These are presumptive colorimetric test strips based on Tetramethylbenzidine (TMB) chemistry, producing a green-blue catalytic reaction upon contact with hemoglobin heme in bloodstains. The pre-prepared chemical strips/swabs exploit the catalytic peroxidase activity of blood hemoglobin acting on TMB, generating a distinct, intense green-blue color change within seconds of application. They offer high sensitivity, capable of detecting microscopic, latent, or diluted blood traces in both field and laboratory conditions.
