Phosphate
The mineral that pairs with calcium in bone, and that every cell uses to carry energy around.
Unit mg/dLTypical adult range 2.5–4.5 mg/dL
What it is
The mineral that pairs with calcium in bone, and that every cell uses to carry energy around.
Why it matters
It moves opposite to parathyroid hormone, so reading it with calcium and PTH is what makes any of the three interpretable.
Reading the number
It is highest in the late evening and lowest in the morning, so compare draws taken at the same time of day. It falls after a carbohydrate-heavy meal as phosphate moves into cells.

When to raise it
Worth reading with calcium and PTH rather than on its own.
