reliability, and compliance with ethical and regulatory standards.

Scope

This SOP applies to Principal Investigators, sub-investigators, study coordinators, and site staff conducting eligibility verification. It covers the process of medical evaluation, laboratory assessments, documentation, and approval of eligibility status prior to subject enrollment.

Responsibilities

• Principal Investigator (PI): Reviews and confirms participant eligibility before enrollment.
• Sub-Investigators: Conduct clinical evaluations, apply inclusion/exclusion criteria, and document findings.
• Study Coordinator: Maintains eligibility verification logs and ensures documentation completeness.
• Sponsor/CRO: Verifies eligibility compliance during monitoring visits.
• Quality Assurance Officer: Audits eligibility verification records for accuracy and compliance.

Accountability

The PI is ultimately accountable for ensuring participants meet all inclusion criteria and none of the exclusion criteria before enrollment. Sponsors are accountable for oversight through monitoring and audits.

Document findings in the Eligibility Verification Log (Annexure-1).

4. Verification of Exclusion Criteria
Assess exclusion criteria (e.g., co-morbid conditions, concurrent medications, pregnancy, previous participation in related studies).
Record disqualifications with supporting documentation.

5. Final PI Review
PI reviews all eligibility documentation.
PI signs and dates the Eligibility Checklist to confirm decision.

6. Documentation and Filing
