Standardized DNA collection card protocols for paternity testing ensure accurate, legally valid样本采集, critical for resolving biological parentage claims. These protocols govern sample handling from collection to lab analysis, minimizing errors and contamination.
Core Protocols
-
Pre-Collection Prep: Use sterile, FDA-approved collection cards; obtain informed consent; verify participant IDs (photo ID for legal tests).
-
Sample Collection: For oral swabs—rub sterile swab on inner cheek 10–15 times, apply to card; for blood—spot 2–3 drops of capillary blood. Air-dry 1–2 hours.
-
Labeling: Mark cards with unique ID, participant name, DOB, collection date/time, and collector initials.
-
Storage/Transport: Seal in moisture-proof bags with desiccants; ship at room temp; avoid extreme heat/moisture.
-
Quality Control: Check card integrity pre-use; document any sample anomalies (e.g., insufficient volume).
Key Features
-
Legal Validity: Aligns with ISO 17025, AABB standards for court-admissible results.
-
Contamination Control: Single-use tools, gloves, and sealed packaging prevent cross-contamination.
-
Accuracy: Standardized sample volume and handling ensure reliable DNA profiling.
-
Convenience: Portable cards enable collection in clinics, homes, or remote locations.
Scope & Applications
-
Legal Paternity Cases: Child support, custody, inheritance disputes requiring court-admissible evidence.
-
Private Paternity Testing: At-home or clinic-based tests for personal confirmation.
-
Immigration Applications: Proving biological relationships for visa/passport processes.
-
Adoption/Ancestry: Reuniting adoptees with biological parents via DNA matching.
