Phosphate (Phosphorus)

Vitamins & Minerals

A healthy result should fall into the range 2.5 - 4.5 mg/dL, or 2.50 - 4.50 mmol/L.

Along with calcium, sodium, potassium, magnesium and chloride, phosphorus is one of the six essential minerals required by the human body in significant quantities.

Phosphate concentration is characterized by a high physiological variation, depending on age, gender, physiological state (eg, pregnancy), and even season (due to the seasonal variation of vitamin D which is directly involved in the regulation of phosphate concentration).

Therefore, separate reference intervals have been established according to the age and gender:

In males, the reference range is as follows:

Age 0-12 months - Not established

Age 1-4 years - 4.3-5.4 mg/dL

Age 5-13 years - 3.7-5.4 mg/dL

Age 14-15 years - 3.5-5.3 mg/dL

Age 16-17 years - 3.1-4.7 mg/dL

Age 18 years or older - 2.5-4.5 mg/dL

In females, the reference range is as follows:

Age 0-12 months - Not established

Age 1-7 years - 4.3-5.4 mg/dL

Age 8-13 years - 4-5.2 mg/dL

Age 14-15 years - 3.5-4.9 mg/dL

Age 16-17 years - 3.1-4.7 mg/dL

Age 18 years or older - 2.5-4.5 mg/dL

What does it mean if your Phosphate (Phosphorus) result is too low?

- Alcoholism

- Hypercalcemia (too much calcium in the body)

- Hyperparathyroidism (parathyroid glands make too much of their hormone)

- Too little dietary intake of phosphate

- Very poor nutrition

- Too little vitamin D, resulting in bone problems such as rickets (childhood) or osteomalacia (adult)

What does it mean if your Phosphate (Phosphorus) result is too high?

- A higher than normal level (hyperphosphatemia) may be due to many different health conditions. Common causes include:

- Diabetic ketoacidosis (life-threatening condition that may occur in people with diabetes)

- Hypoparathyroidism (parathyroid glands do not make enough of their hormone)

- Kidney failure

- Liver disease

- Too much vitamin D

- Too much phosphate in your diet

- Use of certain medicines such as laxatives that have phosphate in them
