PHCH 667 EXAM 1 QUESTIONS AND ANSWERS 1. Predictive value for a positive Qualitative Test is best describes as: a. both answers are correct b. PPV = TP/(TP+FP) - the number of a true positive values divided by all observed positive values c. NPV = TN/(TN+FN) - the number of true negative values divided by all observed negative values ANSW-b.

PHCH 667 INTRODUCTION TO CLINICAL CHEMISTRY EXAM 1 STUDY GUIDE QUESTIONS AND ANSWERS What is the most commonly used "acceptable level of significance" used in clinical chemistry? ANSW-95% What is a reference range? ANSW-Normal or reference range is typically range where values of 95% of the "healthy" individuals are within, anything outside is abnormal and is considered a critical value What is specificity and how is it calculated? ANSW-Specificity: proportion of H...

PHCH 667 INTRODUCTION TO CLINICAL CHEMISTRY EXAM 1 How do we understand the likelihood that the results of a given test are valid? ANSW through statistics! why is statistics used in clinical chemistry? ANSW-determination of "normal range" and validity of a test what are the assay parameters for quantitative tests? ANSW-• Accuracy • Precision • Reference values • Critical value

Accuracy - mean, how close to actual value Precision - Standard deviation, how close values are to each other The most important key parameters of a qualitative test - reference values, predictive values, specificity The key parameters of a quantitative test - accuracy, reference values, sensitivity The reference range most acceptable for quantitative tests - within 95% of the mean value For quantitative tests, critical values typically are considered those that occur where? ...
