Use

This test is used to quantitatively measure the levels of immunoglobulins in cerebrospinal fluid (CSF). Quantification of immunoglobulins in CSF is useful for diagnosing and monitoring neurological diseases, such as multiple sclerosis, where an abnormal immune response involves the central nervous system. Elevated immunoglobulin levels in CSF can indicate a breach of the blood-brain barrier or intrathecal synthesis of immunoglobulins, which are often associated with inflammatory conditions.
