Methods and devices for nasopharyngeal carcinoma screening are disclosed. The method comprises providing a nasopharyngeal sample from a subject, isolating DNA from the sample, amplifying and detecting at least one EBV target sequence from the DNA using real-time PCR, wherein a real-time PCR cycle threshold number of less than or equal to 31.5 is indicative of the subject having nasopharyngeal carcinoma or a risk of developing nasopharyngeal carcinoma. The device for obtaining a brush biopsy sample comprises a longitudinal shaft having a first end and a second end, wherein at least two brush heads extend from the second end of the shaft. |
