It depends on the type of specimen being transported: CDC recommends that respiratory specimens from patients with suspected or confirmed COVID-19 should not be transported through pneumatic tubes. At this time, this recommendation only applies to suspected or confirmed COVID-19 respiratory specimens. Examples of respiratory specimens include nasopharyngeal (NP) and oropharyngeal (OP) swabs, nasal mid-turbinate (NMT) swabs, tracheal and lower respiratory tract aspirates, bronchoalveolar lavage (BAL) specimens, and sputum. Based on currently available data, other types of specimens from patients with suspected or confirmed COVID-19, such as blood, urine, and feces specimens, are still acceptable to transport through pneumatic tubes. Facilities should ensure that all personnel who transport specimens via pneumatic tubes are trained in safe handling practices, specimen management, and spill decontamination procedures. Each facility should also evaluate its risks and determine the most appropriate biosafety measures and practices to implement.
