Measles (Rubeola), PCR, Urine
Use
The Measles (Rubeola) PCR, Urine, test is used as a supplemental method for detecting measles in patients with compatible symptoms (fever, malaise, cough, coryza and/or conjunctivitis).
Special Instructions
CDC recommends submission of a nasopharyngeal swab, throat swab, or urine for PCR testing in patients displaying clinical features compatible with measles. However, nasopharyngeal or throat swabs are preferred over urine specimens for optimal results. Urine specimens should be collected as soon as possible after the development of rash to maximize the sensitivity of measles RNA detection.
Limitations
A negative test result does not rule out infection with the measles virus. Results should be interpreted in conjunction with clinical findings and serological testing. Improperly collected samples may result in false negative results, and PCR assays may be impacted by viral variants leading to reduced sensitivity or false negatives. This test was developed by Labcorp and has not been cleared or approved by the FDA. Nasopharyngeal or throat swabs are preferred over urine specimens.
