Phosphate
Phosphate is a mineral that builds bones together with calcium and is part of energy molecules (ATP) and cell membranes. Its level is regulated by the kidneys, PTH and vitamin D.
| Rating | Range | What it means |
|---|---|---|
| Talk to a doctor | below 0.81 mmol/L | Low phosphate — seek advice. |
| Good | 0.81 – 1.45 mmol/L | Within the reference range. |
| Talk to a doctor | 1.45 mmol/L and above | High phosphate — kidneys/parathyroid glands; seek advice. |
This marker also has 4 age- or sex-specific range sets in the app — the table shows the general one.
Why it matters
An abnormal value points to the kidneys or parathyroid glands.
If it’s low
Low phosphate can cause muscle weakness; causes include poor diet, alcohol, absorption disorders or overactive parathyroid glands.
If it’s high
High phosphate is common with poorer kidney function (not enough is excreted) and can burden the blood vessels and bones.
What to do
Evaluate together with the kidneys, calcium and PTH — these reveal the cause and the action. With kidney disease, phosphate restriction is a medical decision.
