ABH Typing on Formaldehyde Fixed Saliva Stains

Öz

Fifty saliva stains of known blood group and secretor status were prepared on two different substrates (cotton and terrycot) and examined for the presence of ABH specific substances by absorption-inhibition and absorption-elution after fixation with formaldehyde (10 per cent). The absorption-elution technique showed higher percentage of correct results (after fixation with 10% formaldehyde) as compared to absorption-inhibition and is more sensitive and effective in preserving the water soluble substances. The type of substrates did not influence the results to an appreciable extent.
