LE cell test

Alternative names:

lupus erythematosus test

Normal values:

No presence of LE cells is normal.

What abnormal results mean:

The LE cell test is used primarily to diagnose systemic lupus erythematosus (SLE). 70 to 80% of patients with SLE have a positive test. These patients have antibodies against the constituents of the nuclei within their own cells. Some patients with rheumatoid arthritis, scleroderma, and drug sensitivities (see drug-induced lupus erythematosus) also exhibit a positive LE cell test.
