogen and creatinine abnormalities of liver function tests
* increased muscle enzymes (such as CPK) if muscle involvement is present.
* Anti-nuclear antibody test (ANA) to determine if autoantibodies to cell nuclei are present in the blood
* Anti-DNA antibody test to determine if there are antibodies to the genetic material in the cell
* Anti-Sm antibody test to determine if there are antibodies to Sm, which is a ribonucleoprotein found in the cell nucleus
* Serum (blood) complement test to examine the total level of a group of proteins which can be consumed in immune reactions
* Complement proteins C3 and C4 test to examine specific levels of these proteins.
