## Overview

[edit | edit source]

There are no specific laboratory findings associated with cryptococcal infection, but it can be diagnosed through culture, CSF microscopy, or by cryptococcal antigen (CrAg) detection.

## Laboratory Findings

[edit | edit source]

There are no specific laboratory findings associated with cryptococcal infection, but it can be diagnosed through:[1][2][3]

1. Culture
2. CSF microscopy
3. Cryptococcal antigen (CrAg) detection

* In patients with HIV-related cryptococcal meningitis, 55% of blood cultures and 95% of CSF cultures are positive and visible colonies can be detected within 7 days.
* The opening pressure in the CSF may be elevated, with pressures ≥25 cm H2O in 60% to 80% of patients.
