Lupus Blood Test Panel
There is no single test that can definitively diagnose lupus, an autoimmune disease that can affect various parts of the body, including the skin, joints, and organs. However, there are several blood tests that can be performed as part of a lupus blood test panel to help support or rule out a diagnosis of lupus.
Some of the common blood tests included in a lupus panel are:
Antinuclear Antibody (ANA) Test: This test measures the presence and amount of antibodies that target the nucleus of cells. ANA is present in the majority of individuals with lupus.
Anti-double-stranded DNA (anti-dsDNA) Test: This test measures the presence of antibodies that attack the DNA in the body. High levels of anti-dsDNA antibodies are highly specific for lupus.
Anti-Smith (anti-Sm) Antibody Test: This test measures the presence of antibodies against a specific protein called Sm, which is found in the nucleus of cells. Anti-Sm antibodies are highly specific for lupus.
Complete Blood Count (CBC): This test measures the number of different types of blood cells in the body. Abnormalities in blood cell counts can be a sign of lupus.
Complement Level Test: This test measures the level of complement proteins in the blood. Low levels of complement proteins are often found in individuals with lupus.
Erythrocyte Sedimentation Rate (ESR) Test: This test measures the rate at which red blood cells settle in a tube. Elevated ESR levels can indicate inflammation in the body, which is common in lupus.
C-reactive Protein (CRP) Test: This test measures the level of a protein called CRP, which is produced by the liver in response to inflammation. Elevated CRP levels can indicate inflammation in the body.
The results of a lupus blood test panel should be interpreted in conjunction with other clinical and laboratory findings to make a definitive diagnosis of lupus. A healthcare provider experienced in diagnosing and treating autoimmune diseases should be consulted for proper diagnosis and management.
