How are the causes of changes in urine diagnosed?
If you have changes in the color, odor, or consistency of your urine that last more than a few days and do not seem tied to any diet or medicine changes, you should contact your healthcare provider.
Your doctor will most likely begin your appointment by asking you to describe the changes. This includes asking about how long you have had these changes and whether you have seen any blood in your urine. The doctor will also ask about any dietary or medicine changes and how much water or liquids you are drinking. He or she will also ask if you are feeling pain when urinating or have pain in your abdomen or bladder area. You may also be asked about any appetite or thirst changes. These questions will help determine if an underlying condition could be causing the changes in your urine. If the doctor remains concerned that something abnormal is going on, a urine sample may be taken. This sample will be tested. The test looks for blood, protein, inflammation (urinalysis), and possibly bacteria that could be causing an infection (urine culture) if a UTI is suspected.
A blood test may also be taken to check for possible kidney damage, diabetes, or a buildup of liver enzymes.
