Lateral Flow Assays

The sōna Aspergillus Galactomannan LFA is a rapid, qualitative diagnostic test used to detect Aspergillus galactomannan antigens in serum and bronchoalveolar lavage (BAL) fluid. It aids in the early detection of invasive aspergillosis, a serious fungal infection primarily affecting immunocompromised patients, including those with hematologic malignancies or transplant recipients.

Key Features:

• Sample types: Serum and BAL fluid
• Turnaround time: ~30 minutes
• Visual or reader-based result interpretation
• Index value threshold for positivity: ≥ 0.50
• No cross-reactivity with other fungi like Candida or Cryptococcus

This assay is particularly valuable due to its ease of use, speed, and suitability for resource-limited settings, enabling earlier initiation of antifungal treatment.

The CrAg® Lateral Flow Assay is IMMY’s flagship product for the detection of cryptococcal antigen (CrAg) in serum, plasma, cerebrospinal fluid (CSF), or whole blood. It is used for diagnosing cryptococcosis, particularly cryptococcal meningitis, a severe infection common in HIV/AIDS patients.

Key Features:

• High sensitivity and specificity (>99%)
• Sample types: CSF, serum, plasma, whole blood
• Turnaround time: ~10 minutes
• Room temperature storage (no refrigeration needed)
• WHO-prequalified and used globally, especially in resource-constrained areas

The CrAg® LFA has revolutionized the management of cryptococcal disease by providing fast, accurate results without the need for laboratory infrastructure, contributing significantly to reducing mortality in high-risk populations.
