Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. 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
Why when doing a 24hr urine test do u have 2 collect every drop, why does it matter if you lose a little of the urine? How does it change the results
24 hour urine: The short answer is because what your doctor is basing his/her decision on is based upon what shows up in your urine in 24 hours. Norms have been established based upon the 24 hour time frame. Missing even a small volume can throw off the results if what is being looked for comes in small quatities in the urine already. Best to be thorough and complete. ...Read moreSee 1 more doctor answer
What should be done to avoid having poteins in the urine after 24hr urine collection, does medicines render the amount back to normal to below 30mg?
Proteinuria: Proteinuria (p) is a sign of kidney disease, not a diagnosis. P may be caused by a disease of the kidneys called glomerulonephritis (g) and other times it may caused by diabetic kidney disease. Go and see a nephrologist to have some blood tests ordered to see if the cause of your p can be found and then treated. If your p is due to diabetes, medicines such as ace-inhibitors an arb's can lower p. ...Read more

When collecting 24hr urine for hormone testing, if fmv on day 2 occurs more than 24hrs after fmv on day 1 (discarded), shall i collect day 2 fmv?
24 hour's worth: The goal is get just 24 hours of urine. That means if one urinated into the toilet first, and then started collecting after that time, she should collect the last sample before the clock hits 24 hours. If it hits 24 hours around dawn, she will want to collect that first morning void to get all that nighttime urine. If that fmv is at hour 25-26, i would collect it and tell the doctor what happened. ...Read more

How high is this?n Low Ceruloplasmin, is this Wilson disez? coper 76 norm
Not Wilson's: Urine copper is very high in Wilson's. I'm going to assume that your urine copper was 12 mcg/24 hours. You're very right to be concerned about Wilson's -- it's among the most treacherous of all diagnoses. Reference ranges are set so that a few percent of healthies fall outside on either end. In Wilson's, your urinary copper is often 1000's. Best wishes. ...Read more

24hr urine test cortisol was 51nmol, creatinine 5.8nmol(low)I was exactly 10mins shy of being at 24hrs.When creatinine tested in feb Was 7. What is it?
24 hr urine: Your urine creatinine will vary. Beside kidney function, exercise, muscle damage/bruising, meat intake and other factors can affect this. It is hard to interpret the numbers you give, since it is not clear what the normal range is, and whether the values are normalized to urine volume. Talk to your doctor. ...Read more
24hr urine (5000mL) creatinine, protein, and albumin results are high - about double the max normal, but blood is normal. What would cause this?
Proteinuria: With certain kidney pathology there can be heavy amounts of protein lost in the urine due to glomerular pathology but the rest of the kidney function can be good enough so that blood tests for kidney function are still normal. A nephrologist can better explain your status after evaluating you and all your pertinent test results. ...Read more
If normethanephrine free 181pg/ml & metanephrine free 232 pg/ml 24hr urine collection, will my sister's matanephrine fractionated blood work be bad?
My pcp today said my results were normal from my urinalysis & 24hr urine collection. How did numbers go normal from 2007, my GFR used to be around 58?
Time to talk: Frankly with your dr. Estimating the GFR in clinically healthy people based on spot bloodwork (not urine) is a fad that many pathologists and nephrologists consider unscientific and unfortunate. (the correction "because black people are more muscular" is one sign of subscience.) well-muscled men end up as kidney cases when they're really not. Urinalysis isn't even used for gfr. ...Read moreSee 1 more doctor answer

Should I avoid having sex or masturbating while completing a 24hr urine test? Will those bodily fluids show up in urine collection?
I have a small adrenal nodule. My basic metabolic blood test was fine. Yay. Does that mean my cortisol 24hr urine collection will be to?
Here are some...: A small adrenal nodule seemed found incidentally and usually non-functioning benign adenoma, which deserves a wait, watch, & see by repeating another imaging study - US or CT - in 6-12 months with a timely clinical follow-up afterward, as long as metabolic tests are ok and BP is easily under control with adequate general well-being. Of course, if still in doubt, ask your doctor who ordered test ...Read more
24hr urine test show 3.5 mg on hydroyindindoleacetate but 2l, 00 on chromogranin a is this normal, or does it show possible carcinoid tumor?
Normal: A chromogranin a level of 21 is normal is most labs, as is a hiaa level of 3.5. Elevated chromogranin a levels are non specific, and can be high for many different reasons, many of which have nothing to do with tumors. The test tends to be more helpful, when normal, for decreasing the risk of having a neuroendocrine tumor. ...Read more
