Quest Diagnostics

Quest Diagnostics's $3.0M in disclosed federal lobbying puts it in the mid-tier of registered filers. Spending in the seven-figure range is common for established trade groups, mid-size corporations, and advocacy organizations that maintain a steady but not aggressive presence on Capitol Hill.

Across the 5-year window from 2020 to 2024, Quest Diagnostics's annual disclosed lobbying spend has climbed modestly — from $521K in 2020 to $554K in 2024, a change of +6%. Step-changes of this size often coincide with major bills moving through Congress, regulatory rulemakings affecting the organization's industry, or a leadership change in the relevant committee.

Quest Diagnostics's disclosed lobbying focuses on a narrow 3-issue footprint. A focused issue list usually means the organization concentrates its federal engagement on a small set of bills or rulemakings directly relevant to its core business.
