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

Phosphorus is one of the important chemical substances present in the human body. It performs numerous functions, and one of them is participation in biochemical processes associated with the formation and excretion of urine. Biochemical studies of urine play an important role in assessing human health and diagnosing various diseases. In this article, we will consider the role of phosphorus in biochemical processes of urine and methods for studying this parameter.

Phosphorus is a macroelement that is important for the vital activity of the body. It is a part of nucleic acids, phospholipids, phosphoproteins and other biologically active compounds. One of the main sources of phosphorus in the body is food products such as meat, fish, milk, eggs and many others. Phosphorus is used to build DNA and RNA, phospholipid cell membranes, as well as to regulate acid-base balance in the body.

During the process of phosphorus metabolism in the body, urine is formed, which is an important biological fluid and a means of eliminating excess phosphorus. The value of phosphorus in urine can be an important indicator of health. Changes in the level of phosphorus in urine can be associated with various diseases and metabolic disorders.

Phosphorus in urine can be measured using various biochemical methods. One of the most common methods is spectrophotometry. This method is based on measuring the absorption of light by a urine sample at a specific wavelength. The results are expressed in micromoles of phosphorus per milliliter of urine.

Changes in urinary phosphorus levels can be indicators of various diseases. For example, hyperphosphaturia (increased urinary phosphorus levels) can indicate conditions such as hyperparathyroidism, chronic renal failure, diabetes, acidosis, and others. In contrast, hypophosphaturia (decreased urinary phosphorus levels) can be associated with various bone diseases, metabolic disorders, and other conditions.

To correctly interpret the results of urine phosphorus tests, it is important to consider other clinical and biochemical parameters. It is also necessary to consider factors that can affect the level of urine phosphorus, such as nutrition, physical activity, medication, etc.

In conclusion, urinary phosphorus plays an important role in the biochemical processes of the body and can be an informative indicator of health status. The study of urinary phosphorus levels is an important part of clinical analysis and can be useful for the diagnosis and monitoring of diseases related to phosphorus metabolism.
