Blood is a bright red liquid that fills blood vessels. In addition to blood cells, blood also contains many different substances. Detecting the contents of various ions, sugars, lipids, proteins, various enzymes, hormones and various metabolites of the body in the blood is called blood biochemical examination. It can provide doctors with a basis for diagnosis and treatment, and can help clinical patients determine the condition and monitor treatment effects.

This laboratory test is different from the usual blood routine. It does not involve cellular components in the blood. It only detects various enzymes and metabolites in plasma or serum other than cells to determine the specific functional status of the body's tissues and organs. . However, this test often requires many items to be tested at the same time for comprehensive judgment, so the cost is relatively high, and it is an inspection that is rejected more frequently. ​​​​​​

First, let’s take a look at the specific content of the biochemical examination. The first is the serum protein examination. The normal value of total protein is 65--85g/L. The normal value of albumin is 35--55g/L. The clinical significance is that it can understand the general situation of protein metabolism in the body, and has certain diagnostic and differential diagnosis significance for liver and kidney damage, multiple myeloma, etc. It also has certain diagnostic and differential diagnosis significance for liver and kidney damage and multiple myeloma. The normal value of transferrin (Tf) is 0.03--0.4μmol/l. Its elevation indicates pregnancy, iron deficiency anemia, and acute hepatitis. If it decreases, it may be caused by liver and kidney disease, thyroid disease, etc.

The second is the measurement of bilirubin. The normal value of serum total bilirubin is 1.7--17.1 μmol/L. It is of great significance for the diagnosis and differential diagnosis of jaundice types. The normal value of serum direct bilirubin is 0.3--3.4μmol/L. It is of great significance for the diagnosis and differential diagnosis of jaundice types. Next is the measurement of some enzymes. The normal value of alanine aminotransferase (ALT) is 20--40μ. It is of great significance for the diagnosis of myocardial infarction and liver parenchymal lesions and the observation of disease changes. The normal value of gate glutamine transaminase (AST) is 40μ. It is elevated during acute myocardial infarction, and often increases during liver disease and inflammation of other organs. The normal value of r--glutamyl transferase or transphthalase (r--GT) is 6--47μ/ml. It is significantly increased in hepatobiliary system lesions, especially liver cancer. The normal value of creatine phosphokinase (CK) is 5.5--75IU/L. It is significantly increased in skeletal muscle diseases, hypothyroidism, and acute myocardial infarction. The normal value of lactate dehydrogenase (LDH) is 150--450μ. It is significantly increased during acute damage to the heart, liver, lungs and other tissues.

Finally, there is the measurement of some inorganic salts. The normal value of potassium is 3.5--5.3mmol/L. The clinical significance is to determine electrolyte and acid-base balance. The normal value of sodium is 136--145mmol/L. It can determine electrolyte and acid-base balance. The normal value of chlorine is 100--106mmol/L. Mainly to determine the electrolyte and acid-base balance. The normal value of calcium is 2.2--2.7mmol/L. It can determine parathyroid function, vitamin D deficiency, bone tumors, and multiple myeloma. The normal value of inorganic phosphorus is 1.0--1.6mmol/L. The clinical significance is to determine parathyroid function, vitamin D deficiency, bone tumors, and multiple myeloma. The normal values ​​of magnesium and iron are 0.8--1.2mmol/L and 11--27pmol/L respectively. It is of certain significance to determine renal function, dehydration, hyperthyroidism, digitalis poisoning, etc. and to identify various anemias.

So why do we need to do a blood routine on cats? Is it necessary? We know that the body operation of pets, drug metabolism and normal elimination of metabolic wastes all depend on normal tissue and organ functions. However, it is impossible for us to detect abnormal conditions of organs by only relying on thermometers, stethoscopes, sight and touch, especially the liver and kidneys, which are particularly important for body metabolism. Observing your pet's status and combining its performance can infer its general organ function, but please note that it is speculation! Yes, it is speculation. Everything is based on the subjective speculation of doctors. Do you think it is reliable? In everything If you don’t know anything about it, try to speculate. Is it more likely to be a chance of luck... I once met a vomiting and very depressed cat who came to the pet hospital for treatment. We asked the owner to test the liver and kidney function to check the specific conditions. The possible cause of the disease and the specific functional status of the body, but its owner said like many people: "My cat is just vomiting, you can just stop the vomiting, don't do these troublesome tests!" But the cat vomited the next day. Although he stopped, he was still in low spirits. After our repeated explanations and persistence, the owner reluctantly agreed to conduct a liver and kidney function test. The result was that the cat’s kidney function indicators were surprisingly abnormal, showing signs of acute renal failure. Fortunately, the cat’s kidney function indicators were surprisingly abnormal. The best thing is that we discovered this before it was too late. After targeted treatment, the cat basically recovered in about half a month. We really can’t imagine what would happen if there had been no inspection.

Especially for babies who have entered old age or pets that have undergone long-term treatment, due to the natural decline of organ function or the impact of disease, the function of their liver or kidneys is often weakened to a certain extent. Medication without specific changes often leads to excessive liver and kidney damage due to slowed excretion of the drug or damage to the drug. Especially before surgery, if anesthesia is blindly carried out without understanding the liver and kidney functions, it will often lead to too deep anesthesia or too long anesthesia recovery time, and sometimes even cause immeasurable losses.
