Frequently Asked Questions: DNA & Relationship Testing

 

​

​

1. Core Framework: Legal vs. Informational DNA Testing

 

What is the fundamental difference between a Legal and an Informational DNA test?

The primary difference lies entirely in the Chain of Custody protocol. A legal test requires an independent, certified third party—such as our certified technicians at EMS Proficient Mobile Phlebotomy Service—to verify government IDs, photograph participants, perform the sample collection, and securely log and ship the specimens using tamper-evident seals directly to the lab. An informational "peace of mind" test is collected at home without identity verification, meaning its results cannot be verified or used as evidence.

 

What makes a test legally admissible in a court of law?

To be legally admissible, the collection process must be structurally bulletproof against claims of fraud, sample-swapping, or tampering. It requires professional collection, verified identification records, continuous documentation (Chain of Custody), and analysis performed exclusively within an AABB-accredited laboratory infrastructure.

 

What types of legal matters require a Chain-of-Custody relationship test?

Chain of Custody testing is strictly mandated for:

  • Family Law Matters: Establishing legal paternity, child custody disputes, and child support orders.

  • Estate & Probate Litigation: Verifying biological next-of-kin for contested wills and inheritances.

  • Federal Applications: Meeting strict USCIS immigration visa requirements or processing Social Security next-of-kin benefit claims.

 

 

2. Prenatal Paternity Testing (NIPP / Certainty Test)

 

What is a Non-Invasive Prenatal Paternity (NIPP) test?

An NIPP test, commercially known as the Certainty test, is an advanced, highly accurate DNA-based method used to safely determine biological fatherhood before a baby is born. The process isolates free-floating cell-free fetal DNA (cffDNA) circulating naturally inside the pregnant mother's blood plasma and matches it against potential paternal genetic profiles.

 

What exact samples are required to execute a prenatal paternity test?

The test strictly requires a professional blood draw from the mother and a buccal (cheek) swab from the potential father. It is a biological impossibility to process this test using only the mother's blood, as the laboratory must have the alleged father's genetic profile to perform the comparative matching analysis.

 

Is a prenatal paternity test completely safe for the pregnancy?

Yes, it is 100% safe. Unlike older, invasive procedures such as amniocentesis or chorionic villus sampling (CVS) which carry an inherent risk of miscarriage, an NIPP test poses zero risk to the baby or the mother because it relies strikes exclusively on a non-invasive maternal arm blood draw and a paternal mouth swab.

 

How early into a pregnancy can an NIPP test be performed?

The test can be reliably and accurately administered as early as 7 weeks into the pregnancy, verified by gestational dating.

 

Are there any restrictions that prevent an NIPP test from being performed?

Yes. The test cannot be performed if the mother is carrying multiple fetuses (twins, triplets, etc.). This is because the laboratory cannot distinguish between the separate genetic profiles of multiple babies within a single maternal blood plasma sample.

 

 

3. Comprehensive Relationship & Kinship Diagnostics

 

What is Standard Paternity and Maternity DNA testing?

This is testing performed after a child is born using basic buccal (cheek) swabs from the child and the potential mother or father. It provides definitive proof of parenthood, delivering a probability of 0% if the individual is excluded, or 99.9% or higher if they are the biological parent.

 

What is Sibling DNA testing and when is it utilized?

Sibling testing is utilized when the alleged father or mother is deceased, missing, or uncooperative. By analyzing genetic markers shared between siblings, the lab determines a statistical likelihood score showing whether individuals share both parents (full siblings), one parent (half siblings), or no biological parents.

 

How do Grandparentage and Avuncular (Aunt/Uncle) tests work?

These tests reconstruct missing links in a genetic tree. When a parent is unavailable, the lab tests the child against biological grandparents, aunts, or uncles. Because these relatives share a predictable percentage of DNA with the missing parent, the lab can mathematically establish if the child belongs to that specific biological family line.

 

 

4. Lifestyle, Wellness, and Ancestry Analytics

 

What is a Lifestyle DNA test?

Lifestyle tests—such as Skin Care, Healthy Weight, and Food & Pet Sensitivity kits—are specialized, science-based tools processed by the DNA Diagnostics Center (DDC). They look at targeted genetic markers to identify your body's natural genetic predispositions and long-term metabolic tendencies to help optimize wellness routines.

 

Can a Food & Pet Sensitivity DNA test diagnose an emergency medical allergy?

No, this is absolutely not an allergy test. It tracks genetic sensitivities, baseline tendencies, and processing deficiencies—evaluating 30 specific genetic markers for nutritional or environmental irritants. It cannot detect or predict acute, life-threatening allergic reactions (such as anaphylaxis).

 

What is the GPS Origins Ancestry DNA Test?

The GPS Origins Ancestry DNA Test is a premium personal-use heritage tool that analyzes over 80,000 genetic markers to pinpoint precise geographic coordinates (towns, villages, or islands) where ancestral gene pools crossed paths. It maps historical migration routes stretching back roughly 1,000 years.

 

Can I use the GPS Origins test or other ancestry tests in a legal court proceeding?

No. Ancestry and lifestyle tests are strictly informational and lack a verified legal Chain of Custody. Because they are collected at home without professional identity verification, courts and child support agencies strictly reject them for legal matters.

 

 

5. Operational Logistics, Results, and Turnaround Times

 

What is the standard turnaround time for DNA results?

Once all required genetic samples are safely received at our partner AABB-accredited laboratory infrastructure, the standard testing turnaround time is 3 to 5 business days. Specialized testing like prenatal paternity can take up to 7 business days.

 

How do I arrange a professional mobile collection appointment?

EMS Proficient Mobile Phlebotomy Service removes all stress by coming directly to your home, legal office, or preferred private location. Our certified mobile phlebotomists verify identifications, capture photographs, perform the swabs or blood draws on-site, execute the Chain of Custody logs, and handle secure transport to the laboratory.
