What causes low specific gravity?
Very low specific gravity means dilute urine, which may be caused by drinking too much fluid, severe kidney disease, or the use of diuretics.
Does low specific gravity mean dehydration?
To put it another way, the specific density of water would be 1.000. Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.
What is urochrome in urine?
