The Ultimate List of Veterinary Diagnostic Companies in the US


Veterinary diagnostics companies play a major role in the health and safety of animals of all sorts, from our friendly household pets to the livestock that feeds millions of people every day. Some labs work on a small scale, helping to identify and diagnose illnesses in pets.


Others track, monitor, and offer guidance on how best to deal with epidemics like rinderpest or even animal-transmitted COVID-19.


For us people, Covid has been a nearly unprecedented disease event, but these kinds of epidemics and pandemics occur in animals all the time.


"According to the US Centers for Disease Control and Prevention (CDC), in 2019, eight major zoonotic breakouts were reported. Every year, thousands of Americans get sick from diseases spread between animals and people. Six out of every ten diseases in humans are zoonotic, making it crucial that nations strengthen their respective capabilities to prevent and respond to these diseases. This intensifies the need for regular monitoring of animal health, especially livestock." – Markets and Markets.

Truthfully, the veterinary diagnostics market is massive and growing every year. There has been a paradigm shift in the last decade, and the tools, techniques, and studies formerly dedicated solely to human medicine are expanding into animal medicine. For example, PCR testing – a primary component of modern human medicine – has become much more prevalent in veterinary medicine.



There are a lot of different veterinary diagnostic companies throughout the world. Some are national or global, headquartered in other countries, such as:



However, North America, in general, and the United States, in particular, is the center of the greatest developments and largest market share in veterinary diagnostics and sciences.


There's an ever-increasing population of pets and companion animals, an increase in food-producing livestock, increased dairy and meat consumption year over year, and more, all contributing to an explosion of veterinary diagnostic companies in the United States.


"Food and animal safety is one of the major concerns that can be made reliable based on the early detection of animal diseases using effective diagnostic tools. The demand for a safe and high quality of animal protein is likely to rise significantly over the coming years due to the concomitant increase in the diet conscious population globally. The continuous rise in the demand for animal protein is likely to contribute remarkable for the growth of animal diagnostics market size." – Fortune Business Insights.

Veterinary diagnostic labs can be broadly divided into two groups: private companies and government-associated facilities. Picking the right lab for any given need can be an important part of diagnostics and treatment for vets of all sorts, so it's a good idea to both have a reference list on hand and establish relationships with the labs best situated to help your practice with your most common needs.


List of NAHLN-Approved Laboratories


To start, let's run down the list of labs approved by the NAHLN. First, though, what is the NAHLN?


The NAHLN stands for the National Animal Health Laboratory Network. It is a cooperative effort between two U.S. Department of Agriculture (USDA) agencies, the Animal and Plant Health Inspection Service (APHIS) and the National Institute of Food and Agriculture (NIFA), along with the American Association of Veterinary Laboratory Diagnosticians. The NAHLN is a group of veterinary laboratories across the United States that are designed to provide comprehensive and coordinated diagnostic testing services for animal diseases.


In other words, it's a list of labs approved by the government to receive funding, provide certified testing, and more.


You can read more information, as well as browse lists by state, on this page. Alternatively, you can browse this list of animal diseases and find labs certified to diagnose, monitor, and treat them or provide recommendations for the mitigation or handling of an epidemic or outbreak.

The National Animal Health Laboratory Network (NAHLN) is vital for veterinarians. It aids in monitoring and addressing animal health crises, such as major disease outbreaks, through swift detection and response. NAHLN labs provide essential diagnostic services and develop innovative testing strategies. They also offer training, ensuring veterinary professionals are current with the latest techniques. Fundamentally, NAHLN safeguards the health of the nation's livestock, thus protecting our food supply and public health while bolstering veterinarians' ability to ensure animal welfare.

As you can see, there are quite a few of these labs on their site. However, this only scratches the surface. Many of these aren't private companies and those that tend to be affiliated with health networks. Private companies form a much longer and more varied list.


Private Companies in the United States Providing Veterinary Diagnostic Services


Depending on where you look, you can find widely varied lists of veterinary service companies, many of which provide diagnostic services. These can range from extremely narrow specialties, like Vidium providing diagnostic services specifically for canine cancers, all the way to global companies providing medical technology, veterinary services, comprehensive laboratory work, research and development, and much more.

It's not surprising.



Recent estimates place the veterinary diagnostic industry as a $2.8 billion dollar industry and growing, with predictions of growth to $4.4 billion by 2027. It's no wonder that everyone from major pharmaceutical and medical device manufacturers to the latest starry-eyed Silicon Valley startups is looking into the space.


It would be virtually impossible to list every company operating in the veterinary diagnostic services industry. There are two reasons for that. The first is that there are tons of them. Lusha, a business analytics and B2B contacts company has a database listing over 1,200 of them.



Secondly, they are changing rapidly.


New companies enter the market, old companies fold, some are bought and merged, others are renamed, and the entire space is constantly in flux. Any list we publish would need to be updated almost immediately shortly after we publish it.


That said, we can still talk about some of the major players in veterinary laboratory services. The most prominent companies in the United States are:

A larger selection of other companies providing some manner of services in veterinary diagnostics include:

Many of these are developers of specific technologies or processes that they then license out to other diagnostics companies for use in both human and animal diagnostics and medical services. LightDeck, for example, makes a machine used in diagnostics and develops a series of protocols to test for various issues in both humans and animals.


Is It Important to Know Your Labs?


If you're a pet owner, the chances that you'll deal with a veterinary diagnostics lab directly are slim. Many of these laboratories only deal with animal healthcare systems or veterinary service providers directly and don't burden themselves with customer service directly relating to pet owners. Many more don't even do that; they're vendors for equipment or consumables and work with other diagnostics labs.


As a veterinary services provider, is it important for you to know this list of labs and which is right for each of your clients? Not entirely.


Veterinary services have a lot on their plate. As a frontline service, you interface between a variety of different veterinary healthcare providers and pet owners. Your job isn't necessarily to know how to identify every issue, solve every problem, and operate every mechanism to perform every test. You need to know enough to diagnose common issues, and you can specialize in more niche issues, but you'll never know everything. No one can.


Instead, your role is to know who to talk to when an issue comes up. Which company provides testing and diagnostics for a given issue? Who do you send a test to, how much will it cost your client, and is it a valuable test to have performed? You're a filter as much as you are a doctor.


To that end, it's worth knowing some labs, but you'll only need to know some of them.

Generally, you want to know the kinds of common issues you might encounter (like pet cancers, dermatology problems, or local illnesses going around) and identify labs that can help diagnose, monitor, and treat those specific issues.


Our recommendation is to look for labs relatively local to you and a few of the more "prestige" labs that provide top-of-the-line services. That way, you can offer connections to the best quality care possible, and to affordable care, without jeopardizing the services you provide.


Similarly, reviewing the labs you talk to every couple of years can be a good way to keep on top of the industry and refresh your knowledge and contacts.

That's where we come in. For tricky cases in, for example, canine cancers, we have connections to a variety of diagnostic services and labs, as well as experts on hand who can offer advice, opinions, and next steps to take.
