Urine potassium

Urine potassium refers to the determination of potassium concentration in urine for 24 hours. The excretion of urinary potassium is closely related to the diet and the level of potassium in the body. Urine potassium determination can reflect the condition of kidney disease. Potassium is one of the major cations in the cell. The human body consumes potassium through the diet, and the kidneys are balanced according to the needs of the body, such as the function of maintaining sodium and discharging potassium, maintaining water, electrolyte and acid-base balance. Urine potassium is higher in the evening than in the daytime, so it is necessary to collect all the urine for 24 hours to accurately reflect the level of urinary potassium. Basic Information Specialist classification: growth and development check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in Addison's disease, acidosis, chronic renal failure, chronic interstitial nephritis, adrenal crisis, bilateral adrenalectomy. Normal value: Urine potassium (ion selective electrode method): 25-100mmol/24h Above normal: Found in primary aldosteronism, Cushing's syndrome, acute renal failure, polyuria, renal tubular acidosis, diabetic ketoacidosis, alkalosis, early starvation. negative: Positive: Tips: Do not exercise vigorously, maintain a good diet and work. The middle part of the urine is taken for inspection. Women in the menstrual period are not suitable for this examination. Normal value Ion selective electrode method: 25 ~ 100mmol / 24h. Clinical significance Reduced in Edison's disease, acidosis, chronic renal failure, chronic interstitial nephritis, adrenal crisis, bilateral adrenalectomy. Increased in primary aldosteronism, Cushing's syndrome, acute renal failure, polyuria, renal tubular acidosis, diabetic ketoacidosis, alkalosis, early starvation. High results may be diseases: pediatric Barth Syndrome, periodic paralysis, pediatric periodic hypokalemia, pediatric total distal renal tubular acidosis, renal magnesium loss, Liddell syndrome, hypertension in the elderly, low Potassiumemia, hyperkalemia, hypokalemia in the elderly Before the test: prohibit strenuous exercise, maintain a good diet and work schedule, stop the licorice, raw stomach ketone, amphetamine, amphotericin B, barbital and other drugs one week before the test. Drink alcohol for 3 days before the test. At the time of examination: a part of the urine is discharged first to wash away the bacteria remaining in the urethra and the anterior urethra, and then the middle part of the urine is taken for inspection. Inspection process The urine of the subject was collected and detected by chemical methods. Not suitable for the crowd Not suitable for the crowd: women in the menstrual period, cold patients. Adverse reactions and risks No.
