Lipopolysaccharide (LPS) Antibody Screening in Serum/Plasma by Immunoassay
This test measures antibodies that your immune system produces in response to bacterial lipopolysaccharides (LPS), which can be found in certain bacteria. It helps identify if your body has detected and reacted to these substances.

What Does This Test Measure?
Lipopolysaccharides (LPS) are complex molecules found on the surface of certain bacteria. When your immune system encounters these molecules, it can produce antibodies specific to them. This test detects the presence of these antibodies in your blood, which can indicate an immune response to bacterial exposure.
Why Might You Need This Test?
Doctors may order this test if you have symptoms suggestive of an immune response to bacterial infection, such as persistent inflammation, unexplained fevers, or conditions like sepsis, autoimmune diseases, or chronic infections. It can also be used in research or clinical studies involving immune monitoring.
What to Expect Before the Test
No special preparation is usually needed for this test. You may have a small needle inserted into a vein in your arm to draw a blood sample. If you are on blood-thinning medication or have a history of bleeding disorders, let your healthcare provider know before the test.
What to Expect During the Test
The blood sample will be collected in a tube and sent to a lab for analysis. The immunoassay method detects antibodies against LPS, which are then measured to determine the presence and level of these antibodies.
