A blood test can be used to help diagnose a range of conditions in dogs. Depending on the type of test recommended by your veterinarian, a blood test can provide insight into your dog’s overall health.
Commonly performed tests include a complete blood count (CBC), which evaluates the number of red and white blood cells, as well as their size and shape. A biochemistry panel checks the levels of enzymes, proteins, electrolytes, and hormones in your dog’s blood and gives an indication of their organ health.
A urinalysis indicates the presence of an infection and also helps identify any underlying issues, such as diabetes. Other tests that can be performed include a thyroid panel, to check for hormones associated with the thyroid gland, and a coagulation panel, to assess blood clotting ability.
In addition, testing for the presence of heartworm, tick-borne illnesses, and other parasites can be done via blood tests.

What cancers are detected by blood tests in dogs?
Blood tests are among the most common diagnostic tests used to check for many different types of cancer in dogs. A veterinary visit might include a complete blood count (CBC) and/or chemistry profile.
By examining the results of these tests, veterinarians can identify and pinpoint cancer that may be present.
Although not all types of cancer can be detected with a blood test, some of the most common include lymphoma, melanoma, leukemia, and mast cell tumors.
Lymphoma is a type of cancer that originates in the lymphatic system. It is usually characterized by abnormally high numbers of lymphocytes—a type of white blood cell—in the bloodstream. Symptoms of lymphoma may include enlarged lymph nodes, anemia, and/or decreased appetite.
A CBC can be used to identify and monitor high lymphocyte counts associated with this type of cancer.
Melanomas are a type of skin tumor. Blood tests aren’t able to detect melanoma directly, but they can be used to monitor the spread of the tumor or rule out the presence of other types of cancer. A CBC might reveal abnormally low red blood cell counts, anemia, or low white blood cell counts associated with melanoma, while a chemistry profile can provide results concerning other abnormalities such as elevated levels of liver, kidney, or pancreas enzymes.
Leukemia, a blood cancer, is usually manifested by low red blood cell counts and low platelet counts. Abnormal numbers of circulating white blood cells are also commonly seen. By using a CBC and/or a chemistry profile to check for these values, veterinarians can check for the presence of leukemia.
Mast cell tumors are a type of skin cancer. Because of their location and the fact that they don’t typically spread to the lymph nodes, they don’t always show up on a CBC. However, a chemistry profile may reveal that the dog has elevated liver enzymes, a sign that a mast cell tumor is present.
While blood tests alone may not be able to provide a definitive diagnosis, many cancers can be identified by examining the results of these tests. Veterinarians may then use other tools such as X-rays, ultrasound, and biopsies to help diagnose cancer and determine the best treatment plan.
What would show up in a blood test?
A blood test is used to measure various components of the blood, such as red and white blood cell count, hemoglobin, blood clotting factors, electrolytes, blood sugar, cholesterol and triglycerides, enzymes, human immunodeficiency virus (HIV) antibodies, hormones, and antibodies to particular infections.
Depending on the type of test being performed and the medical condition, other components may be tested as well. For example, a complete blood count (CBC) might measure red and white blood cell count, platelet count, hematocrit, and hemoglobin.
A chemistry panel will measure electrolytes, glucose, cholesterol, triglycerides, and enzymes such as aspartate transaminase (AST) and alanine transaminase (ALT). Some tests may measure other components such as vitamins, proteins, and prothrombin time (PT) and partial thromboplastin time (PTT).
Certain blood tests may require fasting before testing, as certain components may be altered when the body has recently ingested foods or drinks—especially those that contain carbohydrates and fats.
Would a tumor show up in blood work for dogs?
No, a tumor will not show up in blood work for dogs. Blood tests in dogs are mainly used to measure organ function (such as the liver and kidney) and electrolyte levels. They can also look for evidence of infection, like high white blood cell count or low red blood cell count.
Sometimes blood tests can show evidence of underlying diseases or conditions, such as diabetes, heart or lung problems, or thyroid issues. However, tumors are not detected through conventional blood tests in dogs.
There are other tests that may be recommended by a veterinarian to diagnose a tumor in a dog, such as ultrasounds, x-rays, CT scans, or magnetic resonance imaging (MRI). A biopsy may also be necessary to accurately diagnose the tumor.
Does dog blood work show kidney problems?
Yes, dog blood work can show kidney problems. In a comprehensive blood work panel for dogs, blood tests are run to check a dog’s creatinine and BUN levels. These two values provide an indication of the overall health of the dog’s kidneys.
If either of these levels are higher than normal, it could suggest that the dog is having issues with their kidneys, such as inflammation, infection, or even kidney failure. In certain cases, albumin and urine tests may also be run to aid in diagnosing any potential kidney issues.
Can blood work show signs of tumors?
Yes, blood work can be an indicator of tumors. Depending on the type of tumor, blood tests can detect elevated levels of certain substances in the bloodstream. An elevated level of particular substances may be a sign of certain types of tumors, including some cancerous tumors.
For example, a high calcium level might indicate a parathyroid gland tumor or a prostate cancer-specific antigen (PSA) test might reveal prostate cancer. Additionally, abnormal hemoglobin levels may be evidence of red blood cell tumors.
Other conditions that may present with abnormal blood tests include lymphoma, leukemia, and skin cancers. Your doctor can use the results of your blood work to order further tests, like imaging scans, to diagnose a tumor and create an appropriate treatment plan.
What are the symptoms of lymphoma in dogs?
Lymphoma is a type of cancer that affects the lymph nodes in dogs. It is most commonly seen in middle-aged to older-aged dogs. The most common symptoms of lymphoma in dogs include enlarged lymph nodes, enlarged spleen, enlarged liver, weight loss, decreased appetite, lethargy, vomiting, diarrhea, and pale gums.
Other symptoms can include difficulty breathing, hives, skin bumps, coughing, and decreased activity. If lymphoma is suspected, your veterinarian will perform a physical examination, order blood and urine tests, and obtain a biopsy of affected tissue.
This can help to confirm the presence of lymphoma and determine the best treatment plan for your dog. Treatment typically involves chemotherapy, surgery to remove affected lymph nodes, and/or other medications, such as antibiotics or steroids.
Although lymphoma can be serious, many dogs respond well to treatment and live normal lives.
How are tumors detected in dogs?
Tumors in dogs can be detected by visual examination or through a combination of diagnostic tests. During a physical exam, the veterinarian may be able to feel a tumor, however, in some cases, tumors may be hidden beneath the skin or internal organs.
To confirm the diagnosis, diagnostic tests are performed. Common diagnostic tests used to detect tumors in dogs include x-rays, ultrasounds, CT scans, biopsies and blood tests. X-rays and ultrasounds are used to help detect tumors in the body, and can show if the tumor is arising from a bone or organ.
CT scans can provide a more detailed look at a tumor and its position within the body. A biopsy can provide a more definitive diagnosis and help in determining the type of tumor and the best course of treatment.
Blood tests can also be performed to help identify signs of cancer, such as increased white blood cell counts. Generally, veterinarians will recommend one or more tests to confirm a diagnosis of tumors in dogs.
How can you tell if your dog has a tumor?
These include visible physical signs such as lumps or bumps on the skin, difficulty breathing, lameness or limping, chronic coughing, sores that do not heal, trouble urinating or defecating, weight loss, and loss of appetite.
In addition, your dog may seem to be in pain, have difficulty sleeping, and/or experience lethargy or general weakness.
If you are concerned that your dog may have a tumor, it is important to visit your veterinarian right away. Your veterinarian can perform a physical examination, take X-rays of the area, and/or perform blood tests to help confirm a diagnosis.
If a tumor is found, your veterinarian may recommend additional tests, such as a CT scan or biopsy, to determine the best treatment and care options for your pet.
How do vets check for tumors?
Vets will typically use a variety of methods to check for tumors. Depending on the location of the tumor, the vet may first examine the area visually or palpate it to feel for irregularities. The vet may then order additional diagnostic tests such as x-rays, ultrasounds, or a computed tomography (CT) scan to gain a clearer picture of the area.
Blood and urine tests may also be ordered to check for additional medical conditions. In some cases, a biopsy or fine-needle-aspiration may be used. During a biopsy, a small sample of the suspicious tissue is taken and examined by a specialist in a lab.
For a fine-needle-aspiration, a veterinarian will use a needle and syringe to collect cells from the area to examine under a microscope. When the cancer has been confirmed by lab testing, the vet will likely order additional blood work and radiographs to evaluate the extent of the cancer.
The vet may also perform additional procedures such as a lymph node biopsy or an abdominal ultrasound if the tumor is located in an inaccessible location. Ultimately, the vet will use the information gathered by these tests to determine the best course of treatment for the pet.
How long does it take to get blood test results for a dog?
It depends on the type of blood test being done and the veterinary lab that is processing the results. Generally, basic complete blood count (CBC) results can take 1-2 days to be returned. Liver and kidney function tests can take a few days, while more comprehensive panels that include hormones and chemotherapy levels can take a few weeks.
If an immediate diagnosis is necessary, results can sometimes be expedited and returned within 24 hours; however, this may incur additional costs. In addition to the type of test and the laboratory, the turnaround time can also be affected by the frequency of sample submission, the number of samples in the queue before yours, the accuracy of the sample collection, the accuracy of the submission information, the presence of unusual or challenging elements that must be identified and some other variable factors.
How long do blood tests take at vet?
The length of time it takes to get a blood test result back from the vet can vary depending on many factors. If the vet chooses to send the sample to an outside laboratory, it can take anywhere from 3 to 10 business days to get the results back.
In addition, the complexity of the blood test and the method used to analyze the sample can also affect the turnaround time. For instance, a basic hemogram (CBC) or biochemistry panel could take several hours to complete, while a more complex test such as a thyroid or hormone panel may require 24 to 48 hours to get the results.
In some cases, the laboratory may even have to grow a culture before they can send the results back. If the vet has the in-house capabilities to run the tests, the results should be available right away.
However, the accuracy and sensitivity of these test results may be limited and not as reliable as tests sent to an outside lab.
How much does it cost to test a dogs blood?
The cost to test a dog’s blood can vary depending on the specific test that is being done. Generally speaking, most veterinary clinics will charge between $50-$150 per test, with tests for more complex conditions potentially being more expensive.
If the test is being done to diagnose a suspected medical condition, the cost is usually included in the overall cost of treatment. Additionally, if the test is being done annually or as part of a routine health check-up, the cost may be covered by pet insurance or discounts may be offered at the veterinary clinic.
Does a dog need to fast before blood work?
No, a dog does not need to be fasted before blood work. However, it is important to make sure the dog has not been eating for at least four hours prior to the test. This is because certain nutrients from food can change the test results, making them inaccurate.
Your vet will provide you with the best instructions on how to prepare your pet for their blood work. In addition, it is a good idea to make sure your pet does not get overly stressed before or during the procedure.
You can do this by taking them for a nice, calming walk prior to the appointment, as well as making sure they have an opportunity to go to the bathroom.
Is bloodwork for dog necessary?
Yes, bloodwork for dogs is necessary. Bloodwork, which can also be referred to as a blood chemistry panel, is a vital part of preventive care for all dogs. Regular blood tests can provide early detection of diseases, allergies, infections, and other conditions that are not always visible.
Bloodwork can provide insight into a dog’s overall health and can help veterinarians determine the best course of treatment for any existing or potential health issues. It can also provide insight into future risks or health concerns that may require attention before they become major problems.
Bloodwork can also be used to monitor your pet’s response to treatments, making it an important tool for tracking the progress of your pet’s health.
