What is OSUR institutional ownership?
This page tracks OSUR positions reported by institutional investment managers through SEC Form 13F. ORASURE TECHNOLOGIES INC (OSUR) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own OSUR?
InsiderSet currently tracks 149 institutional managers reporting OSUR holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of OSUR shareholders.
How much OSUR stock do institutions own?

The latest OSUR institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
