Ebola Virus Real-Time Reverse Transcription–Polymerase Chain Reaction Results for Case 1
| Date Sample Taken (2014) | Specimen | Result (Cycle Threshold Value) |
|---|---|---|
| 9 September | Maternal blood | Positive (22.3) |
| 14 September | Maternal blood | Negative |
| 15 September | Maternal blood | Negative |
| 6 October | Vaginal swab after rupture of amniotic sac | Positive (28.9) |
| 17 October | Amniotic fluid | Positive (22.2) |
| 17 October | Placental swab | Positive (18.4) |
| 17 October | Cord blood | Positive (15.8) |
The lower the cycle threshold (Ct) value, the higher the virus load. A Ct value of 20 roughly corresponds to 108 EBOV RNA copies/mL of specimen.
Abbreviation: EBOV, Ebola virus.
