Introduction

Serum cryptococcal antigen tests are critical diagnostic tools for the detection of Cryptococcus neoformans infection, particularly in immunocompromised patients. The sensitivity of these tests is paramount to ensuring early detection and treatment.

Cryptococcal Disease Overview

Cryptococcal disease is a severe fungal infection primarily affecting individuals with weakened immune systems, such as those with HIV. The infection can lead to meningitis if not diagnosed and treated promptly.

Serum Cryptococcal Antigen Tests

These tests detect the presence of cryptococcal antigens in the blood. They are preferred due to their non-invasive nature and quick turnaround time compared to traditional culture methods.

Sensitivity Analysis

Sensitivity is a measure of a test's ability to correctly identify those with the disease (true positive rate). High sensitivity is crucial for early diagnosis and treatment initiation. The sensitivity of serum cryptococcal antigen tests typically ranges from 93% to 100%, depending on the test parameters and patient population.

• Sensitivity in patients with HIV: Approximately 95%-100%
• Sensitivity in non-HIV patients: Approximately 93%-98%
• Factors influencing sensitivity include the stage of infection and sample quality.
