Cheap Paternity Test: What to Avoid
Published January 24, 2026 · Medically reviewed by the partner laboratory's medical director, AABB-accredited relationship-testing laboratory
A cheap paternity test under $80 usually signals fewer STR markers (16 vs 34), an unaccredited lab, or a hidden lab fee at mail-in. AABB accreditation, 34-marker STR analysis, and an all-in price under $110 are the honest markers of a legitimate at-home test.
The three cheap-test red flags
1) Fewer than 20 STR markers analyzed. 2) No AABB accreditation on the lab's own website. 3) A shelf price under $50 that requires a separate lab fee at mail-in.

Why marker count matters
16 markers still give a high probability, but 34 markers push certainty from 99.9% to 99.999999%+ and are the standard for court, USCIS, and Social Security.
The honest floor is $99
Below $99 all-in, either the lab is unaccredited, the marker count is low, or the cheap headline price hides a mail-in charge. $99 is the honest floor for AABB-accredited, 34-marker home testing.
