Cardiological risk assessment

About the parameter

Please double-click for fullscreen

Potassium is the most important cation in the intracellular liquid. It represents a crucial buffer within the cell. Potassium facilitates nerve conduction as well as muscle function and maintains the osmotic pressure. Abnormal potassium levels influence the breathing muscle stimulation and heart muscle function.

Elevated potassium levels (hyperkalaemia) occur with kidney insufficiency, urinary tract obstruction, respiratory or metabolic acidosis and hypoadrenocorticism, as well as excessive haemolysis in cats, horses, cattle and several dog breeds.

Usually, reduced potassium levels (hypokalaemia) are the result of excessive salt loss caused by severe diarrhea or regurgitation.

Low potassium values on the other hand correlate with insufficient food intake (anorexia, especially in cats), malabsorption and severe burns.



This is an immunoturbidimetric test. The reagent agglutinates potassium ions and forms a stable, cloudy suspension. The degree of turbidity is measured by the photometer at 546 nm.

Sample material

A sample of 20 ┬Ál fresh serum or lithium-heparin plasma is needed. Haemolytic or lipaemic samples must never be used!

Test duration

The test duration is under 4 minutes.

Measurement range

0 – 12 mmol/l
