What does a low result mean?

A slightly low level is often linked to drinking very large amounts of plain water or mild diuretic therapy.

What does a high result mean?

A mild elevation primarily indicates minor water deficit or unreplenished sweating following exercise.

Questions ready for your doctor

Bring these questions to your next consultation to discuss with your healthcare practitioner:

  • Could this reflect my recent fluid intake patterns?
  • Might any current medication (such as a diuretic) be involved?
  • Should I adjust my daily water or sodium consumption?
