About this test

The CSF ACE test measures angiotensin-converting enzyme in cerebrospinal fluid, collected by lumbar puncture. It mainly helps evaluate neurosarcoidosis, in which sarcoidosis affects the brain, spinal cord, or nerves.

Normal CSF ACE levels are typically below about 2.5 U/L, varying by lab.

Raised CSF ACE supports a diagnosis of neurosarcoidosis, which may cause facial weakness, headaches, vision problems, seizures, or hormonal disturbances. However, levels can also rise in meningitis, CNS infections, and brain tumors, and a normal result does not rule out the disease.

It is interpreted with MRI and other CSF tests.

Questions about this test

When should I get the ACE LEVEL, CSF test?

A CSF ACE test is advised by a neurologist when neurosarcoidosis is suspected, such as with facial nerve weakness, unexplained headaches, vision changes, seizures, hearing loss, or hormonal problems, especially in people with known sarcoidosis. It is also used to evaluate unexplained brain or spinal cord inflammation on MRI and to monitor treatment.

How should I prepare for the ACE LEVEL, CSF test?

A CSF ACE test requires a lumbar puncture (spinal tap). Inform your doctor about any blood thinners, bleeding disorders, allergies, or pregnancy, and about ACE inhibitor medicines or steroids, as these can affect results. Fasting is usually not required. Empty your bladder beforehand, and plan to rest after the procedure.

Do I require fasting for the ACE LEVEL, CSF test?

No, fasting is usually not required for a CSF ACE test. You can eat and drink normally unless your doctor advises otherwise, for example if sedation is planned for the lumbar puncture. Inform your doctor about any blood thinners or bleeding disorders, and follow the hospital’s specific instructions.
