A Viral Transport Medium (VTM) is a specialized liquid solution used to preserve and transport viral specimens (such as nasopharyngeal or oropharyngeal swabs) for laboratory testing. It maintains the viability and stability of viruses during transit, ensuring accurate diagnostic results.
Components of Viral Transport Medium:
Buffered Saline Solution – Maintains pH balance.
Protein Stabilizers (e.g., bovine serum albumin, gelatin) – Protect viral particles.
Antimicrobial Agents (e.g., gentamicin, amphotericin B) – Prevent bacterial/fungal growth.
Cryoprotectants (e.g., sucrose) – Helps in freezing/storage if needed.
Common Uses:
COVID-19 testing (SARS-CoV-2 detection)
Influenza (flu) testing
RSV (Respiratory Syncytial Virus) detection
Other respiratory or viral infections
Types of VTM:
Standard VTM – For routine transport at refrigerated temperatures (2–8°C).
Universal Transport Medium (UTM) – Compatible with multiple diagnostic methods (PCR, culture).
Molecular Transport Medium – Optimized for nucleic acid-based tests (like RT-PCR).
Storage & Handling:
Typically stored at room temperature or refrigerated.
Swabs should be placed in VTM immediately after collection.
Transported to the lab within 24–72 hours (or as per lab guidelines).
VTM ensures that viral samples remain stable until they reach the laboratory, improving the accuracy of diagnostic tests.
