Antemortem drowning means that the person was alive when he/she was submerged in water and subsequently died due to obstruction of airways by water i.e asphyxia. Diatoms are unicellular algae found in natural water bodies. If a person is alive when submerged in water then he/she inhales the water(containing the diatoms) and these then reach distant organs. This is not seen if person is already dead when submerged in water So, Positive Diatom test - Antemortem drowing Negative Diatom test - Postmortem drowning
