Potassium Test System

FDA 510K for Potassium Test System

A potassium test system measures the amount of potassium in your blood or urine. It can be performed using a blood test or a urine test. Potassium is a vital electrolyte, meaning it carries an electrical charge and plays a critical role in maintaining various functions in the body. These include regulating fluid balance, muscle contractions, nerve signals, and heart function.

Intended Use of Potassium Test System

A potassium test system is a device intended to measure potassium in serum, plasma, and urine. Measurements obtained by this device are used to monitor electrolyte balance in the diagnosis and treatment of diseases characterized by low or high blood potassium levels.

Intended Use:

It is intended to be used for the in vitro quantitative determination of potassium, in heparinized whole blood, heparinized plasma, or serum in a clinical laboratory setting or point-of-care location. Potassium measurements are used in the diagnosis and treatment of renal glomerular or tubular disease, adrenocortical insufficiency, diabetic ketoacidosis, excessive intravenous potassium therapy, sepsis, panhypopituitarism, in vitro hemolysis, hyperaldosteronism, malnutrition, hyperinsulinism, metabolic alkalosis and gastrointestinal loss.

Device Description:

The enzymatic method for potassium testing relies on potassium ions activating specific enzymes, such as potassium-dependent pyruvate kinase. This enzyme catalyzes a reaction that is coupled with other biochemical processes, often producing a measurable signal like a color change or light emission. The intensity of the signal is directly proportional to the potassium concentration in the sample. This signal is then measured using instruments like a spectrophotometer or fluorometer, and the potassium level is determined by comparing the signal to a standard curve. This method is precise due to its reliance on the role of potassium in biological reactions.
