Creatinine (urine)

Urine is collected for the day. The first morning portion in the toilet, all subsequent ones during the day, at night, and the morning portion the next day (for example, from 6:00 a.m. to 6:00 a.m. the next day) are collected in one container, which is stored in a cool place protected from sunlight (at a temperature of 4-8 C).
– it is imperative to indicate the daily volume of urine collected and the volume of fluid consumed per day;
– all collected daily urine is mixed, and 40-50 ml is poured into a separate container and delivered to the laboratory within 2 hours;
– Urine without added preservatives is delivered to the MediLab+ laboratory. Daily urine

Urine is an important biological fluid that is formed in the urinary organs and is excreted from the body through the urinary tract. Urine contains various chemical compounds that reflect the state of the body's functioning. One of these biochemical indicators, which is very important for assessing kidney function, is creatinine.

Creatinine is a product of creatine metabolism, which is mainly formed in muscle tissue. Creatinine is excreted from the body through the kidneys and excreted in the urine. The level of creatinine in the urine can serve as an important indicator of the state of kidney function and the general health of the patient.

Biochemical urine tests to determine creatinine levels help doctors establish a number of important parameters, such as:

1. Kidney Filtration: Measuring the level of creatinine in your urine helps assess how effectively your kidneys are filtering your blood and removing waste from your body. Elevated creatinine levels may indicate decreased kidney function.
2. Diagnosis of kidney diseases: Changes in creatinine levels in urine can be associated with various kidney diseases such as chronic renal failure, glomerulonephritis, kidney infections, etc.
3. Monitoring treatment effectiveness: For patients receiving treatment for kidney disease or other conditions, monitoring urine creatinine levels can be useful in determining treatment effectiveness and adjusting therapy.
4. Checking your overall health: Creatinine can also be an important indicator of a patient's overall health. It can vary due to various factors such as physical activity, diet, and other medical conditions.

A biochemical urinalysis is performed to determine the level of creatinine in the urine. The results of this analysis are expressed in milligrams (mg) per deciliter (dL) of urine. Normally, in healthy individuals, the level of creatinine in the urine is stable and within the established norms.

High levels of creatinine in the urine can be a sign of kidney problems, and may indicate the need for further testing and consultation with a doctor. Doctors may also compare the level of creatinine in the urine to the level of creatinine in the blood to get more accurate information about kidney function.

The general conclusion is that biochemical urine tests, in particular creatinine levels, are an important tool for diagnosing and monitoring kidney function and overall health. These data help doctors identify problems early and develop the optimal treatment strategy for each patient.
