Determining the biological relationship between individuals requires a precise selection of testing protocols. Selecting the incorrect kit can lead to inconclusive results or avoidable delays. Use this clinical guide to identify the specific DNA service required for your circumstances.
What is your primary objective?
Identify the relationship you intend to verify. The most common requirement is establishing paternity, but alternative biological markers are necessary if the alleged father is unavailable.
- To confirm a biological father: Select the DNA Paternity Test Kit.
- To confirm a biological mother: Select Maternity DNA Testing.
- To verify siblings share one or both parents: Select the Sibling DNA Test Kit.
- To confirm biological grandparents: Select the Grandparentage DNA Test Kit.

Is the alleged father available for testing?
The availability of the alleged father dictates the technical approach of the laboratory. Direct comparison is always the preferred clinical standard.
- Father is available: Standard buccal (cheek) swabs provide 99.9% accuracy for inclusions.
- Father is unavailable: Utilize indirect lineage testing. If the father is deceased or absent, test his biological parents or siblings. Use the Aunt/Uncle DNA Testing Kit or the Y-Chromosome DNA Testing Kit for male-line verification.
Are you currently pregnant?
Biological certainty is achievable before birth. If the mother is at least seven weeks pregnant, do not wait until delivery to establish paternity.
- Requirement: Prenatal Testing. Use the NIPP Plus Testing Kit. This non-invasive prenatal paternity test analyzes cell-free fetal DNA found in the mother’s blood. It poses zero risk to the pregnancy.
Is the test required for legal proceedings?
Determine if your results must stand in a court of law or for government applications.
- Legal/Official Use: If the results are for child maintenance, inheritance, or the Home Office, you must order a Legal DNA Testing Kit. These require a strict chain of custody and professional sample collection.
- Peace of Mind: For personal knowledge, a standard home kit is sufficient.
