Lupus erythematosus (LE) cell test measures the presence of a special cell found mostly in patients with systemic lupus erythematosus.
Alternative NamesLupus erythematosus test
How the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThe test is mainly used to diagnose systemic lupus erythematosus (SLE).
Normal ValuesNo presence of LE cells is normal.
What abnormal results meanAbout 50% to 75% of patients with lupus have a positive test. Some patients with rheumatoid arthritis, scleroderma, and drug sensitivities (see drug-induced lupus erythematosus) also have a positive LE cell test.
What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
The LE cell test is only rarely performed because better tests now exist to help diagnose lupus.

What is Leukoesterase?
Leukoesterase = Leukocyte + Esterase. Leukoesterase is a combination word derived from the words Leukocyte and Esterase (LE), which is a urine test for the presence of white blood cells in the urine. "Leukocyte" meaning white blood cell and "Esterase" meaning white blood cell enzyme. Leukoesterase is released by white blood cells. A positive screen for leukoesterase usually indicates a urinary tract infection, in combination with a positive nitrite test - (see "Nitrite Test"). The LE test is also used to screen for gnorrhea and amniotic fluid. In a normal urinalysis Leukesterase is not present or "negative" when listed in lab results. *Please see Leukocyte Esterase Wiki for further discussion and more detailed explantion.
