From: Quantitative criteria for improving performance of buccal DNA for high-throughput genetic analysis
ds/total DNA ratio threshold | N (%) of samples meeting threshold | Sensitivity | Specificity | Positive predictive value | Negative predictive value |
|---|---|---|---|---|---|
<0.34 | 23 (3.3%) | 20.5% | 98.7% | 65.2% | 90.5% |
<0.58 | 223 (34.0%) | 70.5% | 69.7% | 22.75% | 94.5% |
