If you have CSF leak symptoms specific to your nose or face (especially a runny nose), your provider will likely want to test that fluid. The most likely lab test to help is a beta-2 transferrin test.

Testing fluid from the ear or nose for β-2 transferrin is the recommended method to assess patients for a cranial CSF leak because this approach is noninvasive as well as highly sensitive and specific.

2023年11月21日 · This test can show exactly where a CSF leak is, and help to determine the most appropriate treatment plan. High-resolution CT provides images in even greater detail and also may be used.

Glucose oxidized test: The CSF glucose from nasal or ear secretions has long been a classical method in testing CSF leak. In general, the glucose oxidase strips show positive result when the sample has a concentration over 20 mg/dL.

2023年11月21日 · There are two distinct types of CSF leaks: spinal CSF leaks and cranial CSF leaks. Each type has different symptoms, causes and treatments. A spinal CSF leak occurs anywhere in the spinal column. The most common symptom of a spinal CSF leak is a headache.

Cerebrospinal fluid (CSF) is a clear liquid that surrounds the brain and spinal cord. It provides a cushion for delicate brain and spinal tissue. Reduced cerebrospinal fluid, as in the case of a leak, requires immediate care by a trained expert.

Myelography is the gold-standard test for localizing the site of spinal leak. Left: Advanced hyperdynamic CT myelogram performed to identify the site of CSF leak associated with a bone spur (arrow). Right: MR myelogram with intrathecal …

What is a cerebrospinal fluid (CSF) analysis? A cerebrospinal fluid (CSF) analysis tests a sample of your CSF for diseases that affect the brain and spinal cord, which make up your central nervous system. Your central nervous system controls and coordinates everything you do, including your ability to move, breathe, see, think, and more.

2025年3月11日 · Any sample of discharge that contains CSF can indicate a leak. If a doctor suspects a CSF leak, they may order a CT or MRI scan to help confirm the diagnosis and locate the leak. Treatment...

In this test, a small amount of watery discharge from the nose or ear is collected and tested in a lab. A positive result indicates a CSF leak. A specific type of MRI called a CISS (constructive interference in steady state) sequence MRI may be performed.
