Specimen Requirements

Specimen Type	Preferred Container/Tube	Acceptable Container/Tube	Specimen Volume	Specimen Minimum Volume (allows for 1 repeat)	Pediatric Minimum Volume (no repeat)
Nasopharyngeal Swab (Preferred)	Universal Transport Media (UTM)	Viral Transport Media (VTM)	1 swab, in 3 mL	1 swab, in 3 mL	NA
Oropharyngeal (throat) Swab	Universal Transport Media (UTM)	Viral Transport Media (VTM)	1 swab, in 3 mL	1 swab, in 3 mL	NA
Combined NP swab and throat swab	Universal Transport Media (UTM)	Viral Transport Media (VTM)	1 swab, in 3 mL	1 swab, in 3 mL	NA

Collection Processing Instructions

Detection of Measles RNA is most successful when samples are collected on the first day of rash through the 3 days following onset of rash.

Detection of measles RNA by RT-PCR may be successful as late as 10-14 days after rash onset.

Collect samples as soon as measles disease is suspected.

Acceptable Specimen Types

Specimen Type(s): NP Swab, Throat Swab

Specimen Stability Information

Specimen Type	Temperature	Time
Swab in UTM	Refrigerated	<=72 hours
Swab in UTM	Frozen	3 months

Rejection Criteria

Calcium alginate swabs, Cotton swabs, Wooden shaft swabs, Dry swabs, Swabs in unacceptable transport media, Improper specimen type (e.g. Nasal swab, buccal swab, etc.), Specimens outside of the stability range.
