It was really unlucky that the dog caught a cold just two days after I got it home, so I decided to go to the hospital and see a veterinarian.

After explaining the situation, I took my temperature, performed auscultation, and did a blood routine.

How much does it cost to do a blood test? Isn’t it just a cold? Prescribe some medicine and get an injection...

Veterinarians are not gods, and dogs cannot speak, so they cannot tell the cause of their illness at a glance

The doctor still needs to make further judgment based on blood routine.

Huh? Why do you need to judge this?

Because the pathogens of infection are different, the treatment options are also different

But everyone has seen the blood routine

It’s true, but to determine which infection caused it, we mainly look at three indicators

1. White blood cells

The mission of white blood cells is to phagocytose pathogens and defend against disease.

Its five members, each responsible for their own responsibilities, are the warriors of the animal body fighting against diseases.

If the white blood cell value in the body is higher than normal, it is likely that the body has inflammation.

2. Neutrophils

Neutrophils among white blood cells are born to be scouts.

When there is bacterial invasion in the body, neutrophils will detect it.

Pursue them step by step until the intruder is devoured and destroyed, and they will not stop until they die.

Therefore, elevated blood neutrophils are mostly caused by bacterial infection.

But during viral infection, neutrophils are very helpless.

Because the virus is very small.

The virus will enter the host body,

Neutrophils cannot enter.

3. Lymphocytes

But is this safe?

Lymphocytes expressed dissatisfaction.

Lymphocytes will directly kill infected cells.

Then work with other members to clean up the exposed viruses.

Therefore, the increase in lymphocyte ratio is mostly due to viral infection.

Special reminder:

If there is a fever, your pet also needs to be tested for C-reactive protein.

C-reactive protein is an inflammatory protein secreted by liver cells in the body.

When the body is infected or tissue damaged, the number will increase sharply.

And the quantity is directly proportional to the inflammatory response.

Therefore, doctors sometimes use C-reactive protein as a judgment.

One of the reference standards for whether there is inflammation and the severity of the inflammatory reaction.

In addition, C-reactive protein detected an extremely rapid inflammatory response.

The inflammatory reaction may appear 5-8 hours after it appears.

Now, you should know why dogs need blood tests.

It’s very simple. Without examination, the cause cannot be determined and medicine cannot be prescribed.

Some diseases have a long course, or are recurring or difficult to treat.

It may be necessary to do it again in 2-3 days.

Monitor at any time, there is no way, it is necessary~~~
