Transport of asymptomatic inpatient NP and OP swabs before elective procedures

Hello,

Our hospital is testing asymptomatic inpatients scheduled for elective surgery or procedures for COVID-19 to verify they are negative before the procedure begins.  Can those OP or NP swabs be transported through the pneumatic tube system?

I know that the CDC does not recommend it for PUI or suspected patients.  However, I cannot find any guidance for the suggested COVID-19 testing before elective surgery or procedures on asymptomatic inpatients.  

Does anyone use the pneumatic tube system for those types of specimens?

Thanks!
