Direct detection of human herpesvirus 6 DNA in serum by variant specific loop-mediated isothermal amplification in hematopoietic stem cell transplant recipients

A variant specific direct loop-mediated isothermal amplification (LAMP) method was developed to detect human herpesvirus-6 (HHV-6) variants in serum samples. Specific primers were designed against HHV-6 U86 gene. Initial validation analysis confirmed high specificity and sensitivity of the method. This method was shown to be highly reliable for monitoring active HHV-6 infection in hematopoietic stem cell transplant recipients.
