What is a 24-hour urine collection?
For some laboratory tests, all urine during a 24-hour period must be collected and added to a large jug, which is provided by the laboratory. It is most important that every drop of urine during the 24 hours be added to the jug, as total volume is used in calculation of the test result. Your physician or the laboratory staff will give you specific instructions about the collection.
A 24-hour urine collection is a simple diagnostic procedure that measures the components of urine. The test is noninvasive (the skin is not pierced), and is used to assess kidney (renal) function. Twenty-four hour urine collection is performed by collecting a person’s urine in a special container over a 24-hour period. The container must be kept cool during this time until it is returned to the lab for analysis. Urine consists of water and dissolved chemicals such as sodium, potassium, urea (formed from protein breakdown), and creatinine (formed from muscle breakdown), along with other chemical compounds. Normally, urine contains specific amounts of these waste products. If these amounts are not within a normal range, or if other substances are present, it may be an indication of a particular disease or condition. The results of a 24- hour urine collection may provide information to help your physician make or confirm a diagnosis. Related procedures that may be used to diagnose kidney
