34-Marker Paternity Test
Quick answer
Our standard test reads 34 STR markers — nearly double the industry minimum.
Where the AABB minimum is 15 markers, our lab reads 34. More markers increase the combined paternity index (CPI), reduce false inclusions in unusual populations, and produce clearer exclusions when a single marker is ambiguous.
