General Information

Potassium The largest amount is excreted by the kidneys; K + excretion depends on the amount of potassium taken. At the nephron level, potassium undergoes three main mechanisms: glomerular filtration, complete reabsorption in the proximal tubules, and secretion in the distal tubules. Potassium excretion depends exclusively on filtration and secretion processes.

When should we take the test?

Examination of water-saline and acid-base balance in renal and adrenal disorders;
Differential diagnostics of hypo- and hyperkalemia.

Possible interpretation of the results

The concentration of potassium in the urine increases:

Enhanced excretion of K + associated with hypokalemia (K + in urine> 20 mmol / L)

K + loss by the kidneys during kidney disease.
Diuretics.
Renal tubular acidosis type I and II;
Diabetic or alcoholic ketoacidosis;
Primary and secondary hyperaldosteronism;
Cushing's syndrome;
Barter syndrome;
Metabolic alkalosis due to intestinal loss of HCl (vomiting, gastric drainage).

Enhanced excretion of K + associated with hyperkalemia (K + in urine> 40 mmol / L)

Intake of large amounts of potassium (with food or through therapy);
Reduction of K + penetration into cells: Insulin deficiency, introduction of β-blockers, digitalis.
Tissue destruction, hemolysis;
Metabolic acidosis;
Infusion of hypertonic saline solution.

The concentration of potassium in the urine decreases:

Decreased excretion of K + associated with hypokalemia (K + in urine <20 mmol / L)

Decrease in K + intake;
Extrarenal loss of potassium (skin, fistulas, laxatives, diarrhea).

Decreased excretion of K + associated with hyperkalemia (K + in urine <40 mmol / L)

Hypoaldosteronism and pseudohypoaldosteronism;
Kidney disease with low urine flow (nephrosclerosis, pyelonephritis, glomerulonephritis).

Product description

Metabolic alkalosis is the most common manifestation of potassium loss. Loss of potassium by the kidneys occurs in several cases:

Excess amounts of mineralocorticoid hormones;
Renal tubular lesions;
Reloading of tubular fluid with Na +;
Alkalosis.

In acute renal failure, potassium is not filtered glomerularly and is not excreted in sufficient quantities through the tubes. Extrarenal dialysis is the safest way to correct potassium levels in all patients with severe hyperkalemia.

Study material / urine collection rule

24-hour urine. At 7 o'clock in the morning the patient urinates and does not store this urine, and during the next urination he collects the whole volume of urine in a plastic container (2-3 liter urine container) until 7 o'clock in the morning of the next day (24 hours); The patient should transfer 100 ml of urine from this container (e.g. with a syringe) to a disposable plastic cup for urine and should be stored at 2-8 ° C before the test (1-1,5 h).
