Which characteristic is NOT typically true about first-line testing?

First-line testing is designed to be straightforward and accessible, making it an essential part of initial assessments in medical settings. A key characteristic of first-line testing is that it is less invasive, which encourages patient compliance and makes it suitable for widespread use, particularly in screenings. These tests often have a lower cost, making them more feasible for both patients and healthcare systems, and their primary purpose is to identify potential health issues early, facilitating timely interventions.

In contrast, first-line tests typically do not involve complex procedures. They are designed to be quick and easy to perform, enabling healthcare providers to obtain reliable results without the need for extensive technical expertise or sophisticated equipment. This helps ensure that a wider population can be tested efficiently. Thus, the statement about complex procedures is not a characteristic of first-line testing, as such tests are intentionally simple to maximize their applicability and effectiveness in various healthcare scenarios.
