Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
Cerebrospinal fluid (CSF) sample is required for this test. This fluid is obtained through a lumbar puncture (spinal tap), where a needle is inserted into the spinal canal in the lower back to collect CSF.
Test Time:
The test typically takes a short amount of time to collect the CSF sample, usually about 30 minutes to an hour. Results are usually available within a few days after the sample reaches the laboratory.
Test Normal Range:
The normal range for this test is typically “negative,” meaning that Cryptococcus antigen is not detected in the CSF. The presence of Cryptococcus antigen in the CSF may indicate a fungal infection, such as cryptococcal meningitis.
What is the Test?
The Cryptococcus antigen test for cerebrospinal fluid is used to detect the presence of Cryptococcus neoformans antigens in the CSF. Cryptococcus neoformans is a fungus that can cause serious infections, particularly in individuals with weakened immune systems, such as those with HIV/AIDS.
Test Procedure:
To perform the Cryptococcus antigen test for CSF: A healthcare provider will perform a lumbar puncture to collect a CSF sample. The CSF sample is then sent to a laboratory. In the laboratory, the CSF is tested for the presence of Cryptococcus neoformans antigens using specific antibodies.
When to Take the Test:
This test is taken when a healthcare provider suspects a central nervous system infection, particularly Cryptococcus meningitis. It is also used for monitoring the progress of treatment for this infection.
Who Should Take This Test:
Individuals with symptoms and risk factors for Cryptococcus infection, especially those with weakened immune systems, such as HIV/AIDS patients. Those with known or suspected central nervous system infections.
