What is a key characteristic of quantitative tests?

Quantitative tests are designed to measure the concentration of specific substances within a sample. This characteristic allows for precise numerical values to be obtained, facilitating the assessment of how much of a given substance is present. Such tests are essential in various fields, including medical diagnostics, where accurate measurements can inform treatment decisions or monitor disease progression.

The focus on measuring specific concentrations highlights the test's ability to provide detailed data rather than just a yes/no or positive/negative outcome. This precise quantification is necessary for analyses that require understanding the levels of substances, such as hormones, enzymes, or toxins.

In contrast, some tests may utilize subjective interpretation, focus on binary results, or depend solely on visual assessments, which do not align with the objective and measurable nature of quantitative testing. These aspects highlight the importance of numerical data in quantitative assessments, making it a fundamental characteristic of this type of testing.
