What is creatinine in the blood


Biochemical blood analysis allows not only to get an idea of ​​the work of an organ in the human body, but also to determine the lack or, conversely, an excess of various components in the blood. One of these components is creatinine.

Creatinine is a substance that is a product of muscle metabolism. Creatinine is eliminated from the body along with urine, therefore, by the amount of this substance in the human body, it is possible to judge the quality of the functioning of the kidneys. The determination of the level of creatinine is of great importance for the timely detection of various pathologies of the urinary system, including kidney failure.

Creatinine in the blood: normal

What is the rate of creatinine in the blood? An unequivocal answer to this question is impossible. In men and women, this figure varies somewhat. This is due to the fact that men tend to have more muscle mass. Consequently, their creatinine level is higher than that of women. So, for boys and men, the rate is 62-116 µmol / l, while for women it is the norm of 54-97 µmol / l.

As for children, the rate for newborns is 22-35 µmol / l, for children from 1 year to 14 years, the index ranges from 28 to 68 µmol / l.

These figures are not constant and may vary depending on the age and degree of physical fitness of the person. For example, in elderly people, the level of creatinine in the blood may be lower than generally accepted indicators, while in athletes and bodybuilders, on the contrary, it will go off scale.

How to determine creatinine level?

Creatinine level is determined using a biochemical blood test. To obtain the most accurate result and, as a consequence, the correct diagnosis, the procedure should be carried out on an empty stomach in the morning. From the time of the last meal, you must have passed at least 9 hours. Otherwise, the analysis may not reflect the real state of affairs.

Elevated levels of creatinine in the blood may indicate serious health problems. Such as chronic and acute renal failure, hyperthyroidism (increased activity of the thyroid gland) or muscle damage.

It should be remembered that creatinine is significantly increased in athletes and people who have a lot of meat in their diet. In addition, this substance may exceed the norm in girls and women who adhere to low-carb diets, the basic principle of which is the rejection of carbohydrates in favor of protein foods. These diets include the Atkins diet, Dukanai and others.

Some medications may also affect creatinine levels. For example, antibiotics of a number of tetracyclines and cephalosporins, as well as anti-inflammatory and antipyretic drugs such as diclofenac, ibuprofen, etc.

Instead, it is recommended to eat more cereals (especially buckwheat), as well as vegetables and fruits (pumpkin, pomegranates, tomatoes and citrus). Such a diet will help slow the process of creatinine production and, as a result, reduce its level in the blood.
