Normal Results The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day). The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories.

What does low urine output indicate?

Common causes include: Dehydration from not drinking enough fluids and having vomiting, diarrhea, or fever. Total urinary tract blockage, such as from an enlarged prostate. Medicines such as anticholinergics and some antibiotics.

What are the 5 stages of kidney failure?
