The salt that pairs with sodium, and the other half of the body's main acid-base balance.
Unit mmol/LTypical adult range 98–107 mmol/L
What it is
The salt that pairs with sodium, and the other half of the body's main acid-base balance.
Why it matters
It mostly follows sodium, so the interesting information is in the times it does not.
Reading the number
Read it next to sodium: moving together points at water balance, moving apart points at an acid-base problem. It is rarely informative on its own.
