What type of result does a glucose level test provide?

A glucose level test provides a quantitative result because it measures the exact concentration of glucose present in the blood, typically expressed in milligrams per deciliter (mg/dL). This precise measurement allows for clear evaluation of a person's blood sugar levels, which is critical for diagnosing and managing conditions like diabetes.

Quantitative tests are characterized by providing numerical values that can be used for comparison against standard reference ranges. In contrast, qualitative results would indicate the presence or absence of a substance (for example, positive or negative), without providing specific numerical data. The other options, such as critical and subjective, do not accurately describe the nature of this test's results. Critical results refer to values that are dangerously abnormal, while subjective involves personal interpretations rather than objective measurements. Hence, the nature of a glucose level test aligns with quantitative results, making it the correct choice.
