Measures

Potassium in serum.

Why it matters

Potassium is essential for nerve signalling and muscle contraction, including cardiac muscle. The body holds it within a narrow range.

Before you collect

Sample handling genuinely matters here — potassium leaks from red cells if a sample is difficult to draw or delayed in processing, which can produce a falsely raised result. A surprising potassium result is often a collection artefact and worth repeating before acting on.
