Why might cost-efficiency be a critical advantage of certain testing methods?

Cost-efficiency is a critical advantage of certain testing methods because it makes testing accessible for more facilities. When a testing method is cost-effective, it lowers the overall financial barrier for various establishments, including schools, homes, and public buildings, enabling them to implement lead testing more frequently and broadly. This increased accessibility is crucial in addressing public health concerns related to lead exposure, as more facilities can engage in routine testing and thus identify potential lead hazards that need to be mitigated.

In contrast, methods that may be faster, require less training, or enhance precision do not inherently address the financial aspects of testing. If testing methods are too costly, even if they are quick or precise, many facilities may avoid utilizing them altogether. Thus, the cost-efficiency aspect directly influences how many facilities can participate in lead risk assessment programs, making it a key consideration in the selection of testing methods.
