Test Name COVID SARS CoV2 RNA PCR
Specimen Requirements
Preparation of Patient:
Instruct patient that this is an uncomfortable procedure.
Container Type:
Dry swab in viral transport media. Acceptable swabs, sterile rayon, foam, polyester or flocked flexible-shaft nasopharyngeal swabs.
Specimen Type:
Nasopharyngeal
Specimen Collection:
- Tilt head back so the head is extended 70o Place hand on the back of patient's neck if able.
- Pass the swab gently through the more patent nostril about 3" to 4" into the nasopharynx keeping the swab near the septum and the floor of the nose parallel to the palette. Stop when resistance is met and do not force any further.
- Rub and roll the swab and leave in place for 10 - 15 seconds to absorb secretions before removing it.

SARS-CoV-2 Negative | SARS-CoV-2 target nuleic acids are NOT DETECTED by RT-PCR, a nucleic acid amplification method (NAAT), on the Cepheid GeneXpert system. Testing performed by Munson Healthcare, Traverse City, MI 49684 |
Clinical Significance
An outbreak of respiratory illness of unknown etiology in Wuhan City, Hubei Province, China was initially reported to WHO on December 31, 2019. Chinese authorities identified a novel coronavirus (2019-nCoV), which has resulted in thousands of conformed human infections in multiple provinces throughout China and in several Southeast Asian countries, Europe and more recently the United States. Cases of severe illness and deaths have been reported. The International Committee for Taxonomy of Viruses (ICTV) renamed the virus SARS-CoV-2.
