Screening tells you if something is worth a closer look; a lab result is the number you can act on.

    Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb

    Turnaround: 5 minutes

    What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
