  • Publication number: 20150021205
    Abstract: A method of measuring lactate in a blood sample taken from capillary blood using a skin lancing procedure includes disposing onto an area of skin on an animal a predefined amount of a skin treatment compound that is capable of suppressing and/or eliminating and/or preventing and/or blocking any sweat from the skin in the area of a lanced wound site, the compound being disposed on the skin either before lancing the area of skin that provides a droplet of capillary blood for measurement of blood lactate concentration or after lancing the area of skin but before a droplet of capillary blood forms on the skin in order to prevent contaminating the blood sample, and then measuring the lactate concentration of the blood sample with a disposable lactate sensor strip.
