PROTOCOLREFERENCE OUTLINE

Bioanalytical Method Validation Protocol

Validation protocol proving a method quantifies an analyte in the matrix it will actually see, under expectations that apply equally to nonclinical and clinical work. Covers selectivity against real interference, calibration and quality controls with the lower limit demonstrated rather than asserted, accuracy, precision and matrix effect across multiple lots, stability under every condition a sample will meet, and run acceptance and reassay rules fixed before any result is seen. Maps to ICH M10.

What a template is not

A template is a document baseline to adapt inside your own quality system. SPEQ does not approve, validate, or take responsibility for what you issue from it, and using one is not evidence of compliance.

PURPOSE

Bioanalytical method validation demonstrates that a method reliably quantifies an analyte in the matrix it will actually see. It is where nonclinical and clinical work meet, because the same harmonised expectations apply to both and the laboratory standard does not follow the study type. The frequent failure is validating in one matrix lot and one species, then analysing study samples that were never represented.

What's Inside

Analyte, matrix defined as species plus anticoagulant, and the concentration range the study will actually demand
Selectivity against real interference sources, including concomitant medication and haemolysed or lipaemic sample conditions
Calibration curve specification with the lower limit of quantification demonstrated by data rather than asserted
Accuracy, precision, matrix effect, recovery, dilution integrity and carryover, each with stated acceptance criteria
Stability covering every condition a sample meets from collection through storage to final analysis
Study sample analysis rules — run acceptance, reassay and repeat criteria — fixed before any run proceeds
Incurred sample reanalysis design, with the criterion and the response to a failure both stated

How to Use It

1Define matrix as species plus anticoagulant rather than simply plasma; a method used in another matrix needs a documented bridge
2Demonstrate the lower limit of quantification with data, rather than asserting it from the lowest calibrator you happened to prepare
3Assess matrix effect across multiple individual lots — a single lot misses the variability that later causes run failures
4Extend long-term stability to cover first collection through last analysis, including any storage the clinical site performs itself
5Fix run acceptance and reassay rules before results are seen, or every repeat decision becomes arguable after the fact
6Write the response to a failed incurred sample reanalysis into the protocol, not into the report that discovers it

REGULATORY CONTEXT

ICH M10 harmonises bioanalytical method validation and study sample analysis for nonclinical and clinical studies, covering selectivity, calibration, accuracy and precision, matrix effect, stability, carryover and incurred sample reanalysis, with the same expectations regardless of study type. It does not decide which range your study needs, which interferences are credible in your population, or when a partial validation suffices — those determinations belong to the laboratory and the sponsor. The protocol structure is SPEQ practitioner synthesis.
