This study explores the absorptive capacity of standard cotton wool-tipped swabs in vitro and in vivo. An alternative wound exudate sampling technique using small filter paper discs is also briefly examined. Results showed a poor uniformity of fluid absorption by swabs and a limited correlation of wound exudate quantities in relation to visual estimates and size of wound. It was found, however, that swabs reliably removed material from a wound surface. The filter paper technique appeared to offer no advantages.
