EMERGENCY CALL 
Description:
The Cryptococcal Antigen (CrAg) CSF/Serum Test is a rapid diagnostic test used to detect Cryptococcus infection, particularly in HIV/AIDS patients at risk for cryptococcal meningitis. The test identifies Cryptococcal antigen (CrAg) in cerebrospinal fluid (CSF) or serum, helping in early diagnosis and treatment.
Key Points:
Detects Cryptococcal antigen in CSF or serum, indicating an active Cryptococcus infection.
Used primarily for screening in HIV patients with low CD4 counts and diagnosing cryptococcal meningitis.
A positive result in CSF confirms cryptococcal meningitis, requiring urgent antifungal treatment.
A positive result in serum suggests an early or disseminated infection.
The test is highly sensitive and specific, providing results within 10–15 minutes.
Importance: Early detection of cryptococcal infection through the CrAg test can significantly reduce mortality, especially in immunocompromised individuals.
