Paternity Testing

Establish a biological relationship between a father and child.

Types of Paternity Tests Offered:

  • Peace of Mind Testing: Private results for your personal knowledge.
  • Legal Paternity Testing: Results admissible in court for child support, custody, or other legal matters.

How It Works:

  • Non-invasive cheek swab from both the child and the alleged father.
  • Quick, painless, and collected at your location.

Preparation:

  • Do Not Eat or Drink: Avoid eating, drinking, chewing gum, or smoking at least 30 minutes prior to your appointment.
  • Infants: If the test is for an infant, please avoid giving breast milk at least 2 hours prior to the test, as breast milk can transfer the mother's DNA to the infant, which may affect the test results.
  • Bring a Valid ID: Please have a government-issued photo ID (such as a driver’s license or passport) for verification purposes.

Accurate. Confidential. Court-Admissible.

Whether you need answers for personal peace of mind or legal purposes, our paternity DNA tests provide fast, reliable results you can trust.
We can come to you — offering mobile, discreet, and professional collection services.

Missing Father Paternity Testing

Confirm Biological Relationships When the Father Is Unavailable.

When the alleged father is missing, unavailable, or unwilling to participate in paternity testing, Onsite Labs offers alternative DNA testing options to establish biological relationships.

These tests help provide peace of mind and can be used for legal purposes such as custody cases, inheritance rights, immigration, or social security benefits.

Who Might Need This Test?

  • Individuals seeking child support or custody without the father's cooperation
  • Families needing proof of relationship for immigration purposes
  • Relatives wanting confirmation for estate or inheritance claims
  • Adults seeking peace of mind about biological relationships


Types of Tests Offered

🔹 Grandparentage DNA Testing
Determines if an individual is biologically related to the alleged father’s parents (grandparents).

Ideal when one or both paternal grandparents are available.

🔹 Siblingship DNA Testing
Evaluates whether two individuals share one or both biological parents.

Used when testing brothers, sisters, or half-siblings.

🔹 Avuncular DNA Testing
Confirms the biological relationship between an individual and the alleged father’s full sibling (aunt or uncle).

Best when grandparents are not available but an aunt or uncle is.

How the Process Works:

  • Sample Collection
    • A simple, non-invasive cheek swab is collected from each participant.
    • Our mobile team can come to your home, business, or agreed location.
    •  Please arrive on time and do not eat, drink, or smoke 30 minutes before your cheek swab collection.
  • Laboratory Testing
    • Samples are sent to an accredited DNA testing laboratory.
    • Results are available within 2–5 business days.
  • Results
    • We provide clear, easy-to-read reports.
    • Legal documentation available if needed for court or official use.

Preparation:

  • Do Not Eat or Drink: Avoid eating, drinking, chewing gum, or smoking at least 30 minutes prior to your appointment.
  • Infants: If the test is for an infant, please avoid giving breast milk at least 2 hours prior to the test, as breast milk can transfer the mother's DNA to the infant, which may affect the test results.
  • Bring a Valid ID: Please have a government-issued photo ID (such as a driver’s license or passport) for verification purposes.
