Cysticercosis Antibody, IgG by ELISA (CSF)
Also known as: CYST CSF
Use
This test is used to detect the presence of IgG antibodies to Taenia solium in cerebrospinal fluid (CSF), which may indicate infection with cysticercosis. It is particularly useful when there is clinical suspicion of central nervous system infections such as neurocysticercosis. The test helps to demonstrate the presence of intrathecally-produced specific antibodies. A negative result does not rule out the infection, particularly in low antibody levels or passive transfer from blood.
Special Instructions
Not provided.
Limitations
The interpretation of this test can be complicated by low levels of antibodies in the CSF, passive transfer of antibodies from blood, or contamination through bloody taps. A negative result does not necessarily rule out the infection. It is important to consider these factors when evaluating the test results.
