Urinalysis / Urine Testing / Urologic Screening
Urinalysis Testing in La Mesa, CA
Simple, high-value urine testing for urinary tract infection, blood in the urine, kidney stones, kidney disease, bladder infections, diabetes-related findings, protein, glucose, bacteria, nitrites, white blood cells, red blood cells, urine concentration, and ongoing urologic monitoring.
A urinalysis may be performed as part of a routine medical exam to screen for early signs of illness, or it may be ordered when symptoms suggest a urologic or kidney-related condition. It can include visual inspection, chemical dipstick testing, specific gravity testing, and microscopic analysis.
Bacteria, nitrites, leukocyte esterase, and white blood cells may suggest a urinary tract infection.
Blood, red blood cells, crystals, pH, and concentration can support evaluation for stones or hematuria.
Protein, albumin, glucose, ketones, and specific gravity can provide clues about kidney or metabolic disease.

What a Urinalysis May Check
A urinalysis may check the physical appearance of the urine as well as chemical and microscopic findings. These results help the physician decide whether further testing, treatment, or monitoring is needed.
Urine appearance may be affected by hydration, infection, blood, medications, foods, or other factors.
Chemical testing can screen for acidity, protein, sugar, blood, ketones, bilirubin, nitrites, and leukocyte esterase.
A microscopic exam can look for red blood cells, white blood cells, bacteria, casts, crystals, and other urinary sediment.
- Color
- Odor
- Clarity
- pH levels
- Specific gravity and urine concentration
- Protein or albumin
- Glucose
- Ketones
- Blood
- Bacteria
- Red blood cells
- White blood cells
- Nitrites
- Leukocyte esterase
- Pregnancy-related hormone testing when clinically appropriate
A urinalysis result is not interpreted in isolation. The physician considers symptoms, medical history, medications, hydration, sample quality, urine culture results when ordered, and whether additional testing is needed.
Reasons for Urinalysis
Urinalysis is used to detect or monitor various conditions and diseases, including:
- Urinary tract infection
- Bladder infection
- Kidney stones
- Kidney disease
- Blood in the urine
- Diabetes-related urine findings
- High blood pressure-related kidney concerns
- Protein in the urine
- Chronic urinary symptoms
- Monitoring chronic urologic or kidney-related conditions
Burning urination, urgency, frequency, pelvic pain, fever, or cloudy urine may prompt urine testing.
Blood seen in urine or detected microscopically may require repeat urinalysis and urologic evaluation.
Flank pain, crystals, blood, pH changes, protein, or abnormal kidney-related findings may need further workup.
Urinalysis may also be part of routine screening, pre-procedure testing, pregnancy-related care, post-treatment follow-up, or monitoring for chronic conditions.
Methods of Urinalysis
The mechanics of testing urine collected in a urinalysis may be performed in several different ways. Some results are available quickly in the office, while others may require laboratory processing.
Dipstick Tests
A test strip or stick can be dipped into the specimen, producing a color change that indicates positive or negative results for specific findings such as blood, protein, glucose, nitrites, leukocyte esterase, pH, ketones, and specific gravity.
Physical Observation
A straightforward observation of the urine sample measures physical characteristics such as color, clarity, odor, and visible sediment.
Specific Gravity and Concentration
A doctor or laboratory may evaluate the specific gravity of urine to estimate urine concentration and hydration-related patterns. A refractometer or automated analyzer may be used.
Microscopic Analysis
A urine sample may be examined under a microscope to look for indications of infection, bacteria, white blood cells, red blood cells, crystals, casts, and other substances that can be indicators of certain conditions.
Urine Culture When Needed
If infection is suspected or symptoms are recurrent, a urine culture may be ordered to identify bacteria and help guide antibiotic selection.
Understanding Urinalysis Results
Urinalysis results can provide clues, but they do not always give a final diagnosis by themselves. Abnormal findings may need repeat testing, urine culture, blood work, imaging, cystoscopy, or other urologic evaluation.
These may suggest infection, especially when symptoms such as burning, urgency, or frequency are present.
Blood may be related to infection, stones, prostate issues, kidney disease, bladder conditions, or other causes.
Protein can be a clue for kidney disease, inflammation, infection, or temporary changes that need clinical interpretation.
When Results Suggest Infection
If urinalysis suggests a urinary tract infection, the physician may recommend antibiotics, urine culture, hydration guidance, symptom monitoring, repeat testing, or further evaluation if infections recur.
When Results Show Blood
Blood in the urine may need additional evaluation, especially if it persists or is not clearly explained by infection, stones, recent activity, menstruation, or another temporary factor.
When Results Suggest Kidney or Metabolic Issues
Protein, glucose, ketones, casts, abnormal specific gravity, or persistent abnormal findings may require blood tests, kidney function monitoring, urine albumin-to-creatinine ratio, imaging, or coordination with a primary care clinician or kidney specialist.
Preparing for a Urinalysis
It is important to notify the doctor of any medications or vitamins the patient is currently taking before undergoing a urine analysis. Many forms of medication, vitamins, supplements, and foods can affect the appearance or results of this test.
Tell the doctor about prescriptions, over-the-counter medicines, vitamins, and supplements.
Many urine tests use a clean-catch midstream sample to reduce contamination.
Report burning, urgency, frequency, pain, fever, blood, flank pain, discharge, or recent antibiotics.
- Tell the office if you are taking antibiotics or recently finished them
- Report fever, flank pain, pelvic pain, visible blood, or inability to urinate
- Tell the clinician about pregnancy possibility when relevant
- Ask whether a first-morning sample, random sample, or timed collection is needed
- Follow clean-catch instructions carefully if provided
- Ask whether a urine culture is needed if UTI symptoms are present
Follow-Up After Urinalysis
Follow-up depends on the urinalysis findings and the reason for testing. Some results require no treatment, while others need repeat testing, medication, culture, imaging, cystoscopy, or ongoing monitoring.
A repeat urinalysis may be recommended if results are borderline, contaminated, or need confirmation.
Culture may be used to confirm infection and determine which antibiotics may work best.
Persistent blood, recurrent infection, stones, obstruction symptoms, or abnormal results may require urologic workup.
Related Urology Services
Depending on the result, related care may include UTI treatment, hematuria evaluation, kidney stone care, cystoscopy, cystogram, pelvic ultrasound, urodynamic testing, bladder cancer evaluation, prostate evaluation, or chronic kidney disease monitoring.
Common questions about urinalysis.
These answers are general educational information and are not a substitute for diagnosis or treatment. A physician can explain what your urine test results mean in your specific case.
What is a urinalysis?
A urinalysis is a urine test that checks the appearance, chemistry, and sometimes microscopic contents of urine to look for clues about infection, kidney disease, diabetes, bleeding, stones, and other conditions.
Why would a urologist order a urinalysis?
A urologist may order urinalysis for burning urination, urgency, frequency, blood in the urine, kidney stone symptoms, bladder pain, recurrent UTIs, kidney concerns, or routine monitoring.
What does a dipstick test check?
A dipstick test may check pH, protein, glucose, ketones, blood, nitrites, leukocyte esterase, bilirubin, and urine concentration depending on the test strip used.
What does microscopic urinalysis look for?
Microscopic analysis may look for red blood cells, white blood cells, bacteria, crystals, casts, and other urine sediment.
Can urinalysis diagnose a UTI?
Urinalysis can support a UTI diagnosis when symptoms and urine findings match. A urine culture may be ordered when confirmation or antibiotic guidance is needed.
What does blood in the urine mean?
Blood in the urine can have many causes, including infection, stones, prostate conditions, kidney disease, bladder conditions, recent activity, contamination, or other issues. Persistent blood should be evaluated.
What does protein in urine mean?
Protein in urine may be temporary or may suggest kidney disease, infection, inflammation, high blood pressure effects, diabetes-related kidney changes, or other conditions that require follow-up.
Can medications or vitamins affect urinalysis results?
Yes. Some medications, vitamins, supplements, foods, hydration patterns, and recent antibiotics can affect urine color or test results. Tell the doctor what you take before testing.
Will abnormal urinalysis results always mean disease?
No. Some abnormal results are temporary, contaminated, or related to hydration, medication, recent activity, or collection technique. Your physician may recommend repeat testing or additional evaluation.
