AUrinalysisis a group of tests done to examine your urine (pee). It finds and measures substances such as electrolytes, sugar (glucose), proteins, blood, cells and bacteria. It may also be called a urine test.
AUrinalysisis often done as part of a routine checkup, but it can be done at any time. It may be done to:
AUrinalysisis usually done in a laboratory or hospital. You dont typically need any special preparation for aUrinalysis. But in some cases, special instructions will be given to you to obey before aUrinalysisis completed. You may be told not to eat or drink anything for several hours (called fasting) or to avoid other foods.
It stores the urine in a clean bottle. For urinalysis, a random sample of urine is most commonly obtained. This ensures it produces a small volume of urine at any time of day. But you may be asked to collect the urine at a particular time of day, like first thing in the morning. The lab will give you directions about how to retrieve the urine and how long it should be stored. You should clean the genital region before collecting the urine sample (between the labia in women or the tip of the penis in men). Start urinating in the toilet (the first bit of urine you do not collect); Then collect any urine (called midstream urine or clean-catch) in the bottle.
A 24-hour sample of urine is often needed to help doctors better understand what is happening in the body. This ensures that all of the urine is collected over a 24-hour period. The urine is stored in a large container which often contains or has to be held cold with special preservatives. The laboratory will give you instructions for collecting the urine. A research expert (a research technologist) then analyses the urine sample. The urine is analyzed with special paper strips (called dipsticks) and a microscope.
AUrinalysisoffers general information which may offer clues to potential health issues for doctors.Urinalysisinformation lets physicians determine whether more testing or procedures are needed to make a diagnosis. The details will also assist the doctor in designing or revising treatment plans.
To have value, the findings of theUrinalysisshould be contrasted with a standard reference set. A doctor understanding your medical background and general health is the best source to clarify the findings of yourUrinalysisand what they mean for you.
AUrinalysisand its results are usually divided into 3 parts:
The following are some examples ofUrinalysisresults and what they may mean.
Standard urine is light to dark yellow and translucent. Some drugs or foods may cause an irregular colour in the urine. Cloudy urine can mean the sample contains blood cells or bacteria.
Urine is usually slightly acidic. Having urine that is very acid or very alkaline may mean you at increased risk of developing kidney stones (hard deposits of minerals such asCalciumthat start forming in the kidney). Certain substances are not usually found in urine.
Looking at urine through a microscope can find cells, parts of cells and bacteria or other germs.
Early Disease Detection: Urinalysis can detect various diseases and conditions at an early stage, even before symptoms appear. It helps identify underlying health issues such as urinary tract infections, kidney diseases, diabetes, liver problems, and certain types of cancer.
Non-invasive Procedure: Urinalysis is a non-invasive and relatively simple procedure. It only requires a urine sample, which can be easily obtained from the patient, making it a convenient diagnostic test.
Screening Tool: Urinalysis is an effective screening tool in healthcare settings. It helps identify abnormalities that may require further investigation or treatment. Routine urinalysis can be conducted during annual check-ups or pre-employment medical examinations to assess overall health.
Monitoring Treatment: Urinalysis allows healthcare professionals to monitor the progress of treatment or the effectiveness of medications. For example, in diabetes management, urine glucose levels can indicate whether blood sugar is being controlled adequately.
Kidney Function Evaluation: Urinalysis provides valuable information about kidney function. It can detect kidney-related issues, such as kidney infections, kidney stones, and impaired renal function. Additionally, the presence of protein or blood in the urine can indicate kidney damage or disease.
Pregnancy Monitoring: Urinalysis is commonly used during prenatal care to monitor the health of pregnant women and detect any potential complications. It helps identify conditions like gestational diabetes, urinary tract infections, preeclampsia, and kidney problems that can impact both the mother and the baby.
Drug Testing: Urinalysis is frequently employed in drug testing programs to detect the presence of illicit drugs or medications in a person's system. It is widely used in workplace drug testing, athletic competitions, and rehabilitation programs.
Hydration Assessment: The color, clarity, and specific gravity of urine can provide insights into an individual's hydration status. Urinalysis can help assess whether a person is adequately hydrated or experiencing dehydration.
Infection Diagnosis: Urinalysis aids in diagnosing urinary tract infections (UTIs) by identifying the presence of bacteria, white blood cells, or other signs of infection in the urine. This allows for prompt treatment with appropriate antibiotics.
Cost-Effective: Urinalysis is a cost-effective diagnostic tool compared to more complex and expensive tests. It provides valuable information about a person's health status, enabling timely interventions and preventing the progression of diseases.
It is important to note that while urinalysis offers many advantages, it is often used in conjunction with other diagnostic tests and clinical evaluations to form a comprehensive picture of a person's health.
