34 vs 16 Markers
Quick answer
More markers = more certainty. Our 34-marker test is 2x the industry minimum.
Drugstore paternity tests read 15–16 STR markers. Our lab reads 34. Doubling the marker count increases the CPI by many orders of magnitude and makes ambiguous results essentially impossible.
