HHV6 R-GENE®

Real-time PCR kit for the detection and quantification of Human Herpes Virus 6 (HHV6) DNA

  • Reliable quantification of HHV-6A & HHV-6B without subtyping
  • Ready-to-use kit including internal control and quantification standards
  • Validated on major extraction and amplification platforms as well as on most relevant specimen types

HHV6 R-GENE® advantages

Human herpesvirus 6 (HHV-6) can cause various clinical syndromes including severe infections in immunocompromised patients, particularly in allogeneic hematopoietic stem cell transplant (HSCT) recipients. HHV-6 reactivation has been associated with numerous post-transplant complications including graft-versus-host-disease, encephalitis, interstitial pneumonitis, delayed engraftment, fever, and skin rash, responsible for morbidity and mortality. HHV-6 DNA detection and quantification is useful for diagnosing and monitoring infections.

HHV6 R-GENE® offers rapid and specific detection even prior to clinical symptoms, making it an ideal solution. This helps improve options for management, measure the effectiveness of treatment, and monitor for relapse.

Everything you need in one kit

The HHV6 R-GENE® kit is a ready-to-use molecular detection and quantification kit. It measures the viral load of HHV6 using real-time PCR after viral DNA extraction. The 5’ nuclease hydrolysis probe technique enables amplification and simultaneous detection of a specific region of the HHV6 genome.

  • 4 Quantification Standards ensure accurate measurement of HHV6 viral load
  • Sensitivity Control validates the assay’s performance
  • An Internal Control (IC2) checks the extraction process and the presence of amplification inhibitors in the sample
  • Assay includes all necessary reagents optimized to detect and quantify HHV6 for in vitro diagnostic use

Easy procedure

Using the HHV6 R-GENE® kit is easy. Just add the extracted DNA sample to the ready-to-use PCR master mix and start the reaction on the appropriate Real-Time PCR thermocycler, following the optimized cycling program described in the “Instructions For Use”.

Fast facts on HHV-6

What is HHV-6?

Human herpesvirus 6 (HHV-6) is a DNA virus, member of the Herpesviridae family, that includes two species: HHV-6A and HHV-6B. This is an ubiquitous virus with a seroprevalence reaching more than 90% in adult population. Primary infection most often occurs before 2 years old, causing roseola infantum. After primoinfection, HHV-6 remains latent in various cells including monocytes, macrophages, endothelial cells, bone marrow progenitors and central nervous system cells. As a noticeable difference with other human herpesviruses, genomic HHV-6 DNA can be integrated into the cell chromosomes (ciHHV-6) in about 1% of the general population.

Who is most at risk?

During specific pathological states (e.g. immunocompromised patients), HHV-6 can be reactivated and can impact several organs. In transplant patients, HHV-6 reactivation may result in a wide clinical spectrum: bone marrow suppression, graft rejection, pneumonitis, encephalitis, hepatitis, fever, skin rash... Among these patients, hematopoietic stem cell transplant recipients are particularly at risk of developing an HHV-6 reactivation (about 50% within the first 4 weeks after cell transfer). Severe complications linked to this active infection include delayed engraftment, graft versus host disease, and HHV-6 encephalitis.

What are the benefits of HHV-6 testing?

HHV-6 DNA detection and quantification with real time PCR assays is useful for diagnosing and monitoring HHV-6 infections. It offers rapid and specific detection and quantification, even prior to clinical symptoms, to help improve options for management, measure the effectiveness of treatment, and monitor for relapse.
