Measles Virus, Molecular Detection, PCR, Random, Urine
Use
This test is useful for identifying measles infection using random urine specimens. Measles virus is a single-stranded, negative-sense RNA paramyxovirus belonging to the genus Morbillivirus that causes acute respiratory illness. Laboratory confirmation of measles cases can be achieved through the molecular detection of measles virus RNA, providing increased sensitivity and specificity compared to serologic testing when specimens are collected early after rash onset.
Special Instructions
Not provided.
Limitations
A negative test result does not rule out infection with measles virus. It is crucial to use test results in conjunction with clinical findings and serologic test results for accurate diagnosis. False-negative results may arise from improper sample collection or viral variants. Additionally, samples that are frozen, heat inactivated, or containing preservatives will be rejected. The potential for false-negative results exists due to improper sample collection or viral variants.
