Does CSF contain red and white blood cells?

Red blood cell (RBC) count—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. White blood cell (WBC) count—normally very few white blood cells are present.

What cells are in CSF?

The nucleated cells seen in normal adult CSF are predominantly lymphocytes and monocyte/macrophages. A rare neutrophil may be seen. An increased number of lymphocytes, monocytes, or neutrophils in CSF is termed pleocytosis.

What does RBC in CSF mean?

Cell counts: Red blood cells (RBCs) in the CSF mean bleeding. High levels of white blood cells (WBCs) mean meningitis. Tumor cells and abnormal levels of white blood cells mean cancer. Other Results: Antibodies, bacteria, or other organisms in the CSF mean that an infection or disease is present.

Why would CSF be pink?

Xanthochromia is a yellow, orange, or pink discoloration of the CSF, most often caused by the lysis of RBCs resulting in hemoglobin breakdown to oxyhemoglobin, methemoglobin, and bilirubin. Discoloration begins after RBCs have been in spinal fluid for about two hours, and remains for two to four weeks.

What is CSF composed of?

Abstract. Cerebrospinal fluid (CSF) is a clear, colourless ultrafiltrate of plasma with low protein content and few cells. The CSF is mainly produced by the choroid plexus, but also by the ependymal lining cells of the brain’s ventricular system.

Does cerebrospinal fluid have the same composition as blood plasma?

Several constituents are maintained at concentrations different in CSF from those in plasma (Table 32-1), indicating that CSF is not simply a protein-free ultrafiltrate of plasma.

How many red blood cells are in CSF?

Normally, there are no RBCs in the cerebrospinal fluid, and there should be no more than five WBCs per cubic millimeter of CSF.

What does Pink CSF mean?

Pink-red CSF indicates the presence of blood. Blood may originate from a traumatic tap, subarachnoid hemorrhage, intracerebral hemorrhage, or cerebral infarct. It is important to distinguish a traumatic tap from pathologic bleeding.

Should there be RBC in CSF?

Red blood cells (RBCs) should not be present in normal CSF. Typical normal ranges for white blood cells (WBCs) are shown in the table below1,2,3,4,5,6,7,8,9,10. Increased WBCs in the CSF may be indicative of meningitis, malignancy, or demyelinating disease.

What is the Colour of CSF?

Supernatant Color 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.

How does CSF differ from plasma?

The CSF has a composition identical to that of the brain ECF but this is different from plasma. The major differences from plasma are: The pCO2 is higher (50 mmHg) resulting in a lower CSF pH (7.33) The protein content is normally very low (0.2g/l) resulting in a low buffering capacity.
