Cerebrospinal Fluid Deoxyinosine Concentration
This test measures the amount of deoxyinosine, a breakdown product of nucleic acids, in your cerebrospinal fluid (CSF). It may be used to assess certain metabolic or genetic conditions affecting the brain or spinal cord.
["This test helps evaluate conditions linked to abnormal nucleic acid metabolism in the nervous system."]

Why Might This Test Be Ordered?
Your healthcare provider may recommend this test if you have symptoms or a history suggestive of conditions like mitochondrial disorders, lysosomal storage diseases, or other metabolic syndromes that affect how your body breaks down genetic material. It could also be part of a broader evaluation for neurological symptoms, especially when other tests are inconclusive.
What Does the Test Involve?
A small amount of cerebrospinal fluid is collected through a procedure called a lumbar puncture (spinal tap). The fluid is then sent to the lab for analysis. This test is typically done under sterile conditions to ensure accuracy.
Sample Collection and Preparation
The procedure for collecting CSF involves inserting a needle into your lower back to draw fluid from the spinal canal. You may feel pressure or mild discomfort, but the procedure is usually quick and well-tolerated. You’ll lie on your side with your knees bent, and the area is numbed with a local anesthetic.
What to Expect After the Test
After the procedure, you may experience mild soreness or headache, which can be managed with rest and over-the-counter pain relievers. You’ll need to stay hydrated and avoid strenuous activity for a short time. Your healthcare provider will give specific instructions based on your situation.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated levels of deoxyinosine in CSF can be associated with certain inherited metabolic disorders, such as mitochondrial diseases or lysosomal storage disorders, which affect how cells process energy and genetic material. While this test is not routinely performed, it may be critical in diagnosing specific conditions when symptoms or genetic testing suggest a metabolic basis for neurological issues.
