Accuracy
A comparison was conducted using the KET One Step Ketamine Test and GC/MS at 1,000 ng/mL cut-off. The following results were tabulated:| Method | GC/MS | Total Results | ||
| KET One Step Test | Results | Positive | Negative | |
| Positive | 10 | 8 | 18 | |
| Negative | 0 | 205 | 205 | |
| Total Results | 10 | 213 | 223 | |
| % Agreement | 100% | 96.2% | 96.4% | |
Analytical Sensitivity
A drug-free urine pool was spiked with Ketamine at the following concentrations: 0 ng/mL, 500ng/mL, 750 ng/mL, 1,000 ng/mL, 1,250 ng/mL and 1,500 ng/mL.The result demonstrates >99% accuracy at 50% above and 50% below the cut-off concentration. The data are summarized below:| Ketamine Concentration (ng/mL) | Percent of Cut-off | n | Visual Result | |
| Negative | Positive | |||
| 0 | 0 | 20 | 20 | 0 |
| 500 | -50% | 20 | 20 | 0 |
| 750 | -25% | 20 | 15 | 5 |
| 1,000 | Cut-off | 20 | 10 | 10 |
| 1,250 | +25% | 20 | 0 | 20 |
| 1,500 | +50% | 20 | 0 | 20 |
