LABORATORY RESOURCES

Specimen Collection, Storage, and Shipment (CDC)

Laboratory Testing (CDC)

Collecting and shipping specimens from suspected measles cases:

• CDC recommends that either a nasopharyngeal swab, throat swab, or urine specimen as well as a blood specimen be collected from all patients with clinical features compatible with measles.
• Nasopharyngeal or throat swabs are preferred over urine specimens.

For U.S. patient specimens:

• Please contact your state or local health department to determine where to submit specimens and how to ship them.

• The CDC Infectious Diseases Laboratories provide guidance for measles specimen collection, storage, and shipment. Refer to the Infectious Diseases Laboratories Test Directory entry for each test for instructions on specimen collection, storage, and shipment as well as points of contact for the tests.

• Serology (serum specimen collection)
  Measles Serology (Test CDC-10244)
  Measles Avidity (Test CDC-10248) *currently unavailable

• Real-time RT-PCR (nasopharyngeal, throat swabs, and urine specimens)
  Measles Detection (Test CDC-10543)
  Measles Vaccine Virus Detection (Test CDC-10528)

• Specimens submitted for testing from within the U.S. must be accompanied by CDC Form 50.34. Submitters are encouraged to use the CDC Specimen Test Order and Reporting (CSTOR) Web Portal to submit specimens.

For International Specimens:

• For international submissions, please contact Dr. Paul Rota, Dr. Bettina Bankamp or Dr. Stephen Crooke.
• For international shipments, refer to the Infectious Diseases Laboratories Test Directory entry for each test, see links above.
