About This Quiz

Clinical Biochemistry is the division of laboratory medicine which entails the measurement of natural as well as unnatural chemicals in the blood, urine and several other fluids in the body. These test results are very useful for diagnosing health problems, determining prognosis and properly guiding the therapy of a patient. This quiz is for the purpose of testing your knowledge as regards this aspect of high medical importance.

    What's the closeness of agreement between the result of a measurement and the true value of a measurand?  - ProProfs

    What's the closeness of agreement between the result of a measurement and the true value of a measurand? 

    • Accuracy

    • Precision

    • Originality

    • Trueness 

    Correct Answer
    A. Accuracy
    Explanation
    Accuracy refers to the closeness of agreement between the result of a measurement and the true value of a measurand. It indicates how close the measured value is to the actual value, without considering the consistency or repeatability of the measurements. In other words, accuracy measures the correctness or validity of a measurement.

    Which of the following is the ability of the measuring procedure to determine only the measurand intended for determination?  - ProProfs

    Which of the following is the ability of the measuring procedure to determine only the measurand intended for determination? 

    • Analytical specificity 

    • Working range 

    • Analytical sensitivity 

    • Method verification 

    Correct Answer
    A. Analytical specificity 
    Explanation
    Analytical specificity refers to the ability of a measuring procedure to accurately determine only the specific measurand that it is intended to determine. In other words, it measures the ability of the procedure to distinguish and measure the target substance or analyte without interference from other substances. This is important in ensuring the accuracy and reliability of the measurement results.

    What's the closeness of agreement between independent measurement results obtained under pre-specified conditions?  - ProProfs

    What's the closeness of agreement between independent measurement results obtained under pre-specified conditions? 

    • Accuracy 

    • Trueness 

    • Originality

    • Precision

    Correct Answer
    A. Precision
    Explanation
    Precision refers to the closeness of agreement between independent measurement results obtained under pre-specified conditions. It is a measure of how consistent and reproducible the results are. Accuracy, on the other hand, refers to the closeness of a measured value to the true value. Trueness is the absence of systematic error in measurement, while originality is not relevant to the context of measurement agreement. Therefore, precision is the correct answer in this case.

    Which of the following isn't a condition that reference individuals should meet? - ProProfs

    Which of the following isn't a condition that reference individuals should meet?

    • Be pregnant

    • Age of 18

    • Be feeling subjectively well

    • Must not have donated blood in the last 5 months

    Correct Answer
    A. Be pregnant
    Explanation
    The question asks for a condition that reference individuals should not meet. The other options (age of 18, feeling subjectively well, and not donating blood in the last 5 months) are all conditions that reference individuals should meet. However, being pregnant is not a condition that reference individuals should meet, as it is specific to a certain group of individuals and not applicable to everyone.

    Rate this question:

  • 6. 
    Which of the following refers to values obtained from a selected group of individuals with a defined health condition? - ProProfs

    Which of the following refers to values obtained from a selected group of individuals with a defined health condition?

    • Reference interval 

    • Reference values 

    • Reference value distribution

    • Reference population

    Correct Answer
    A. Reference values 
    Explanation
    Reference values refer to values obtained from a selected group of individuals with a defined health condition. These values serve as a benchmark or standard against which the results of diagnostic tests can be compared. They provide a range of values that are considered normal for a specific population, helping healthcare professionals interpret test results and make accurate diagnoses. Reference values are essential in determining whether an individual's test results fall within the expected range for their specific health condition.

    The combination of the terms in a specific measurement result constitutes the property of the result referred to as which of the following? - ProProfs

    The combination of the terms in a specific measurement result constitutes the property of the result referred to as which of the following?

    • Accuracy 

    • Precision 

    • Trueness 

    • Originality 

    Correct Answer
    A. Accuracy 
    Explanation
    Accuracy refers to how close a measurement result is to the true or accepted value. It is determined by the combination of terms used in the measurement, such as the precision of the instrument used and the trueness of the measurement process. Therefore, accuracy is the property of the result that is determined by the combination of terms in a specific measurement. Originality is not relevant to measurement accuracy.

    The total area under the density curve is equal to what?  - ProProfs

    The total area under the density curve is equal to what? 

    • 1

    • 3

    • 2

    • -1

    Correct Answer
    A. 1
    Explanation
    The total area under the density curve represents the probability of the entire distribution. Since probabilities cannot exceed 1, the correct answer is 1.

    Which of the following isn't an overview of indirect method of reference interval estimation?  - ProProfs

    Which of the following isn't an overview of indirect method of reference interval estimation? 

    • Histogram plotting 

    • Data smoothing using the Golay-Savicky filter 

    • Plotting the derivation of measured value frequency to concentration logarithms

    • Calculation of intercept and slope of the curved line plotted in the dependence. 

    Correct Answer
    A. Calculation of intercept and slope of the curved line plotted in the dependence. 
    Explanation
    The correct answer is "Calculation of intercept and slope of the curved line plotted in the dependence." This is not an overview of the indirect method of reference interval estimation because it refers to the calculation of intercept and slope, which is a different concept. The indirect method typically involves techniques such as histogram plotting, data smoothing using filters, and plotting the derivation of measured value frequency to concentration logarithms.

    Analytical properties of the laboratory method includes how many terms?  - ProProfs

    Analytical properties of the laboratory method includes how many terms? 

    • 3

    • 5

    • 2

    • 1

    Correct Answer
    A. 2
    Explanation
    The correct answer is 2. This suggests that the analytical properties of the laboratory method are characterized by two terms. However, without further context or information about the laboratory method in question, it is difficult to provide a more detailed explanation.
