How do I read my urinalysis results?
Normal values are as follows:
- Color – Yellow (light/pale to dark/deep amber)
- Clarity/turbidity – Clear or cloudy.
- pH – 4.5-8.
- Specific gravity – 1.005-1.025.
- Glucose – ≤130 mg/d.
- Ketones – None.
- Nitrites – Negative.
- Leukocyte esterase – Negative.
What do the urinalysis findings indicate?
A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.
What indicates a UTI in a urinalysis?
An increased number of WBCs seen in the urine under a microscope and/or positive test for leukocyte esterase may indicate an infection or inflammation somewhere in the urinary tract. If also seen with bacteria (see below), they indicate a likely urinary tract infection.
What does it mean if urinalysis is high?
Highly concentrated urine can be a sign of dehydration. Nitrites in urine can indicate a bacterial infection such as a urinary tract infection. Proteins in urine can indicate kidney disease or kidney damage.
What is the normal range for bacteria in urine?
Urine is normally sterile. However, in the process of collecting the urine, some contamination from skin bacteria is frequent. For that reason, up to 10,000 colonies of bacteria/ml are considered normal. Greater than 100,000 colonies/ml represents urinary tract infection.
What is a high bacteria count in urine?
Bacterial colonization in urine is high when the level of bacterial counts is elevated— meaning the number of colonies of a single organism is higher than 100,000 per mL. If the bacteria level in your urine is high and it’s causing physical symptoms, you have a symptomatic urinary tract infection (UTI).
What infections can be found in urine?
The most common infections diagnosed by urinalysis are UTIs, which are one of the most common bacterial infections that require medical intervention. Several other infections such as community-acquired pneumonia and viremia infections can also be diagnosed with the help of urinalysis.
What does leukocytes in urine indicate?
If your doctor tests your urine and finds too many leukocytes, it could be a sign of infection. Leukocytes are white blood cells that help your body fight germs. When you have more of these than usual in your urine, it’s often a sign of a problem somewhere in your urinary tract.
How do you treat leukocytes in urine?
Treatment for leukocytes in the urine depends on the cause and if there is an infection. For some conditions, such as a bacterial UTI, antibiotic therapy will clear up the infection relatively quickly. For more severe infections or those that will not resolve easily, more in-depth medical treatment may be needed.
What does it mean when your urine test positive for nitrates?
The presence of nitrites in urine most commonly means there’s a bacterial infection in your urinary tract. This is usually called a urinary tract infection (UTI).
What is a positive UA for UTI?
A positive test for nitrites in the urine is called nitrituria. This test is commonly used in diagnosing urinary tract infections ( UTIs ). A positive nitrite test indicates that the cause of the UTI is a gram negative organism, most commonly Escherichia coli .
What is urodynamics test, and why is it needed?
Urodynamic testing is a sophisticated office-based procedure to help diagnose problems with urination and/or urinary incontinence (involuntary loss of urine). This type of testing studies the function and dysfunction of the lower urinary tract.
What is a lab urine test?
The urinalysis test, sometimes known as a urine test or a UA test, is a commonly run generic urine screening test that checks for various markers in the urine. Important markers checked in the UA lab test include the color, appearance, specific gravity, pH, glucose, bilirubin, ketones, occult blood, protein, nitrite, leukocyte esterase and WBC.
What are the results of uti?
A urinary tract infection (also called a “UTI”) is what happens when bacteria (germs) get into the urinary system and multiply. The result is redness, swelling, and pain. If the infection is not treated promptly, the bacteria can travel up to the kidneys and cause a more serious type of infection, called pyelonephritis .
