Why Would A Doctor Order A 24 Hour Urine For Catecholamines Test
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

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

Should i contact a different doctor for adrenal mass went to a urologist after a CT scan for kidney stones showed an adrenal mass. Urologist sent me for a MRI and had me do a 24 hour urine test to see why i had kidney stones. I am more worried about the
The most common: Adrenal mass seen in about 15% of patients is an adrenal adenoma which is a benign tumor. It is easy to characterize on MRI because we can show there is fat in the tumor. This usually (94% accurate) means that the adrenal tumor is benign. But we make sure by following the tumor with additional MRI studies, which do not use harmful radiation. Ultrasound is not as accurate for followup. ...Read moreSee 2 more doctor answers

Tough to say: Since your Urine test was negative for pregnancy that does not bode well for being pregnant. You need to follow-up with the Doctor and get a serum test to confirm if need be and even serial testing of Quantitative B-HCG to see if the number is going down or up, etc. Best wishes to you. ...Read more
Microalbumin numbers and type 2 diabetes type 2 diabetes diagnosed 1 1/2 years ago. I did a 24 hour test and my microalbumin 24 tv results came back 2, 390, (extremely high), but my urine microalbumin/24hr came back at 12.0. My doctor sent me the test r
These : These two results sound at first hearing very different. The last 24 hour result is normal. Keep in mind that the spot (random) urine is evaluated as a ratio urine microalbumin to as miligrams of Albumin per gram of creatinine or micrograms Albumin per milligrams of creatinine. A spot determination is as good as the 24 hour collection, in general, so we do not recommend doing 24 hour collections. They are a nuisance. After less than 2 years of diabetes you would not be expected to have diabetic kidney disease. There may be a lab issue problem. Normal 24 hour urine Albumin is less than 30 milligrams. Was that first collection expressed as 2390 milligrams or micrograms? If micrograms, that value is not high. See a nephrologist if there is a question. And get a simple urinalysis to check out other aspects of your urine. ...Read more
