Clinical Chemistry 1

It is the ability of an analytical method to measure the smallest concentration of the analyte of interest.

• Sensitivity

• Specificity

• Accuracy

• Precision

It is the ability of an analytical method to give repeated results on the same sample that agree with one another.

• Accuracy

• Precision

• Specificity

• Sensitivity

How are control limits being calculated?

• By mean and median.

• By mean and standard deviation.

• By mean and coefficient of variation.

• By standard deviation and coefficient of variation.

It reflects the ability of the method to detect true-negative with very few false-positives.

• diagnostic specificity

• diagnostic sensitivity

• reliability

• practicability
