Presumptive blood test using Hemastix® with EDTA in archaeology

Detecting early tattooing in the Pacific region through experimental usewear and residue analyses of obsidian tools

“…In the six cases where they were applied (SE-SZ-8#656, SE-SZ-8#690, SE-SZ-8#681, SE-SZ-8#689, SE-SZ-8#857, SE-SZ-8#860), the presumptive chemical test, Hemastix © , yielded positive reactions for blood (cf. Matheson and Veall, 2011;Garling, 1998;Loy, 1983).…”

Evidence for Pleistocene seed grinding at Lake Mungo, south‐eastern Australia

“…Fatty acids were detected by a method (Cu-TEA/ CPC) developed by Falholt and Lund (1973). Hemastix® strips were used to detect hemoglobin (Matheson & Veall 2014) and iodine potassium iodide (IKI) was used to detect starch (McCready & Hassid 1943). These tests were selected to canvas the range of plant and animal residues.…”

Hemoglobin assay for validation and quality control of medical device reprocessing

“…We advise multiple sample point averaging and regular Highly specific 3.3 ng 12 ng/cm 2 calibration with a standard to ensure accurate results. In addition to evaluating medical device reprocessing, the assay may have application in forensics [16] or archeology [8] if a sensitive and quantitative Hb assay is needed for the sake of minimizing error sources, calculating the statistics of measurement variability, determining cutoffs, etc. Future work may lead to the development of a simple, portable Hb assay which can be extremely valuable both in the field and in the central processing lab.…”

“…We modified blood test strips to fit 96-well microplates and optimized the use of a plate reader to measure reflectivity change caused by hemoglobin. The blood test strips operate on the principle of a redox reaction by the heme group in hemoglobin with hydrogen peroxide and 3,3′,5,5′-tetramethylbenzidine (TMB) [8]. TMB is oxidized to form a diimine which produces a blue color shift.…”
