Test Code MEASR Measles Virus, Molecular Detection, PCR, Throat


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.
