Yes. The IDEXX SARS-CoV-2 (COVID-19) RealPCR Test for pets is available to veterinarians in North America and will continue to roll out across most of the world in the coming weeks, enabled by IDEXX Reference Laboratories, the company's worldwide network of more than 80 laboratories.

Complete testing information

Leading health authorities and IDEXX veterinarians agree that transmission of the SARS-CoV-2 virus is primarily person to person and advise against testing asymptomatic pets. In symptomatic pets, it is more likely that disease is caused by a more common respiratory infection than by COVID-19.

IDEXX's guidance, aligned with that of medical experts, is that veterinarians order the IDEXX SARS-CoV-2 (COVID-19) RealPCR Test after consultation with a public health authority (for example, a state public health veterinarian in the United States) and these three specific criteria are met:

• Pet is living in a household with a human who has COVID-19 or has tested positive for the SARS-CoV-2 coronavirus
• Pet has already been tested for more common infections, which a veterinarian has ruled out
• Pet (especially cats and ferrets) is showing clinical signs consistent with COVID-19
   

To rule out more common respiratory infections first, we suggest ordering one of these tests: 

Yes, in a limited number of cases. Positive results are confirmed internally in triplicate using the IDEXX test as well as three United States Centers for Disease Control (US CDC) assays. Positives have been confirmed by independent testing by the United States Department of Agriculture National Veterinary Services Laboratories (USDA-NVSL). A list of the positive cases are available at the link below:

IDEXX SARS-CoV-2 RealPCR Test: Positive cases

Yes. The IDEXX SARS-CoV-2 RealPCR Test targets a part of the virus’ genome which has not been affected by the mutations in the variants that have been discovered to date. As new strains are identified, IDEXX continues to monitor the genetic changes in the virus to ensure that our test maintains its diagnostic accuracy.

Experts continue to reassure pet owners there is low likelihood of pet infection and even lower likelihood of our pets serving as a source of infection. Leading public health authorities agree that COVID-19 is primarily a human disease that is transmitted by direct human-to-human transmission in respiratory droplets.^1-4 During the validation of the IDEXX SARS-CoV-2 RealPCR Test, IDEXX tested over 6,000 specimens for the COVID-19 virus. The specimens were submitted to IDEXX Reference Laboratories for respiratory tests of sick cats, dogs and horses in 17 different countries (February 14 – April 17, 2020). In April 2020, the IDEXX SARS-CoV-2 RealPCR Test became available for use in pets with clinical signs and known exposure to an infected human. Despite exponential growth in positive human cases globally, only a very limited number of cases have been identified in pet dogs and cats. To review a summary of positive cases detected by the IDEXX SARS-CoV-2 RealPCR Test, please click here.

While there is currently no evidence that dogs or cats play a role in transmitting the disease to humans, clinical evidence suggests there may be varying levels of susceptibility to infection in animals. Studies have demonstrated that cats and ferrets may be infected in experimental settings and transmit to other animals, while dogs are generally resistant to infection, likely due to species differences in their ACE-2 receptors.^7-9 

In isolated cases, reverse zoonotic (infected human to pet) transmission has been reported in cats, ferrets, and dogs.^10,11 Infection in cats and ferrets is often subclinical but may present with mild respiratory signs, fever and, in some cases, gastrointestinal signs. In these non-primary host species, infection seems to be shorter in duration than in humans. Although transient reverse-zoonotic infections have been sporadically reported in dogs living with COVID-19 infected humans, no clinical signs have been reported in these dogs.^10-13 Pets are not believed to play a role in transmitting COVID-19 to humans.^1-4

In addition to dogs and cats, natural infection (non-experimental) cases have been identified in mink, ferrets, gorillas, and large felids, including lions, snow leopards, tigers, and cougars. Unlike pets, mink have been identified as a susceptible species which could potentially pose as a reservoir of infection and viral mutation when SARS-CoV-2 is introduced by infected humans into a high population density situation such as a mink farm.

Throughout the course of the COVID-19 pandemic, there have been various theories and myths about how this virus might have emerged in humans. According to leading infectious disease expert Dr. Scott Weese, the latest theory that humans got COVID-19 because dogs ate coronavirus-infected bats is speculative at best.

• There is currently no evidence that dogs or cats play a role in transmitting the disease to humans. And, there is no evidence dogs were the origin of SARS-CoV-2, the coronavirus strain responsible for the coronavirus disease 2019 (COVID-19) respiratory outbreak in humans. 
• Leading public health authorities (including the AVMA, CDC, and OIE) agree that COVID-19 is primarily a human disease that is transmitted by direct human-to-human transmission in respiratory droplets.
• Research and current information indicate that there can be varying levels of susceptibility to short-lived infections in pets, particularly cats and ferrets. Experimental infection studies have shown that dogs are generally resistant to infection.

Coronaviruses are a large family of viruses consisting of multiple subgroups of viruses that are commonly found in humans as well as other mammals, birds, and reptiles. Common coronaviruses causing respiratory or gastrointestinal disease in our veterinary patients are alpha coronaviruses. 

• The IDEXX SARS-CoV-2 (COVID-19) RealPCR Test detects SARS-CoV-2 in pets based on the published genetic sequences of the virus from the human outbreak. IDEXX's guidance, aligned with that of medical experts, is that veterinarians order the IDEXX SARS-CoV-2 (COVID-19) RealPCR Test after consultation with a public health authority (for example, a state public health veterinarian in the United States) and these three specific criteria are met:
  • Pet is living in a household with a human who has COVID-19 or has tested positive for the SARS-CoV-2 coronavirus 
  • Pet has already been tested for more common infections, which a veterinarian has ruled out 
  • Pet (especially cats and ferrets) is showing clinical signs consistent with COVID-19 
     
• The IDEXX Comprehensive Canine Respiratory Disease (CRD) RealPCR Panel includes the IDEXX RealPCR Test for canine respiratory coronavirus. Canine respiratory coronavirus contributes to canine infectious respiratory disease complex (also known as infectious tracheobronchitis or “kennel cough”). This panel is not a test for the SARS-CoV-2 virus, which causes COVID-19. 
• IDEXX Comprehensive Diarrhea RealPCR panels include IDEXX RealPCR tests for canine, equine, ferret, and feline enteric coronavirus. Enteric coronaviruses can cause intestinal infections leading to diarrhea, particularly in younger animals. These panels are not a test for the SARS-CoV-2 virus, which causes COVID-19. 
• IDEXX FIP Virus RealPCR Biotype (Add-on to Feline Coronavirus RealPCR Test) detects the most common mutations causing feline infectious peritonitis (FIP), a mutated form of feline enteric coronavirus resulting in severe, generally fatal, systemic inflammatory disease. This test is not a test for the SARS-CoV-2 virus, which causes COVID-19. 
• IDEXX IBV Ab Test detects gamma coronavirus. Infectious bronchitis virus (IBV) causes a highly contagious viral disease in chickens that is usually manifested as a respiratory condition. This test facilitates the monitoring of immune status in large flocks. This test is not a test for the SARS-CoV-2 virus, which causes COVID-19.
• IDEXX RealPCR TGEV RNA Mix tests for swine enteric coronaviruses. Severe outbreaks of enteric coronaviruses, characterized by acute and rapidly spreading diarrhea, are threatening swine operations worldwide. This test is not a test for the SARS-CoV-2 virus, which causes COVID-19.
• IDEXX Rota-Corona-k99 Ag Test is an enzyme-linked immunosorbent assay (ELISA) that differentiates between rotavirus, coronavirus, and E. coli infections by antigen detection. Bovine coronaviruses may cause diarrhea in calves. They can also cause winter dysentery, with bloody diarrhea, mild respiratory signs, and decreased production in adult cattle. This test is not a test for the SARS-CoV-2 virus, which causes COVID-19.

Our understanding of COVID-19 transmission has been rapidly evolving. Leading experts (including the AVMA, CDC, and OIE) still feel that pets do not play a significant role in transmitting COVID-19 to humans. However, there is growing evidence that pets can be at risk of being infected with the SARS-CoV-2 virus following exposure to infected humans. In the past month there have been several isolated reports of reverse-zoonotic transmission to animals, including two dogs and a cat in Hong Kong, a cat in Belgium and a tiger (and possibly other large felids) in the Bronx Zoo. There is evidence that at least some of these cases are true infection, not just environmental contamination. In addition, recent experimental infection studies have demonstrated that cats and ferrets can be infected with the SARS-CoV-2 virus and can transmit infection to other cats or ferrets. Infected cats and ferrets may be asymptomatic or may have fever, mild respiratory signs or GI signs. A serologic survey suggests that infection in cats may be more common than previously suspected. Dogs appear to be more resistant to infection and especially to clinical disease compared to cats or ferrets, likely due to differences in their ACE-2 receptors which the virus uses to enter the cells.  

As this new information becomes widely recognized, opinion is shifting as to whether testing of pets is indicated. The World Organization for Animal Health (OIE) states “If a decision is made as a result of a risk assessment to test a companion animal which has had close contact with a person/owner infected with COVID-19, it is recommended that RT-PCR be used to test oral, nasal and fecal/rectal samples.”  

Veterinarians (including public health officials) are reaching out to IDEXX asking for availability of the IDEXX SARS-CoV-2 RealPCR test for use in testing pets from COVID-19 infected households where the pets (especially cats and ferrets) have clinical signs consistent with COVID-19 and diagnostics for more common veterinary pathogens have been ruled out. Testing of nonclinical pets is not recommended by leading experts other than at the recommendation of a public health authority.

IDEXX's guidance, aligned with that of medical experts, is that veterinarians order the IDEXX SARS-CoV-2 (COVID-19) RealPCR Test after consultation with a public health authority (for example, a state public health veterinarian in the United States) and these three specific criteria are met:

• Pet is living in a household with a human who has COVID-19 or has tested positive for the SARS-CoV-2 coronavirus
• Pet has already been tested for more common infections, which a veterinarian has ruled out
• Pet (especially cats and ferrets) is showing clinical signs consistent with COVID-19
   

Testing of symptomatic pets in COVID-19 infected households may not always be indicated as clinical signs, when present, may be mild and transient. The IDEXX SARS-CoV-2 (COVID-19) RealPCR Test may be considered when investigating respiratory disease in ferrets or cats after more common respiratory infections have been ruled out. Consultation with a local health authority prior to considering testing for COVID-19 in a pet is recommended. Testing should be limited to those animals with known or strongly suspected COVID-19 exposure. For cats presenting with respiratory signs, a Feline Upper Respiratory Disease (URD) RealPCR Panel should be considered prior to evaluating for SARS-CoV-2 infection, even in cats from a COVID-19 positive household. Ferrets presenting with respiratory signs should be evaluated with an Influenza Virus RealPCR Panel in addition to testing with the IDEXX SARS-CoV-2 (COVID-19) RealPCR Test.

Although the IDEXX-SARS-CoV-2 (COVID-19) RealPCR Test targets the same nucleocapsid gene as the CDC assays, the test is not the same as the human tests. The IDEXX COVID-19 test has been specifically designed for use in veterinary patients, to avoid cross-reactivity with veterinary coronaviruses, and to perform on the standardized IDEXX RealPCR platform. 

IDEXX Reference Laboratories is a veterinary diagnostic laboratory only. We are not approved for human testing and will not process any samples showing such markers. 

It is illegal and unethical to send human specimens to IDEXX Reference Laboratories. 

U.S. law, specifically the U.S. Laboratory Improvement Amendments (42 U.S.C. §263a – “CLIA”) sets forth strict certification requirements for accepting human materials. IDEXX operates veterinary laboratories only, and hence our laboratories are not CLIA licensed and may not handle human materials (similar rules apply in other countries in which IDEXX operates). Accordingly, any submission of human materials to IDEXX may contravene the laws of the United States or other countries, and is potentially subject to criminal sanction. 

Knowingly sending human specimens to IDEXX Reference Laboratories for testing, or knowingly mislabeling specimens, may constitute fraud, dishonesty or general unprofessional conduct under applicable veterinary licensing requirements, and could result in monetary fines or suspension or revocation of a veterinary license. See for example 16 CCR §2006 (incorporating California Veterinary Medical Board Disciplinary Guidelines).

No. The IDEXX SARS-CoV-2 (COVID-19) RealPCR Test was developed specifically for use in animals and was carefully designed to avoid cross reactivity with other veterinary-specific coronavirus strains that infect pets. IDEXX Reference Laboratories are designed for veterinary diagnostics only. Given our focus on and expertise in veterinary diagnostics, our laboratories are not approved for handling human specimens.

OPTI Medical Systems ​
The company's human health business, OPTI Medical Systems, is advancing support of human COVID-19 testing with the development of a PCR test kit, enabled by IDEXX's expertise in livestock PCR test development and manufacturing. ​

OPTI Medical has validated a PCR test kit specifically developed for use in humans and intended primarily for limited initial distribution to existing customers that are active in human COVID-19 testing. This initiative is in an early stage of development.

Not currently. Although of academic interest in differentiating environmental contamination from transient infection in pets, an antibody test for pets has less value in identifying and managing infection than a PCR test which can test for active infection. Testing for antibodies against the SARSCoV-2 virus shows some promise in human medicine to identify people who have already been exposed to COVID-19 in the past and therefore are possibly at lower risk of catching COVID-19. It is proposed that this may help in determining which essential workers would be safest to serve in high risk areas. Pets appear to get only rarely infected, and when they do, the infection is commonly nonclinical or mildly clinical and short-lived. Pets are also not believed to play a role in transmitting disease to humans at this time.

Coronaviruses are a large family of viruses consisting of multiple subgroups of viruses that are commonly found in humans as well as other mammals, birds, and reptiles. Coronaviruses get their name from their spiked surface proteins, or corona, which is Latin for crown. Coronavirus infections in animals, for example feline enteric coronavirus, are commonly alpha coronaviruses.

The SARS-CoV-2 virus, which causes Coronavirus disease 2019 (COVID-19), is a unique coronavirus that infects the human respiratory tract and is different from previously identified coronaviruses infecting humans or veterinary patients. SARS-CoV-2 causes COVID-19 respiratory disease in humans and is a beta coronavirus.

COVID-19 was first detected in China with an initial outbreak in the city of Wuhan. SARS-CoV-2 is believed to have originated from bats. Since its emergence in late 2019, COVID-19 has spread to locations around the globe.
