Accurate and Reliable Results:

  • High Precision:

  • Surety DNA achieves high accuracy and reliability in their results through a series of well-established scientific and procedural steps. Our paternity tests are conducted with cutting-edge technology and rigorous standards, ensuring over 99.99% accuracy in results. You can trust the outcome to be precise and dependable. Here’s an overview of how we ensure accuracy and reliability:

    1. DNA Collection and Handling

    Sample Collection:

    • A buccal (cheek) swab is primarily used for DNA collection. It is non-invasive and provides high-quality DNA.

    • A blood sample is collected from the maternal parent for the Non-Invasive Prenatal Test

    Chain of Custody:

    • To maintain the integrity of the sample, a strict chain of custody is followed, for legal cases each step is carefully documented.

    • This involves documenting the collection, transfer, and storage of the sample to ensure it has not been tampered with or contaminated.

    2. DNA Extraction and Analysis

    Extraction:

    • DNA is extracted from the collected cells using standardized chemical processes that ensure high purity and concentration of DNA.

    • Through the use of a PCR Amplification: Polymerase Chain Reaction, which the DNA is amplified to allow for the analysis of specific DNA regions.

    Short Tandem Repeats Analysis:

    • STRs are specific areas of DNA that vary greatly among individuals.

    • 15-20 STR loci are analyzed. The more loci tested, the higher the accuracy.

    • These loci are compared between the alleged father and the child.

    3. Matching and Statistical Analysis

    Comparison:

    • The STR profiles from the child and the alleged father are compared.

    • Each locus will have two alleles, one inherited from the mother and one from the father.

    Probability Calculation:

    • The likelihood ratio or probability of paternity is calculated using population genetics.

    • A Probability of Paternity (POP) is then determined. A POP of 99.99% or higher is typically considered conclusive for paternity.

    4. Quality Control and Accreditation

    Quality Assurance:

    • Our partnered Laboratories follow stringent quality control protocols to prevent errors, this includes duplicate testing and blind sample testing.

    • Controls and standards are always included in every test batch to ensure reliability.

    Accreditation:

    • Our Partnered Laboratories are accredited by the American Association of Blood Banks (AABB)

    • This accreditation ensures our labs adhere to high standards of testing accuracy, reliability, and ethical practices.

    5. Reporting

    Result Reporting:

    • Results are always reviewed by multiple qualified scientists before being reported.

    • Your final report clearly states the probability of paternity and includes the profiles of the tested individuals.
