Measles Testing Guidance
If measles is suspected, IMMEDIATELY call IDPH at 800-362-2736; or after hours call 515-323-4360. State epidemiology personnel will advise on the appropriate testing to be ordered and specimen transport to the State Hygienic Laboratory (SHL). Currently, two different tests are available: serology testing for measles virus IgG and/or IgM and real time PCR for measles. Serology testing is performed at SHL. PCR is sent out to a CDC regional reference laboratory.Blood Specimen for Serologic Testing
Serology-collection for adults, 4 to 6 ml of blood in a red top or serum separator tube (SST), for infants, 2 to 3 ml of blood in a red top or serum separator tube (SST). Send to SHL on a cold pack, (not frozen) with a completed Serology test request form.
Throat Swab for RT-PCR
Rub the tonsils and posterior pharynx with Dacron-tipped plastic swab. Place the swab in tube containing M4 transport medium provided. The transport medium is kept cold and should be sent on a cold pack. Specimens received at SHL will be sent to a CDC regional reference laboratory for testing as appropriate. Please submit a completed Viral and Bacterial PCR and DFA test request form and write in "PCR for measles."
Ordering
Testing for suspect measles cases that has been approved by IDPH will be conducted at no charge. For additional information, contact the State Hygienic Laboratory at (319) 335-4500.
