Abstract: This invention provides a new and more sensitive methodology for multiplex real time PCR testing of any genetic materials. The method is best illustrated here with the detection and diagnosis of Severe Acute Respiratory Syndrome (SARS) but can be applicable to any other usage where more sensitivity is required. It can be combined with the usual multiplex real time PCR test for further confirmation and multiple parameter assessment of SARS or other diseases. A kit form is provided for the detection of SARS by this methodology, but equally applicable to other diseases or testing conditions.

Abstract: The present invention features methods for diagnosing, detecting, monitoring and determining the prognosis of Epstein Barr virus associated cancers in a patient by detecting or measuring EBV DNA present in the serum or plasma of the patient followed by EBV subtyping of polymorphisms. The sensitivity of the circulating EBV DNA serves as a good screening tool while the EBV subtyping of polymorphism confirms the prognosis or diagnosis of EBV associated malignancies. The present invention also features diagnostic kits comprising suitable reagents for the above tests.
