Prioritize Patient Health with TTV Viral Load Monitoring

TTV (Torque Teno Virus) viral load monitoring is revolutionizing clinical diagnostics by providing crucial insights into patient health, especially for those with compromised immune systems, such as solid organ transplant recipients. This advanced diagnostic tool can be essential for assessing both infection and rejection risks in transplant patients, ensuring optimal care and treatment. Utilizing the stable analyte of viral DNA and the highly precise qPCR analysis method, TTV viral load monitoring can offer accuracy and a broad dynamic range.

TTV viral load in plasma indicates the intensity of host immunosuppression and is associated with the risk of allograft rejection and infectious disease.

  • Higher TTV viral load is associated with a higher risk of infection, lower risk of Rejection
  • Lower TTV viral load is associated with a higher risk of rejection, lower risk of infection

TTV Viral Load for Monitoring the Net State of Immune Suppression

TTV - Torque Teno Virus

Risk Stratification for Solid Organ Transplant Recipients

Improved and standardized methods are needed to monitor the net state of immunosuppression in solid organ transplant recipients.

Torque Teno Virus (TTV) is a non-pathogenic virus that has been widely studied as a biomarker of the net state of immunosuppression.

  • Increases in TTV viral load have been widely correlated with a decreased risk of allograft rejection and an increased risk of infections.
  • For each 10-fold increase in TTV load, rejection risk decreases by 25% and infection risk increases by 4%
  • The proposed TTV target range for balanced immunosuppression is 106 to 108 copies/mL.
