Protein content (%) in different wound exudates derived from different collection methods compared with the DIN EN 13727:2009 standard test
| Method | Protein content (%) | |
|---|---|---|
| Mean ± SD | Median (min‐max) | |
| 24‐hour sponge method (n = 13)a , b | 1.85 ± 1.06 | 2.41 (0.32‐2.89) |
| Ultrasonic suspension (n = 11)a , b | 0.37 ± 0.55 | 0.19 (0.02‐1.96) |
| Vacuum exudate (n = 5)a | 1.00 ± 0.77 | 1.27 (0.08‐1.70) |
| Total | 1.14 ± 1.05 | 0.52 (0.02‐2.89) |
| Standard test: clean conditionsc | 0.03 (NA) | NA |
| Standard test: dirty conditionsc | 0.3 (NA) | NA |
Abbreviations: max, maximum; min, minimum; NA, not applicable.
a
For suspension tests, exudate was diluted at 1:10 ratio.
b
Two samples of wound exudate existed for patient No. 13, which were collected via 24‐hour sponge method and ultrasonic suspension.
c
According to DIN EN 13727:2009.
