Interim Guidelines for Collecting and Handling of Clinical Specimens for COVID-19 Testing

ABSTRACT

Added new language on ordering swabs and media, assessing specimens obtained through self-collection, and transporting specimens through pneumatic tube systems. View Previous Updates Key Points The type of specimen collected when testing for current or past infection with SARS-CoV-2 is based on the test being performed and its manufacturer’s instructions. Some of the specimen types listed below will not be appropriate for all tests. For initial diagnostic testing for current SARS-CoV-2 infections, CDC recommends collecting and testing an upper respiratory specimen. This guidance is intended for healthcare providers or health department staff who are collecting specimens from others in a healthcare setting or at the point-of-care. Guidance for self-collection of specimens can be found here. CDC has guidance for who should be tested, but decisions about who should be tested are at the discretion of State, Tribal, Local, and Territorial (STLT) health departments and/or healthcare providers. Testing for other pathogens by the provider should be done as part of the initial evaluation, as indicated, but should not delay testing for SARS-CoV-2, the virus that causes COVID-19.

For healthcare providers who are handling specimens, but are not directly involved in collection (e.g. handling self-collected specimens) and not working within 6 feet of the patient, follow Standard Precautions. Healthcare providers should wear a form of source control (face mask) at all times while in the healthcare facility. Healthcare providers can minimize PPE use if patients collect their own specimens while maintaining at least 6 feet of separation. For example, the provider should wear a face mask, gloves, and a gown.
