Hiro Clinic aims for a testing accuracy (Paternity Confirmation Rate) of
99.99999999999% or higher.
This means that, with 8 billion people on Earth, the probability of a discrepancy is 0.008 people. This figure is derived from a statistical measure called the likelihood ratio, and achieving this level of accuracy is possible through the combined use of STR and SNP testing.
The Relationship Between Likelihood Ratio and Paternity Probability
| Likelihood Ratio | Paternity Probability | Error Rate |
| 10 | 90% or higher | 1 in 10 |
| 1,000 (three zeros) | 99.9% or higher (three nines) | 1 in 1,000 |
| 100,000 (five zeros) | 99.999% or higher (five nines) | 1 in 100,000 |
| 10,000,000 (seven zeros) | 99.99999% or higher (seven nines) | 1 in 10,000,000 |
| 1,000,000,000 (nine zeros) | 99.9999999% or higher (nine nines) | 1 in 1 billion |
| 100,000,000,000 (eleven zeros) | 99.999999999% or higher (eleven nines) | 1 in 10 billion |
| 10,000,000,000,000 (thirteen zeros) | 99.99999999999% or higher (thirteen nines) | 1 in 10 trillion |
STRs have a range of numerical distributions, allowing for more accurate identification.
To achieve this level of accuracy, more than 5,000 SNPs would be required if using SNPs alone.
