| Test | Result | No. of womena with test result (%) | Resolved patient infection statusb
|
|
|---|---|---|---|---|
| Positive | Negative | |||
| Cervical culture | Positive | 25 (5.8) | 25 | 0 |
| Negative | 409 (94.2) | 10 | 399 | |
| Urine LCRc | Positive | 32 (7.4) | 31 | 1 |
| Negative | 402 (92.6) | 4 | 398 | |
a
Four hundred eighty women enrolled; 434 had matching specimens.
b
Resolved patient infection status was defined as the resolved status of a patient with a positive culture or with a urine specimen positive by two tests (LCR, DFA staining, PCR OMP-1 gene, PCR plasmid gene, and LCR OMP-1).
c
After discrepant results were resolved, sensitivity was 88.6%, specificity was 99.7%, and positive and negative predictive values were 96.9% and 99.0%, respectively (sensitivity of culture, 71.4%).
