Odor is not normally recorded in a urinalysis, but some characteristic odors may indicate certain conditions. A fresh urine specimen has a slight aroma. Alkaline fermentation causes an ammoniacal odor when standing in the open air.
Dehydration causes your urine to be more concentrated which is also a contributing factor to a stronger smell of ammonia in your urine. Another cause for an ammonia-like odor in urine is bacterial infection (especially in women due to their anatomy), including kidney, urinary tract or urinary bladder infection.
Women often complain of an ammoniacal odor in their urine in pregnancy. This can be a sign that you are not drinking enough water.
Fruity-smelling urine may be caused by prolonged fasting or diabetes.
The odor of your urine may be changed by some foods, such as asparagus, and medications (B6 vitamins, ampicillin, amoxicillin, omnipen, ciprofloxacin, proloprim, trovan, etc.)
