Standardized DNA blood sample collection procedures are crucial in ensuring the accuracy and reliability of paternity testing. Proper sample collection, handling, and storage are essential to avoid contamination and maintain the integrity of the DNA for accurate results.
Collection Procedures:
-
Patient Identification: Properly verify the identity of the individuals involved in the paternity test to avoid mix-ups.
-
Collection Method: Use sterile, single-use blood collection cards or tubes. Collect blood samples with minimal handling to prevent contamination. For consistency, use standardized equipment and techniques.
-
Labeling: Clearly label all samples with the participant’s name, date, and any other identifying information to prevent misidentification.
-
Preservation: Immediately dry blood samples on the collection card, if applicable, to preserve DNA integrity. Store the samples in a cool, dry place until transport.
-
Transport and Submission: Transport the samples securely and promptly to the testing laboratory, following chain-of-custody procedures.
Key Features:
-
Accurate Results: Standardized procedures ensure reliable DNA extraction and analysis, minimizing errors.
-
Consistency: Following uniform procedures across different locations ensures consistency in results, regardless of where the sample is collected.
-
Minimized Contamination Risk: Strict adherence to sterilization protocols reduces the chance of cross-contamination between samples.
Scope:
These standardized procedures are used in forensic paternity testing, legal cases, family disputes, and genetic research, ensuring fair and accurate results.
