    • PROTEIN PRECIPITATION TEST

    • KETODIASTIX

    • MICROALBUMIN TEST STRIPS

    • CLINITEST

    Correct Answer
    A. PROTEIN PRECIPITATION TEST
    Explanation
    The correct answer is "PROTEIN PRECIPITATION TEST". This test is used to confirm the presence of protein in urine. It involves the use of dilute sulfosalicylic acid or acetic acid, which causes any protein present in the urine (such as albumin and globulin) to precipitate. This precipitation can then be observed and confirmed as a positive result for protein in the urine. The other options listed are not specific tests for protein in urine.

     A GOOD COMPREHENSIVE QUALITY ASSESSMENT (MONITORING) PROGRAM IN THE URINALYSIS SHOULD INCLUDE _____________________ 

    • SPECIMEN COLLECTION

    • QUALITY CONTROL AND TESTING

    • REPORTING

    Correct Answer(s)
    A. SPECIMEN COLLECTION
    A. QUALITY CONTROL AND TESTING
    A. REPORTING
    Explanation
    A good comprehensive quality assessment (monitoring) program in urinalysis should include specimen collection, quality control and testing, and reporting. Specimen collection is important to ensure that the sample obtained is representative of the patient's urine and is free from contamination. Quality control and testing involve following standardized procedures, using proper equipment, and ensuring accuracy and precision in the analysis of the urine sample. Reporting involves documenting and communicating the results accurately and in a timely manner to healthcare providers for appropriate diagnosis and treatment.

    THE REFERENCE RANGE OF URINE LEUKOCYTE ESTERASE IS:

    • NEGATIVE

    • 5.0 - 8.0

    • NEGATIVE OR TRACE

    • SPECIFIC GRAVITY

    • 1.010 - 1.025

    • 0.0 - 1.0mg/dL

    Correct Answer
    A. NEGATIVE
    Explanation
    The correct answer is "NEGATIVE" because the reference range for urine leukocyte esterase is negative. This means that if the test result shows a negative value for leukocyte esterase, it indicates the absence of white blood cells in the urine, which is considered normal.

    THE INDICATOR OF EARLY RENAL DISEASE IS:

    • GLUCOSE

    • MICROALBUMIN

    • BILIRUBIN

    Correct Answer
    A. MICROALBUMIN
    Explanation
    Microalbumin is a protein that is normally found in the blood at very low levels. However, when the kidneys are not functioning properly, small amounts of albumin can leak into the urine. This is known as microalbuminuria and it is an early indicator of renal disease. Monitoring microalbumin levels can help detect kidney damage in its early stages, allowing for timely intervention and treatment to prevent further complications. Glucose and bilirubin are not specific indicators of renal disease and are not commonly used to assess kidney function.

    CHECK ALL CONDITIONS THAT THE CHEMICAL ANALYSIS OF URINE CAN PROVIDE INFORMATION FOR:

    • CARBOHYDRATE METABOLISM

    • KIDNEY FUNCTION

    • LIVER FUNCTION

    • PH BALANCE

    • TEETH FUNCTION

    • KIDNEY FUNCTION

    Correct Answer(s)
    A. CARBOHYDRATE METABOLISM
    A. KIDNEY FUNCTION
    A. LIVER FUNCTION
    A. pH BALANCE
    A. KIDNEY FUNCTION
    Explanation
    The chemical analysis of urine can provide information for carbohydrate metabolism, kidney function, liver function, and pH balance. The presence of certain substances in urine can indicate abnormalities in carbohydrate metabolism, such as the presence of glucose in cases of diabetes. The levels of certain chemicals and waste products in urine can also indicate how well the kidneys are functioning, as they are responsible for filtering waste from the blood. Similarly, the liver plays a role in detoxification and metabolism, and abnormalities in liver function can be detected through urine analysis. pH balance refers to the acidity or alkalinity of urine, which can be indicative of certain health conditions.

    WHICH OF THE FOLLOWING TESTS IS CLIA WAIVED?

    • QUANTITATIVE URINE BETA HGC TEST

    • CHEMICAL ANALYSIS OF URINE BY REAGENT STRIP METHOD

    • MICROSCOPIC EVALUATION OF URINE

    Correct Answer
    A. CHEMICAL ANALYSIS OF URINE BY REAGENT STRIP METHOD
    Explanation
    The correct answer is "CHEMICAL ANALYSIS OF URINE BY REAGENT STRIP METHOD" because this test is considered CLIA waived. CLIA waived tests are simple laboratory examinations and procedures that have been cleared by the FDA for home use and are considered to be simple and accurate enough to be performed without the need for extensive laboratory training or supervision. The other two options, quantitative urine beta HGC test and microscopic evaluation of urine, are not considered CLIA waived tests.

    THE REFERENCE RANGE OF URINE GLUCOSE IS:

    • NEGATIVE

    • 5.0 - 8.0

    • NEGATIVE OR TRACE

    • SPECIFIC GRAVITY

    • 1.010 - 1.025

    • 0.0 - 1.0mg/dL

    Correct Answer
    A. NEGATIVE
    Explanation
    The correct answer is "NEGATIVE" because the reference range for urine glucose is usually negative, meaning that there should be no glucose present in the urine. Glucose is typically filtered out by the kidneys and reabsorbed back into the bloodstream, so its presence in the urine may indicate a problem with glucose regulation, such as diabetes. Therefore, a negative result is considered within the normal range.

    THE REFERENCE RANGE OF URINE BILIRUBIN IS:

    • NEGATIVE

    • 5.0 - 8.0

    • NEGATIVE OR TRACE

    • SPECIFIC GRAVITY

    • 1.010 - 1.025

    • 0.0 - 1.0mg/dL

    Correct Answer
    A. NEGATIVE
    Explanation
    The correct answer is "NEGATIVE". This is because the reference range for urine bilirubin is negative, meaning that there should be no presence of bilirubin in the urine. Bilirubin is a pigment that is produced when red blood cells are broken down, and its presence in the urine can indicate liver or gallbladder dysfunction. Therefore, a negative result is considered within the normal range.
