Description
Why It’s Done:
This test is primarily done to:
• Diagnose cryptococcal meningitis, particularly in HIV-positive or immunocompromised individuals.
• Detect systemic cryptococcosis, which may affect the lungs, blood, or other organs.
• Screen high-risk patients, such as those with advanced HIV/AIDS, for asymptomatic infection before it becomes severe.
• Monitor response to treatment in known cryptococcal infections.
Symptoms leading to testing may include:
• Headache
• Fever
• Neck stiffness
• Confusion or disorientation
• Blurred vision
• Seizures (in CNS involvement)
• Respiratory symptoms (if lung involvement is suspected)
Preparation:
• No special preparation is usually needed.
• If CSF is required, it will be collected by a lumbar puncture; you may need to lie flat afterward to reduce the risk of headache.
• For blood tests, a routine blood draw is performed; no fasting is necessary.
• Inform your doctor of any current medications, especially antifungals or immunosuppressants.
• Follow any specific instructions provided by your healthcare provider.
