PHOS | Phosphorus

Phosphorus – is one of the most important minerals in the body, forming the structure of bones and teeth. It is essential for the formation of DNA and RNA, participates in energy production, the maintenance of acid-base balance, and metabolic processes. Phosphorus is also important for the absorption of calcium and vitamin D and for faster healing of bone fractures. Nursing women need phosphorus for milk production.

The level of phosphorus in the blood is closely related to calcium metabolism. Its concentration increases with calcium deficiency, vitamin D overdose, or kidney dysfunction. Reduced phosphorus concentration can be observed during menstruation, at the end of the day, and also during winter due to seasonal fluctuations.

Study principle: Phosphorus levels in the blood are determined by biochemical methods from venous blood. Results are usually presented in mmol/l units. When evaluating results, it is important to consider calcium, vitamin D, and kidney function indicators.

Recommendations:

• It is recommended to perform it prophylactically once a year.
• Useful for evaluating calcium and vitamin D metabolism.
• The test is prescribed when suspecting metabolic disorders, bone diseases, or kidney dysfunction.
• Performed on patients after fractures, especially if healing is prolonged.
• Diet, supplements, physical activity, and time of day can influence test results.
• It is recommended to arrive for the test fasting for at least 12 hours.
