COVID-19 Diagnostic Test – DISCONTINUED

Oral and Nasopharyngeal (NP)

COVID-19 NP Collection

Testing done to identify COVID-19 uses real-time polymerase chain reaction (RT-PCR) technology to detect the presence of SARS-CoV-2 in respiratory samples.

Our COVID-19 Assay is listed on the FDA website as authorized under Emergency Use Authorization (EUA) guidelines.

SARS-CoV-2 Stool Analysis – DISCONTINUED

Coronavirus Stool Test/Screening and Surveillance

SARS-CoV-2 Stool Test

The SARS-CoV-2 stool test also uses RT-PCR technology to detect the presence of SARS-CoV-2 in stool.

 Not approved or evaluated by the FDA. This test is for investigational or Research Use Only (RUO).
Services provided are for laboratory testing only.

Research from around the world indicates that as many as 50 percent of patients who are positive for SARS-CoV-2 experience gastrointestinal complaints.1

Furthermore, evidence suggests SARS-CoV-2 is detectable in stool and its presence in stool may last for up to five weeks after clearance from the respiratory tract. A recent article published in Lancet states:

"Our data suggest the possibility of extended duration of viral shedding in faeces, for nearly 5 weeks after the patients' respiratory samples tested negative for SARS-CoV-2 RNA. Although knowledge about the viability of SARS-CoV-2 is limited, the virus could remain viable in the environment for days, which could lead to faecal-oral transmission, as seen with severe acute respiratory virus CoV and Middle East respiratory syndrome CoV. Therefore, routine stool sample testing with real-time RT-PCR is highly recommended after the clearance of viral RNA in a patient's respiratory samples. Strict precautions to prevent transmission should be taken for patients who are in hospital or self-quarantined if their faecal samples test positive."2

** The SARS-CoV-2 Stool Analysis is not diagnostic of COVID-19. COVID-19 disease can only be diagnosed with positive SARS-CoV-2 results on a respiratory sample.





COVID-19 is an infectious disease the World Health Organization has identified as a global pandemic. SARS-CoV-2 is a novel, single strand RNA virus that causes COVID-19.

According to the Centers for Disease Control, COVID-19 is mainly spread person to person through respiratory droplets produced when an infected person coughs or sneezes. Other means of virus transmission are possible as well. Asymptomatic patients or patients who have not yet presented with symptoms may transmit the virus to others, and the virus may also be spread by contacting a contaminated surface.

Symptomology Related to COVID-19

Some people with COVID-19 remain asymptomatic carriers of the disease, while others exhibit varying degrees of the following common symptoms:

  • Fever
  • Cough
  • Shortness of breath
  • Gastrointestinal Complaints
    • Diarrhea
    • Abdominal pain
    • Vomiting
  • Anorexia (loss of appetite)
