Test ID: SARS2    
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) RNA, Varies

Method Description Describes how the test is performed and provides a method-specific reference

The Abbott RealTime SARS-CoV-2 assay is performed using the FDA-approved, semi-automated Abbott m2000 system, which comprises the Abbott m2000sp sample preparation instrument and the Abbott m2000rt real-time PCR thermocycler. The Abbott mSample Preparation System kit is used on the Abbott m2000sp instrument, based on magnetic microparticle technology, to extract and purify viral RNA from clinical upper respiratory tract swab specimens and assay controls (negative and positive) placed in 96-well microtiter plate format. An internal control is also added to the extraction reagents and carried through the entire process in each specimen to ensure adequate extraction and subsequent target amplification have occurred free of inhibitory substances.


The PCR assay mastermix contains 3 sets of primers and TaqMan probes targeting sequences in the RdRp and N genomic regions of SARS-CoV-2 and the internal control armored RNA. Amplification and detection of target sequences are performed on the Abbott m2000rt thermocycler. Clinical samples containing SARS-CoV-2 would yield detectable signals for the RdRp and N sequences.(FAM-labeled fluorescent probes) as well as the internal control gene sequence (VIC-labeled fluorescent probe) (Package insert: Abbott RealTime SARS-CoV-2.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Sunday

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

3 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

5 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
