Phosphorus (P), Serum
The test determines the phosphorus level — an important macroelement involved in bone tissue formation, energy metabolism (ATP), and muscle and nervous system function. Used for diagnosing phosphorus metabolism disorders, monitoring bone, kidney, and endocrine system diseases.
Mechanism of abnormalities: decreased phosphorus level may indicate deficiency, absorption disorder, or increased urinary loss. Elevation may be related to kidney function disorder, vitamin D excess, or metabolic disorders.
Recommended for:
- people with chronic kidney diseases
- with bone metabolism disorders
- for monitoring metabolic and endocrine disorders
- with suspected phosphorus deficiency or excess
Biomaterial: Venous blood
- Submit fasting (8-12 hours without food)
- Do not drink water
- Avoid phosphorus-rich foods, alcohol, and intense physical exertion for 24 hours
Medications: if taking phosphorus supplements or calcium/vitamin D medications — inform the doctor
- Suspected bone metabolism disorders (osteoporosis, rickets)
- Kidney diseases
- Metabolic disorders (related to calcium and vitamin D)
Monitoring therapy in chronic kidney diseases or endocrine disorders
Normal — serum phosphorus level within reference values
Abnormality — requires physician assessment to determine the cause of change and prescribe correct treatment
Which doctor to consult:
For test abnormalities, consultation with a general practitioner or endocrinologist is recommended. The doctor evaluates laboratory results, correlates them with the clinical picture, and if needed prescribes therapy or additional examinations.
Self-treatment is not recommended!
