What are the normal values for CR in medical terms?

Update Date: 2024-06-04 Source: Network

CR refers to blood creatinine, with a normal range of 88-176μmol/L. If there are abnormalities, further examination should be carried out to identify the causes and provide targeted treatment.

I. Normal Medical Values of CR

Blood Cr refers to blood creatinine, with a normal range of 88-176μmol/L. Blood creatinine is a metabolite of creatine in the human body. Elevated blood creatinine levels are commonly seen in decreased glomerular filtration function caused by various reasons, such as acute renal failure. During acute renal failure, blood creatinine levels will increase significantly and progressively, which is one of the markers of acute renal injury. Additionally, chronic renal failure can also lead to a significant increase in blood creatinine levels. Through blood creatinine testing, it can also be determined whether the patient has pre-renal oliguria or renal parenchymal oliguria. When there is organic renal failure, creatinine levels often exceed 200μmol/L. However, in cases of pre-renal oliguria caused by factors such as dehydration, heart failure, nephrotic syndrome, etc., the concentration of creatinine generally does not exceed 200μmol/L.

II. What to Do When CR Levels Are High

1. Treatment through Diet: The principle of using diet to treat elevated creatinine lies in strengthening kidney function. When kidney function is strengthened, the creatinine level in the body will naturally improve. Therefore, in terms of diet, it is necessary to achieve a low-protein and low-phosphorus diet as much as possible. The purpose of this is to prevent the accumulation of metabolic waste in the body, which can increase the burden on kidney function. Additionally, they can reduce the breakdown of protein in the body and provide a certain amount of heat to the body.

2. Treatment of High Blood Pressure to Slow Disease Progression: A significant cause of elevated creatinine levels is high blood pressure. Therefore, if it can be confirmed that the cause of elevated creatinine is high blood pressure, controlling blood pressure can help delay disease progression and reduce creatinine levels in the body. Therefore, treatment of hypertension can be used to slow the progression of the disease.

3. Drinking More Water to Change the Consistency of Blood: When the body lacks water, the concentration of blood will increase. As the concentration of blood rises, it can lead to an increase in creatinine. Therefore, when a patient has been diagnosed with a cause related to dehydration, drinking a large amount of water can help dilute the concentration of blood and thereby improve creatinine levels in the body.

4. Increasing Iron and Folic Acid Intake to Improve Anemia: When a patient has anemia, it can also lead to an increase in creatinine levels in the body. In this case, the patient can improve anemia symptoms by increasing iron intake and appropriately increasing folate intake. If the patient's anemia is severe, erythropoietin can be used under the professional advice of a doctor. When the number of red blood cells in the body reaches a normal level, the creatinine level will naturally return to normal.
