Reviewed June 2026 by Enterprise Health

Key facts

  • Specific contact with blood/infectious material (often a needlestick).
  • Requires prompt post-exposure evaluation and follow-up.
  • Defined under the Bloodborne Pathogens Standard.

What it means

Under the Bloodborne Pathogens Standard, an exposure incident — most often a needlestick — requires prompt post-exposure evaluation, source testing where possible, and follow-up that may include prophylaxis. Speed matters, so documenting the incident, baseline labs and follow-up in one connected record is critical in health-care settings.
