Cerebrospinal Fluid (CSF) Analysis

Spinal fluid

Biomarkers included in this panel:

Appear CSF

Spinal fluid

Cerebrospinal fluid (CSF) is a clear, watery liquid that flows around the brain and spinal cord, surrounding and protecting them. CSF testing is performed to evaluate the level or concentration of different substances and cells in CSF in order to dia

CSF Glucose

Spinal fluid

CSF glucose, also known as cerebrospinal fluid glucose or glycorrhachia, is a measurement used to determine the concentration of glucose in cerebrospinal fluid. The normal reference range for CSF glucose is typically between 50-80 mg/dL. If the le

CSF RBC

Spinal fluid

Normally no red blood cells are present in the CSF. The presence of red blood cells may indicate bleeding into the CSF or may indicate a “traumatic tap” – blood that leaked into the CSF sample during collection.

CSF Total Protein

Spinal fluid

Protein appears in nearly all body tissues, along with your enzymes, blood, and cerebrospinal fluid (CSF). Healthy CSF has a low amount of protein.‌ - Protein level, opening pressure, and CSF-to-serum glucose ratio vary with age. - CSF pro

CSF WBC

Spinal fluid

Normally very few white blood cells are present in CSF. A significant increase in white blood cells in the CSF can be caused by infection or inflammation of the central nervous system.

Lymphs, CSF

Spinal fluid

Lymphocytes (Lymphs) in cerebrospinal fluid (CSF) are an important marker often assessed during lab tests to evaluate the health of the central nervous system. Lymphocytes are a type of white blood cell that plays a critical role in the immune respon

Oligoclonal Bands (IgG), CSF

Serum Spinal fluid

Oligoclonal bands (OCBs) are special types of proteins (called immunoglobulin G or IgG) that show up in cerebrospinal fluid (CSF), the fluid that surrounds your brain and spinal cord. These bands form when the immune system produces antibodies in the

Segmented Neutrophils, CSF

Spinal fluid

Segmented Neutrophils (CSF) refer to mature white blood cells found in the cerebrospinal fluid (CSF), which play a key role in the body’s immune response. Normally, neutrophils are present in low or undetectable levels in the CSF. Elevated leve

Supernatant CSF

Spinal fluid

Normal CSF is crystal clear. However, as few as 200 white blood cells (WBCs) per mm3 or 400 red blood cells (RBCs) per mm3 will cause CSF to appear turbid (=cloudy). Xanthochromia is a yellow, orange, or pink discoloration of the CSF, most often c
