A new protocol for CMV LAMP with an additional heat denaturation step was developed. While the sensitivity of the original CMV LAMP method was 500 copies/tube, sensitivity was increased by up to 100 copies/tube by additional heat denaturation. CMV DNA was detected in 103 of350 samples (29.4%) by the original CMV LAMP procedure and 148 of350 samples (42.3%) by the new CMV LAMP protocol. When the pp65 antigenemia assay was used as the standard method, the sensitivity, specificity, PPV, and NPV of the new protocol were 92.9%, 77.7%, 62.2%, and 96.5%, respectively.
