Ordering Guidance


This polymerase chain reaction (PCR) test is the test of choice for individuals with suspected measles infection and symptoms such as rash, cough, fever, and conjunctivitis at 0 to 5 days of rash onset.

 

If measles virus IgM antibody testing is positive (ROGM / Measles [Rubeola] Virus Antibody, IgM and IgG, Serum), this PCR test should be ordered to confirm the diagnosis of measles infection.
