Slough was a visible indicator of biofilm, which was the most available specimen from acute and chronic wounds. However, studies believed that slough were poorly accurate, and that the Levine swab was more recommended for sampling bacterial culture. This study aimed to compare slough with swab sample and analyze the consistency.

cohen's k coefficient of Gram Stain between Slough and Swap Specimens
compare the difference of Gram Stain after bacterial culture between Slough and Swap Specimens, by using statistics of cohen's k coefficient，values of κ from The κ coefficients in 0.81 to 1 waeres interpreted as excellentalmost perfect concordance, with 0.61 to 0.80 asrepresented substantial, 0.41 to 0.60 as mean moderate, 0.21 to 0.40 as fair, and 0 to 0.20 as slight.
Time frame: Day 0, patients' the first site in wound healing center
