Urine
Urine pH
How acidic or alkaline your urine is at the moment the sample was passed.
Typical adult range 4.5–8
What it is
How acidic or alkaline your urine is at the moment the sample was passed.
Why it matters
It shapes which kinds of kidney stone can form, and it hints at some urinary infections.
Reading the number
It swings with every meal through the day, so a single value says almost nothing -- diet moves it more than anything medical does. A sample left standing turns alkaline as bacteria grow in it, so an old sample reads high.

When to raise it
