What does a reagent test strip test in urine?
Tanner Scientific® 10 Reagent Strips for Urinalysis provide tests for Glucose, Bilirubin, Ketone (acetoacetic acid), Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite and Leukocytes in urine.
What is the best brand of urine test strips?
The Multistix® 10 SG reagent strip is the reliable frontline test for detection of a broad range of conditions, from detecting urinary tract infections (UTI1) to diabetes and kidney disorders.
Is urine strip test accurate?
A positive urine dipstick has a great chance of being false positive. The average of the positive predictive value in the studies shows 61 percent. However, a negative urine dipstick seems to be more reliable, in which the negative predictive value shows an average of 83 percent.
How long should you wait before interpreting the reagent strip?
Read results after 60 seconds for all reagent areas, except Leukocytes after 60-120 seconds, by comparing the reagent areas to the closest corresponding color blocks on the color chart. See illustration 3 below.
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.
Does diabetes show in urine test?
A urine test for glucose on its own can’t diagnose diabetes. It will show your doctor if there is any sugar in your urine, not how much or the possible cause.
How long does it take for a test strip to work?
The hormone hCG may be detected in urine about 2 weeks after conception (when the egg is fertilized by sperm). With the home test kit, you place a drop of your urine on a prepared chemical strip. It usually takes 1 or 2 minutes for the strip to indicate the result.
What are the limitations of a urine dipstick for reagent strip test?
Urine test strips used for visual analysis often have a pH reagent pad. A limitation of the reagent pad is that it only measures the ionic solutions and can be susceptible to pH readings.
Why is reagent strip important?
To ensure early detection of disease, manufacturers of quality reagent strips strive to provide a product that offers accurate results within as little time as one minute. Reagent strips can provide accurate results only if they are properly handled and stored in accordance with manufacturer recommendations.
