The indicators of lupus erythematosus examination are roughly divided into 4 aspects, namely antinuclear antibody test, immunological test, routine blood test and urine test. Among them, immunological tests include anti-double-stranded DNA antibody and antiphospholipid antibody test, which are an important indicator for the diagnosis of lupus erythematosus. Routine blood test, if one or more abnormalities are found, can be used as a diagnostic indicator of hematologic damage in lupus erythematosus. Urine test is highly suspected of lupus erythematosus kidney damage if there are urine protein or red blood cell indicators in the urine night. The test results should also be combined with the clinic to confirm the diagnosis.
