Elektrolyyttipitoisuus

Elektrolyyttipitoisuus, or electrolyte concentration, refers to the amount of electrolytes dissolved in a solution, typically expressed in millimoles per liter (mmol/L). Electrolytes are ions that dissociate in solution, such as sodium (Na+), potassium (K+), chloride (Cl-), and bicarbonate (HCO3-). They play a crucial role in various physiological processes, including nerve and muscle function, acid-base balance, and fluid balance.

The normal range of electrolyte concentrations in the human body is tightly regulated by the kidneys and other organs. For example, the normal range for serum sodium is 135-145 mmol/L, while for potassium, it is 3.5-5.0 mmol/L. Abnormal electrolyte concentrations can lead to various clinical conditions, such as hyponatremia (low sodium), hyperkalemia (high potassium), and metabolic alkalosis (high bicarbonate).

Electrolyte concentration can be measured using various laboratory techniques, such as ion-selective electrodes, flame photometry, and atomic absorption spectroscopy. These measurements are essential for diagnosing and managing electrolyte disorders, which can be life-threatening if left untreated. Maintaining proper electrolyte balance is vital for overall health and well-being.
