What Does The Urinalysis Test Result Mean?

Having healthy kidneys is important for keeping your body healthy. Urinalysis interpretation is summarized in TABLE 1, with the first four tests most commonly evaluated for information leading to the diagnosis of UTI.1 At many institutions, a reflex urine culture is sent if the urine meets set criteria regardless of patient symptoms.
Of the 18 patients with ATN for whom urinary sediment was assessed for outcomes, 61.1% did not recover kidney function and the mean cast scoring index was 2.2. self urine test Patients without renal recovery had a higher cast scoring index as compared with patients who recovered kidney function (2.55 0.93 vs 1.57 0.79; P = 0.04).

The color of the urine is also examined, since color can indicate certain conditions; for example, a red or reddish brown cast in a urine sample is often a sign of hemoglobin or myglobin in the urine (though it can also be caused by some drugs, food coloring additives or even eating fresh beets).
Imaging tests, such as an ultrasound, computed tomography (CT) , or magnetic resonance imaging (MRI) , may be also be used to determine whether the problem is located before the kidneys (pre-renal), in the kidneys (renal), or after the kidneys (post-renal).
A period of dehydration may precede urine collection if testing of renal concentration is desired, but any specific gravity > 1.022 measured in a randomly collected specimen denotes adequate renal concentration so long as there are no abnormal solutes in the urine.

However, routine urinalysis can be effectively used to screen for overt changes such as hematuria, pyuria, glucosuria, bilirubinuria, presence of casts, or abnormal crystalluria, as well as providing general information regarding hydration and concentrating ability (specific gravity or osmolality), acid-base balance (pH), and energy balance (ketones) of the animal at that point in time, as urine samples are often taken at a single time point in a study (e.g., at necropsy, or during the final week of treatment), particularly in rodents.
One to two ounces of urine-a sufficient sample is required for accurate results; sometimes you may be directed to collect a sample using a "clean-catch" technique: women should spread the labia of the vagina and clean from front to back; men should wipe the tip of the penis.
In January, UnitedHealthcare filed a lawsuit seeking $100 million from Next Health, a network of labs, claiming that it had paid doctors bribes as well as kickbacks of 20 percent of revenue for overpriced and medically unnecessary urine and saliva samples.

NOTE: If undergoing medical tests makes you or someone you care for anxious, embarrassed, or even difficult to manage, you might consider reading one or more of the following articles: Coping with Test Pain, Discomfort, and Anxiety, Tips on Blood Testing, Tips to Help Children through Their Medical Tests, and Tips to Help the Elderly through Their Medical Tests.
One of the doctors overseeing Mr. Baker's urinalysis tests was Dr. Michael Ligotti, who was listed as the medical director for nine different treatment centers as of October, according to records kept by the Florida Department of Children and Families.
