Point-of-Care Testing (POCT) Certificate Practice Exam 2025 - Free POCT Practice Questions and Study Guide

Qualitative tests are designed to determine the presence or absence of a particular substance rather than quantifying the amount of that substance. In the context of the given question, HIV screening is typically performed using qualitative tests that can identify antibodies or antigens related to the HIV virus. These tests, such as rapid tests or enzyme-linked immunosorbent assays (ELISA), can indicate whether a person is positive or negative for HIV but do not provide a numerical value for the viral load or number of antibodies.

Other assessments like blood glucose measurement, blood pressure monitoring, and cholesterol testing generally involve quantitative tests that provide specific numerical values. For instance, blood glucose measurements determine the exact glucose concentration in the blood, while cholesterol testing quantifies different types of cholesterol levels (total, HDL, and LDL). Blood pressure monitoring gives a precise reading of systolic and diastolic pressures. Hence, amongst the options provided, HIV screening is the correct choice for an assessment that can be performed through qualitative testing.
