Cerebrospinal Fluid Testing in Cats

CSF tap in cats:
A guide for new vets

Cerebrospinal fluid (CSF) is vital for diagnosing various neurological conditions in cats, such as infections, meningitis, and cancers within the central nervous system.

In this post we’ve provided an overview of the procedure, testing process, and important considerations when performing a CSF tap.

Procedure overview:

A CSF tap is conducted under anesthesia to keep the cat completely still during the procedure. Depending on the clinical presentation, there are two main methods:

Cisternal Tap: Performed at the base of the neck.
Lumbar Tap: Performed at the base of the tail. A small, guided needle is inserted between the vertebrae to collect a small amount of CSF.

The fluid is then sent to the laboratory for analysis.

Laboratory testing & potential complications

The CSF sample is tested for several key indicators, including:

Cell Types and Protein Levels: Useful for identifying inflammation or infection.
Infectious Agents: Advanced tests, such as PCR, detect specific organisms like Toxoplasma, cryptococcal fungi, or viruses like coronavirus.

Laboratory results are generally available within 24 hours, providing timely information for diagnosis.

Complications are rare. However, they can include:

Spinal Cord Trauma: Possible but uncommon when proper technique is followed.
Brain Herniation: This occurs in sporadic cases with elevated pressure within the brain. To mitigate risk, advanced imaging like MRI may be recommended before proceeding with a spinal tap.

Recovery

Cats typically recover quickly from anesthesia, and any updates regarding the procedure will be communicated promptly.

Appropriate follow-up care will be provided if the cat shows any signs of discomfort or complications.

A CSF tap is a valuable diagnostic tool for evaluating neurological issues in cats.

While complications are rare, safety remains a priority, and advanced imaging may be used to ensure optimal outcomes.
