What Are Normal Urinalysis Results?

Color – Yellow (light/pale to dark/deep amber) Clarity/turbidity – Clear or cloudy. pH – 4.5-8. Specific gravity – 1.005-1.025.

What is considered a positive urine test?

An alternative definition for bacteriuria is 2+ present on urinalysis (representing 100 CFU/mL); this may be considered positive in selected populations, such as catheterized or strongly symptomatic patients.

What do you expect on the results of the urinalysis?

A typical urinalysis involves a visual exam, a dipstick test, and a microscopic exam. Urine acidity (pH) level may indicate kidney stones or urinary infections. The level of acidity can be affected by diet, chemical imbalances, and certain metabolic disorders.

What is normal range for urinalysis?

According to the American Association for Clinical Chemistry, the average value for urine pH is 6.0, but it can range from 4.5 to 8.0. Urine under 5.0 is acidic, and urine higher than 8.0 is alkaline, or basic.

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 are some examples of abnormal findings in a urinalysis?

Things the dipstick test can check for include:

  • Acidity, or pH. If the acid is abnormal, you could have kidney stones, a urinary tract infection (UTI), or another condition.
  • Protein. This can be a sign your kidneys aren’t working right.
  • Glucose.
  • White blood cells.
  • Nitrites.
  • Bilirubin.
  • Blood in your urine.

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 should not be found in urine?

Usually, glucose, ketones, protein, and bilirubin are not detectable in urine. The following are not normally found in urine:

  • Hemoglobin.
  • Nitrites.
  • Red blood cells.
  • White blood cells.

How do you read a urinary tract infection test?

Simply wet one test strip by holding it in your urine stream for 1-2 seconds. Read result at 1 minute for Nitrite and at 2 minutes for Leukocytes. Match the color of the test strip pads to the color blocks on the foil pouch.

What is normally in urine?

Urine is an aqueous solution of greater than 95% water. Other constituents include urea, chloride, sodium, potassium, creatinine and other dissolved ions, and inorganic and organic compounds. Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide.

What is normal bacteria in urine?

Normal urine has no bacteria. But if bacteria get into the urethra (the tube that empties urine from the bladder to the outside) and travel into the bladder, a UTI can occur. The infection most often starts in the bladder, but can spread to the kidneys. UTIs can cause pain in your abdomen and pelvic area.

What does a 7.5 pH in urine mean?

Normal urine pH is slightly acidic, with usual values of 6.0 to 7.5, but the normal range is 4.5 to 8.0. A urine pH of 8.5 or 9.0 is often indicative of a urea-splitting organism, such as Proteus, Klebsiella, or Ureaplasma urealyticum.

What is normal E coli count in urine?

For that reason, up to 10,000 colonies of bacteria/ml are considered normal. Greater than 100,000 colonies/ml represents urinary tract infection. For counts between 10,000 and 100,000, the culutre is indeterminate.

Is 3+ bacteria in urine bad?

Patients with dipstick results of 3+ or greater may have significant proteinuria; further work-up is indicated. Patients with microscopic hematuria (i.e., at least three red blood cells per high-power field in two of three specimens) should be evaluated to exclude renal and urinary tract disease.

What does 50000 CFU mL mean?

d) In an appropriately collected specimen, 50,000 colony-forming units/milliliter (CFU/mL) should be considered the threshold for diagnosis of UTI. e) For infants under 6 months, boys (especially if uncircumcised) are more likely than girls to experience a UTI; after 6 months, UTIs are five times more common in girls.
