Copies of wild-type cfDNA per mL of CSF were calculated
| Sample | Wild-type |
Mutant |
Number of probes tested | ||||
|---|---|---|---|---|---|---|---|
| Copies/mL of CSF (mean) | Estimated ng/ mL of CSF | Standard error | Copies/mL of CSF (mean) | Estimated ng/ mL of CSF | Standard error | ||
| Case 1 | 2304 | 7.81 | 317 | 76 | 1.14 | 76 | 5 |
| Case 2 | 201,100 | 603.3 | - | 0 | 0 | - | 1 |
| Case 3 | 33,493 | 100.48 | 1258 | 0 | - | - | 3 |
Patient 1, 2, and 3 had 2604, 201,100, and 33,493 wild-type copies per mL of CSF respectively. A small amount of mutant DNA was detected in case one in one of five probes
