Measles Virus Information
Updated 3/21/2025
Instructions for the collection and submission of measles specimens for Real-Time RT-PCR testing at the Missouri State Public Health Laboratory:
The Missouri State Public Health Laboratory (MSPHL) provides laboratory testing services for individuals suspected of infection with Measles Virus. This testing has the ability to differentiate between measles wild-type viruses and the vaccine strain found in the Measles, Mumps, and Rubella (MMR) vaccine.
For general information on measles virus, please refer to the CDC’s measles website.
Important: Consultation with the Bureau of Communicable Disease Control and Prevention (BCDCP) is required prior to specimen collection or submission. You may contact BCDCP at 573-751-6113 during business hours or 800-392-0272 (24/7).
After contacting BCDCP (see above) and receiving testing approval, the samples should be collected in the manner outlined below and placed in an appropriate biosafety shipping container. Collection and shipping materials are provided by the Missouri State Public Health Laboratory and are available upon request once approval for testing has been granted.
Specimen Collection
Detection of measles RNA is most sensitive when respiratory specimens are collected within the first 3 days of rash onset. If unable to collect a respiratory specimen within 72 hours of rash onset, urine specimens may be collected in addition to respiratory specimens. Collection of a respiratory specimen along with a urine sample may improve test sensitivity, especially when collecting near the end of the RT-PCR collection window.
Once testing approval has been obtained from BCDCP, collect specimens as soon as possible after illness onset using the following criteria:
| When collecting specimen within 72 hours of rash onset, collect one of the following: | When collecting specimens between 4-10 days of rash onset, collect the following: |
