The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more
What about it?: 24 hour urine collection for protein is one test for renal disease. To accurately collect the specimen, go pee in the bathroom at a given time in the morning, say 8 am. Then all day pee in the jug given to you and the following morning pee in the jug at 8 am whether you feel like peeing or not. That would ensure accurate 24 hour specimen. ...Read more

Two different things: Clean midstream catch is a term used for obtaining urine that is after the stream has started. It's usually a one time catch, or serial one time catches. The 24 hour urine sample requires you to collect all urine and 24 hours. That's used to determine how much of a substance has been peed out over 24 hours, and dividing it by the milligrams that was collected from what was ingested. ...Read more
How likely do I have wilson's disease if I have a low ceruloplasmin and high copper on 24 hour urine?
They can't detect copper in my urine after two 24 hour urine tests. What can this indicate. My blood copper is rite on the normal mark and my cerulospasmin is a little low ..I am a 25 year old male.
Why do you ask?: If you are being screened for wilson's disease, finding no copper in your urine is good news. If none's detectable, the physician needs to call the pathologist in charge of the lab and ask why -- there's a problem. Healthy blood copper actually covers a considerable range (no 'mark'), and ceruloplasmin 'a little low' is only one item in a big picture. ...Read moreSee 1 more doctor answer
Tell kidney function: Single urine specimens can be tested for creatinine. But daily urine output and urinary concentration varies hence a 24 hr urine collection. Normal creatinine output for an adult should be >1gm/24 hours. Also getting blood creatinine provides optimal way to accurately determine creatine clearance which in turn is a most accurate way to measure kidney function. ...Read moreSee 1 more doctor answer
Diagnostic test: 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. Specifically the amount of creatinine excreted is measured to get an estimate of the glomerular filtration rate (gfr). ...Read moreSee 1 more doctor answer
Likely no problem.: Your creatinine is within normal range (< 1.5 mg/dl). Normal ranges can vary, but this is well within many. Your 24 urine was normal, which likely means your kidneys are working properly and you likely don't have any diseases, like diabetes, etc. That cause abnormal amounts of urine to be produced. ...Read more
Good question: The creatinine is used to assess the quality of the collection. Based on your weight, body composition, and being a female you should have a certain amount of creatinine in your collection. If the amount in the specimen is above or below this amount, then it helps the physician to determine the collection was really 24hrs worth. ...Read more
Different chemicals: A 24 urine is not a test per se. Many chemicals in urine need to be measured over a period of 24 hours.

24 hour urine catecholamine for a pheo- if a person does not have an episode during the 24 hours would it still show elevated levels. If so how?
Usually, yes: A pheo usually secretes catecholamines continuously, so it is not usually necessary to time the collection. These catecholamines yield a lot of breakdown products (eg. metanephrines). However, in some circumstances, if there is a very high suspicion for pheo and the initial tests are negative, and the attacks are sporadic, a urine collection timed with the episode is reasonable. ...Read more
