• The material for testing is blood.
• The patient does not need to fast. It is recommended to drink a glass of water approximately 30 minutes before the examination.

Factors that may affect test results:
Taking medications, supplements, other substances: sodium salicylate, benzalkonium chloride, dyslipidemia.
Note:
Dehydration, diet, alcohol, intense exercise, or sample collection method may also affect results. Results should be considered in conjunction with other data, such as clinical symptoms, results of other tests, or clinical diagnosis. Interference
from medications or endogenous substances may affect the results.
A detailed list of interfering substances is available from the laboratory upon request (manufacturer's instructions). If in doubt, please contact the laboratory staff.

Sodium (Na) is an important cation in extracellular fluid. It influences acid and electrolyte balance. Abnormal sodium values: vomiting, diarrhea, fever, kidney disease, adrenal cortex disease (Addison's disease), vasopressin deficiency (diabetes insipidus), water and electrolyte imbalance, renal failure, and syndromes associated with polyuria and polydipsia.
Factors that may influence the test result:
Reduced sodium levels may be the result
excessive use of diuretics, prolonging
vomiting, decreased sodium in the diet and metabolic acidosis.
Elevated sodium levels may occur in Cushing's syndrome,
severe dehydration and when consuming large amounts of salt
without sufficient irrigation.

Accredited test. Ordering a test constitutes consent to its performance using the indirect potentiometry method.
