Wound blotting can be used to visualize the protein distribution on a wound bed through protein collection by attaching a nitrocellulose membrane to the wound surface. This study checked for consistency between the protein distributions determined by wound blotting and those determined by removal of the tissue. A patient who was planning to undergo surgical debridement of an ulcer in the sacral region that was caused by lying down for a long period after a cerebral hemorrhage was recruited in Fujisawa City Hospital, Kanagawa, Japan. Wound blotting was performed just prior to surgical debridement and the debrided tissue embedded in paraffin. The ulcer, which had a 2.9 cm major axis, was divided into 20 areas approximately 0.35 cm2 each, and the consistency of tumor necrosis factor-α positivity between the wound blotting samples and tissue sections was examined in each area. The sensitivity and specificity of wound blotting were 89% and 82%, respectively. This wound blotting method noninvasively revealed the protein distributions within the wound tissue.
