As the United States navigates the peak of the 2025-2026 influenza season, public health systems are facing significant pressure. The Centers for Disease Control and Prevention (CDC) estimates that by late December, the virus had already caused a...

Learn what a Viral Transport Medium (VTM) is, its key components, types (UTM, molecular transport medium), and its role in COVID-19, flu & RSV testing.

On June 26th, Huachenyang's general specimen collection kit (virus transport media) was officially certified by UKCA

The red liquid in the virus transport medium is called virus preservation fluid.

Since the virus itself will quickly lyse in vitro and thus affect the results of subsequent testing, virus transport media are required to preserve and transport the virus.

What are the benefits of scaling? What are the benefits of scaling? And does scaling hurt your teeth?

The preservation effect, limit of detection (LOD), microbial index, inactivation rate are the key indicators for determining the precision and sensitivity of COVID test.

The full name of VTM is Virus Transport Medium, which is mainly used for collecting, transporting and storing biological samples.

Single-use VTM kits are usually divided into two types, non-inactivated and inactivated.

The collected virus samples can be stored in a viral transport medium tube for a short time (within 72 hours) at 2-8℃.

Recently, the disposable virus transport media developed and produced by Huachenyang has obtained the FDA 510K certification in the United States

Only by preserving the collected samples in virus transport medium can the stability of the virus be maintained, thus helping the orderly execution of nucleic acid testing.

The 10-mix-1 virus transport medium has become an effective tool for covid-19 PCR assays because it improves the efficiency of sampling and detection while reducing the cost of detection.

The viral transport medium is designed for the inactivation of various viruses, such as 2019-ncov, influenza, and for the transportation of virus nucleic acids.
