Definition

Buccal swab

A buccal swab is a non-invasive DNA collection method using a sterile cotton-tipped applicator rotated against the inner cheek. It captures epithelial cells that contain a complete copy of the participant's DNA. The procedure is painless, takes about 30 seconds per swab, and is safe for all ages including infants.

How accurate are paternity tests?

DNA paternity tests at AABB-accredited laboratories achieve 99.99% accuracy when the alleged father is the biological father (inclusion) and 100% accuracy when he is not (exclusion). Accuracy is achieved through the analysis of 20+ STR genetic markers and is consistent across legal, at-home, and prenatal testing methods.

Definition

Chain of custody

Chain of custody is the documented protocol that proves DNA samples were not tampered with between collection and analysis. It includes verified participant identity, witnessed sample collection, tamper-evident packaging, signed transfer logs, and AABB-accredited laboratory handling. Chain of custody is what makes a paternity test admissible in court.

How long do results take?

Standard paternity test results are available in 1 to 3 business days from sample receipt at the laboratory. Rush 24-hour processing is available for court deadlines and other urgent situations for an additional fee. Prenatal NIPP results take 5 to 7 business days due to the additional fetal-DNA isolation steps.

Paternity test accuracy at AABB-accredited laboratories is 99.99% for inclusion and 100% for exclusion, achieved through the analysis of 20+ STR genetic markers. Results are typically delivered in 1 to 3 business days.
