What is Urine Alcohol Test?

A urine alcohol test is one of the most common medical tests. It involves laboratory examination of a urine sample to measure its components and characteristics.

A routine urine test may measure the following:

pH: This measurement indicates the acid/alkaline balance of the urine. Abnormal pH levels may indicate the presence of kidney disease, urinary tract infection, or excessive aspirin use.

Color: Normal urine ranges from pale yellow to amber, but it may be darker due to dehydration, which makes the urine more concentrated. Dark urine may also be the result of a buildup of bile pigments, due to liver or gall-bladder disease.

Specific Gravity: This measurement evaluates the ratio of water to other substances in the urine. An abnormal concentration may indicate dehydration.

Protein: This indicates abnormal kidney function, for example, due to nephritis (a group of diseases usually involving inflammation of the kidneys) or damage from diabetes or high blood pressure.

Ketones: These are substances produced by the incomplete breakdown of fat in the body and may indicate poorly controlled diabetes, dehydration, starvation, high fever, or overuse of aspirin.

Blood: This may indicate infection, kidney disease, or urinary tract injury, but it may simply be derived from menstruation.

Bacteria: These indicate a urinary tract infection.

Glucose: This indicates either diabetes or altered kidney function.

Cells: The urine sediment normally contains a few white blood cells. Infection, or injuries of the urinary tract, can greatly increase the number. Similarly, excessive red blood cells suggest kidney disease or injury to a kidney.

Casts: These are protein particles and fragments of kidney cells that may indicate the presence of kidney disease.

Crystals: These mineral fragments indicate susceptibility to kidney stones. Special urine tests may be carried out, including

Pregnancy Test: This shows whether a woman is pregnant, by detecting chorionic gonadotropin, a hormone produced to maintain the pregnancy.

Creatinine Clearance Test: This shows how well the kidneys are functioning by measuring the amount of creatinine present (a by-product of metabolism).

Urine Culture And Sensitivity: This can identify bacteria in the urine and analyze their sensitivity to different antibiotics.

Urine Amylase Test: By detecting the presence of the enzyme amylase, this test can check for possible inflammation of the pancreas (an organ which produces digestive enzymes).

How Are Urine Tests Carried Out?

Usually, you collect your own urine for analysis. The urine you pass first thing in the morning is highly concentrated and so provides the best specimen for testing certain substances.

For most urine tests, you simply collect a few milliliters or so of urine in a clean container. However, certain tests require a midstream specimen. To collect such a specimen you must first wash the genital area.

Next, you should briefly urinate into the toilet to dispose of the initial urine and any bacteria from the opening to the urethra (the tube which carries urine away from the bladder), and then deposit the next several milliliters of urine into a sterile container.

In rare instances, the doctor may remove urine with a catheter (a tube inserted directly into the bladder via the urethra), or via a needle passed through the abdominal wall. Ideally, the urine should reach the laboratory for analysis within an hour.

In the laboratory, the technician uses a plastic stick coated with a variety of reagents (chemicals which react to specific substances) which is dipped into the urine.

Changes of color on the stick provide information about pH, protein, glucose, ketones and blood. A urinometer is used to measure the specific gravity of urine.

Then, the technician places a small amount of urine in a test tube, which is spun for several minutes in order to separate out a drop of sediment for microscopic examination.

This sediment is used to screen the urine for cells, casts, crystals and bacteria. If your doctor wants a creatinine clearance test performed you will have to collect all your urine over a 24 hour period for laboratory analysis.

A urine amylase test requires either 2 hours or 24-hour urine collection. For diabetic urine tests, you will need to collect urine samples at specified times, usually before meals and at bedtime.


If you are collecting a urine specimen at home and cannot take it to the laboratory immediately, be sure to seal and refrigerate it. This will slow bacterial growth and help prevent deterioration of substances that must be evaluated.

Women should inform the doctor or laboratory technician if they are menstruating since the menstrual fluid in the urine sample can produce misleading results.

Do Urine Tests Cause Discomfort?

No. Normal urine retrieval is a simple process. However, if the doctor takes a urine sample by means of a needle, the insertion into the bladder may cause some discomfort, even though a local anesthetic will be administered first.

How Long Does Urine Test Take?

It only takes a few seconds to provide a urine sample, but laboratory analysis of the sample varies depending on what tests will be run.

A routine urine test takes less than half an hour; a urine culture takes 3 — 4 days. You will re-conveyor results any time from a few hours to several days after the laboratory receives the sample.

Are There Complications Associated With A Urine Test?

If the doctor uses a urinary catheter or needle there is a slight risk of acquiring an infection of the urinary tract. However, complications are not usually associated with routine urine tests.
