What does a reagent test strip test in urine?
Urine Reagent Strips are firm plastic strips onto which several separate reagent areas are affixed. The test is for the detection of one or more of the following analytes in urine: Leukocytes, Glucose, Ketone (Acetoacetic acid), Bilirubin, Blood, Specific Gravity, Protein, Urobilinogen, Nitrite, Ascorbic Acid, and pH.
What indicates a urine infection on a dipstick?
Guidance from PHE [PHE, 2017] states that if dipstick is positive for nitrite or leukocyte and red blood cells (RBC) UTI is likely; if urine dipstick is negative for nitrite and positive for leukocyte, UTI is equally likely to other diagnoses; and if urine dipstick is negative for all nitrite, leukocyte and RBC UTI …
How do you read UTI test strip results?
Easy-to-Use: 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. Read insert inside for complete instructions.
How many leukocytes in urine are normal?
Diagnosis. If you’re healthy, you can still have elevated leukocytes in your bloodstream and urine. A normal range in the bloodstream is between 4,500-11,000 WBCs per microliter. A normal range in the urine is lower than in the blood, and may be from 0-5 WBCs per high power field (wbc/hpf).
What is reagent strip?
A urine reagent strip (dipstick) is a firm plastic strip to which pads saturated with chemicals are affixed. The chemicals in the pads indicate the presence of specific substances in the urine. The strips may also indicate the pH and specific gravity of the urine, depending on the type of strip that is used.
Which sugar S does the reagent strip detect?
Only glucose will be detected, because the reagent strip uses glucose oxidase. Other sugars must be detected by a test for reducing substances (Benedict’s copper reduction method) which will pick up such sugars as fructose.
Can leukocytes be present in urine without infection?
It is possible to have white blood cells in the urine without a bacterial infection. Sterile pyuria refers to the persistent presence of white blood cells in the urine when no bacteria are found to be present by laboratory examination.
Does positive leukocytes always mean UTI?

Can you buy test strips for urine tests?

What is the reagent used to test protein in urine?
Positive tests for protein in urine are due to the presence of albumin , the most abundant plasma protein. Because the protein reagent pad is not a good detector of globulins, the protein sulfosalicylic acid turbidity test should be used to detect proteins other than albumin.
