Standard Operating Procedure for Bioanalytical Testing and Result Reporting
| SOP No. | CR/OPS/087/2025 |
| Supersedes | NA |
| Page No. | 1 of 42 |
| Issue Date | 26/08/2025 |
| Effective Date | 01/09/2025 |
| Review Date | 01/09/2026 |
Purpose
The purpose of this SOP is to outline standardized, regulatory-compliant procedures for performing bioanalytical testing and reporting results from clinical trial samples. This ensures
Scope
This SOP applies to all laboratory staff, CROs, and sponsors involved in the analysis of clinical trial biological samples. It covers sample preparation, assay validation, instrument operation, calibration curve generation, QC sample monitoring, data review, reporting, deviations, and record archiving.
Responsibilities
- Bioanalytical Laboratory: Conducts testing, validates assays, and reports results.
- Laboratory Analysts: Perform sample preparation, testing, and documentation.
- QA: Audits laboratory compliance with GLP, GCP, and regulatory standards.
- Sponsor: Reviews and approves bioanalytical reports for regulatory submission.
- CRA: Verifies laboratory compliance during monitoring visits.
Accountability
The Bioanalytical Laboratory Head is accountable for assay accuracy, result reporting, and compliance with global regulatory requirements. The Sponsor is accountable for ensuring oversight and submission readiness.
Procedure
1. Sample Receipt
1.1 Verify chain of custody upon receipt of samples.
1.2 Record details in Sample Receipt Log (Annexure-1).
1.3 Store samples in validated freezers until analysis.
2. Method Validation
2.1 Validate all analytical methods before use in clinical trials.
2.2 Parameters include accuracy, precision, linearity, selectivity, sensitivity, stability, and recovery.
2.3 Maintain Method Validation Report in laboratory files.
3. Sample Preparation
3.1 Thaw samples at controlled temperature.
3.2 Process according to validated SOPs (protein precipitation, liquid-liquid extraction, SPE).
3.3 Record preparation details in Sample Preparation Log (Annexure-2).
4. Instrument Operation
4.1 Use validated instruments such as LC-MS/MS.
4.2 Calibrate daily and record in Equipment Calibration Log (Annexure-3).
4.3 Maintain instrument audit trails.
5. Calibration Curve and QC Samples
5.1 Generate calibration curve with at least 6–8 concentration points.
5.2 Include low, medium, and high QC samples in each run.
5.3 Results must be within ±15% of nominal values (±20% for LLOQ).
6. Data Review and Reporting
6.1 Analysts review raw data and generate run summary.
6.2 QA verifies accuracy and completeness.
6.3 Prepare Bioanalytical Report (Annexure-4).
6.4 Report results to Sponsor within timelines defined in protocol.
7. Repeat Analysis
7.1 Repeat analysis only if justified (e.g., sample integrity issue).
7.2 Document reason and obtain QA approval.
8. Deviations
8.1 Record deviations in Bioanalytical Deviation Log (Annexure-5).
8.2 Initiate CAPA for major deviations.
9. Archiving
9.1 Archive raw data, calibration curves, chromatograms, and reports in laboratory archives.
9.2 Retain documents as per regulatory timelines.
