What type of result does quantitative testing yield?

Quantitative testing is designed to provide precise and measurable information about the amount or concentration of specific substances within a sample. When performing quantitative tests, the outcome is typically presented as numerical data, which reflects exact measurements of the amounts of the analytes being tested. This is crucial in many scientific and clinical applications, where knowing the precise concentration of a substance can significantly influence diagnosis and treatment decisions.

In contrast, other types of results do not provide this level of specificity. A binary yes or no answer only indicates presence or absence without quantifying how much of a substance is present. Similarly, a list of components without amounts would identify the substances present but would not provide information on their concentrations. Descriptions of the sample's characteristics, while informative, do not offer the quantitative data critical for many analyses. Hence, the focus on exact measurements in quantitative testing distinguishes it clearly as the correct answer.
