Meaning of Results

A negative test result indicates that SARS-CoV-2, the virus 

that causes COVID-19, was not detected in your sample. 

However, it is possible for this test to give a negative result 

that is not correct (false negative) in some people with 

COVID-19. Negative results do not preclude SARS-CoV-2 

infection and should not be used as the sole basis for 

treatment of an individual, including infection control 

decisions. If you have symptoms, contact a healthcare 

provider for additional testing. 

A positive test result indicates that SARS-CoV-2, the virus 

that causes COVID-19, was detected in your sample. It is very 

likely that you have COVID-19. Positive test results do not rule 

out bacterial infection or co-infection with other viruses. 

Individuals who test positive with the Metrix COVID-19 Test 

should self-isolate and seek follow-up care with a healthcare 

professional as additional testing may be necessary. 

The Metrix COVID-19 Test detects active COVID-19 infections 

and does not test for previous infections.

Intended Use

The MetrixTM COVID-19 Test (Metrix) is a single-use molecular in vitro diagnostic test for the 

qualitative detection of nucleic acid from SARS-CoV-2, the virus that causes COVID-19. This test 

is authorized for non-prescription home use with anterior nasal (nares) swab and saliva 

specimens, self-collected from any individual aged 14 years or older, or adult-collected from any 

individual aged 2 years or older, including individuals without symptoms or other epidemiological 

reasons to suspect COVID-19. 

This test utilizes nucleic acid amplification technology, similar to PCR, for the detection of 

SARS-CoV-2. SARS-CoV-2 viral RNA is generally detectable in anterior nasal (nares) swab and 

saliva samples during the acute phase of infection. 

Positive results indicate the presence of viral RNA, but clinical correlation with past medical 

history and other diagnostic information is necessary to determine infection status. Positive 

results do not rule out bacterial infection or co-infection with other viruses. The agent detected 

may not be the definite cause of disease. Individuals who test positive with the Metrix COVID-19 

Test should self-isolate and seek follow-up care with their physician or healthcare provider as 

additional testing may be necessary. 

Negative results from saliva samples are presumptive and should be confirmed by molecular 

testing of an alternative sample type if clinically indicated. Negative results do not preclude 

SARS-CoV-2 infection and should not be used as the sole basis for treatment or management 

decisions for the individual, including infection control decisions. Negative results should be 

considered in the context of an individual’s recent exposures, history, and the presence of clinical 

signs and symptoms consistent with COVID-19. Individuals who test negative and continue to 

experience COVID-19-like symptoms of fever, cough, and/or shortness of breath may still have 

SARS-CoV-2 infection and should seek follow-up care with their physician or healthcare provider. 

Individuals should report all results obtained with this product to their healthcare provider and 

the Aptitude secure web portal. This Aptitude secure web portal will report all test results 

received from individuals who use the authorized product to relevant public health authorities in 

accordance with local, state, and federal requirements using appropriate LOINC and SNOMED 

codes, as defined by the Laboratory In Vitro Diagnostics (LIVD) Test Code Mapping for 

SARS-CoV-2 Tests provided by the CDC.
