Comparison of ratios of intensities for bands near 1625 cm−1 (α), 1456 cm−1 (β), and 1075 cm−1 (γ), and new bands observed in ATR-FTIR spectra of UTI.
| Rα:Rβ:Rγ (a) | ΔRα:ΔRβ:ΔRγ | New Bands/cm−1 | WBC/HPF (b) | |
|---|---|---|---|---|
| IRav/non | 100:45:30 | 0:0:0 | - | <5 |
| No. 1 (E. faec.) | 100:33:28 | 0:−12:−2 | 1771, 1396, 1310 | 6–10 |

| No. 3 (yeast) | 100:33:30 | 0:−12:0 | 1771, 1405 | 20–29 |
| No. 4 (yeast) | 100:37:28 | 0:−8:−2 | 1774, 1541, 1398, 1312 | >100 |
| No. 5 (E. coli) | 100:36:31 | 0:−9:+1 | 1396 | 20–29 |
| No. 6 (yeast) | 100:44:53 | 0:−1:+23 | 1033, 992 | 50–99 |
| No. 7 (P. aerug.) | 100:53:35 | 0:+8:+5 | 1772, 1397, 1311 | >100 |
(a) The intensity of the band near 1625 cm−1 (α) was assigned a value of 100; the ratio values of bands near 1456 cm−1 (β) and 1075 cm−1 (γ) were then calculated from their intensities relative to the band near 1625 cm−1 (α). (b) WBC/HPF: white blood cell (leukocyte)/high-power field.
