What effect may bacterial contamination have on urine pH? a. The bacteria may make the pH more alkaline. b. The bacteria may make the pH more acidic. c. The bacteria would not affect urine pH. a. The bacteria may make the pH more alkaline A urine pH 8.0 may indicate that a specimen has been held unpreserved too long, which allows multiplication of urea-splitting bacteria with resultant increase in pH.
Excessive carbohydrates loss that may occur due to vomiting or rapid weight loss may result in the presence of which of following substances not normally contained in the urine? a. Glucose b. Bilirubin c. Ketones d. Uribilinogen c. Ketones Normal urine specimens usually yield negative results for the presence of ketones. Low levels of ketones may be detected in the urine during conditions of physiological stress such as a fasting, rapid weight loss, frequent strenous exercise or prolonged v
Which of the following statements is TRUE regarding the reagent strip test procedure? a. Urine should be centrifuged prior to dipping the reagent strip. b. Urine should be well mixed prior to dipping the reagent strip. c. When visually reading the reagent a. Urine should be centrifuged prior to dipping the reagent strip. Urine should be well mixed prior to dipping the reagent strip. Urine should NOT be centrifuged prior to dipping the reagent strip. Not all reagent strip tests can be read immediately after dipping the reagent strip into the urine specimen; the manufacture
Urine should be at room temperature prior to testing with the reagent strip method. a. True b. False a. True This statement is true. Urine should be room temperature prior to testing with the reagent strip method. Urine strip reactivity can increase with increased urine temperature, so the optimum temperature is 22-26°C, or room temperature.
The reagent strip method for protein primarily tests for which type of protein? a. Globulin b. Bence-Jones protein c. Albumin c. Albumin The urine reagent strip method for protein primarily indicates increased albumin, although other proteins may also produce a positive result if greatly elevated.
Which of the following urine chemical reagent strip tests is based on the Erlich-aldehyde reaction? a. pH b. Protein c. Glucose d. Urobillinogen e. Specific gravity d. Urobilinogen The urobilinogen urine chemical reagent strip test is based on the Erlich-aldehyde reaction. In this test, a pink-red color forms in proportion to the amount of urobilinogen present.
Sulfosalicylic acid can be used to confirm the result of which of the following test included on a urine chemical reagent strip? a. Protein b. Glucose c. Bilirubin d. Urobilinogen a. Protein The SSA reaction is used to detect protein in the urine. It is sometimes used as a secondary method if interfering urine color makes it difficult to read the color reaction on the urine reagent strip.
A patient who has a primarily vegetarian diet will most likely have an acidic urine pH. Select true or false. a. True b. False b. False This statement is false. A patient who has a primarily vegetarian diet will most likely have an alkaline urine pH. A low-carbohydrate diet as well as the ingestion of citrus fruits can also lead to a more alkaline urine sample.
Match the following urine reagent strip test pads to the disease or disorder that would most likely cause a positive test result. Ketones Blood Bilirubin Nitrites Ketones - Diabetes mellitus Blood - Renal calculi Bilirubin - Hepatitis/Cirrhosis Nitrites - Urinary Tract Infection

What is a reagent strip test?

Diagnostic reagent strips are commonly used in clinical analysis of urine and blood, in particular for monitoring glucose concentration. Results are obtained instrumentally or visually as thresholds and quantitative outputs. Dry reagents are applied in the construction of strips in a variety of ways.

Which procedure is correct when performing chemical examination of urine by the reagent strip?

Use a fresh, well-mixed, uncentrifuged urine. Hold the reagent strip by the opposite end from the test areas and dip the stick into the specimen so that all test areas are immersed in the specimen. Remove the stick immediately. Prolonged immersion in the sample may wash out the test reagents.

Which of the following statements is true for specific gravity measured by the urine chemical reagent strip method quizlet?

Which of the following statements is TRUE for specific gravity measured by the urine chemical reagent strip method? The urine chemical reagent strip method is not affected by the presence of x-ray contrast media in the urine specimen.

What are the protocols for urinalysis chemical strips quizlet?

dip the reagent strip briefly into a well-mixed uncentrifuged urine specimen at room temp..
remove excess urine by touching the edge of the strip to the container as the strip is withdrawn..
blot the edge of the strip on a disposable absorbent pas..
wait the specified amount of time for the rxn to occur..
