Routine & 24-hour urine collection

What does a 24-hour urine collection entail?

A 24-hour urine collection is a straightforward lab test that determines what’s in your urine. The test is used to check the function of the kidneys. A 24-hour urine collection involves collecting your urine in a special container for the entire 24 hours. Until the urine is returned to the lab, the container must be kept cool.

Urine is composed of water as well as dissolved chemicals such as sodium and potassium. It also has urea in it. This is produced when protein degrades. It also contains creatinine, which is a byproduct of muscle breakdown. Urine normally contains trace amounts of these waste products. If these amounts are not within a normal range, it could be a sign of a disease or condition. Alternatively, if other substances are present.

Why would I require a 24-hour urine collection?

A 24-hour urine collection aids in the diagnosis of kidney problems. It is frequently performed to determine how much creatinine is cleared by the kidneys. It is also used to determine the levels of protein, hormones, minerals, and other chemical compounds.

Conditions that can cause kidney disease include:

  • Diabetic nephropathy.
  • High blood pressure.
  • Lupus nephritis.
  • Frequent urinary tract infections.
  • Prolonged urinary tract blockage.
  • Alport syndrome.
  • Nephrotic syndrome.
  • Polycystic kidney disease.
  • Interstitial nephritis or pyelonephritis.
  • Screening for preeclampsia in pregnancy.
  • Kidney stones (nephrolithiasis)

There may be other reasons for your healthcare provider to recommend 24-hour urine collection.
