About Diatom Test

  • It helps in diagnosing the death caused by drowning. It tests diatoms in the body being tested.
  • Diatoms are photosynthesizing algae found in aquatic environment including fresh and marine waters, soils, etc., (almost anywhere moist).
  • If the person is alive when he enters the water, the diatoms will enter the lungs when the person inhales water while drowning.
  • These diatoms are then carried to different body parts by blood circulation.
  • If a person is dead when is thrown in the water, then there is no circulation and there is no transport of diatom cells to various organs.
  • Diatoms extracted from the body would be correlated with the samples from the water body where the drowning took place to ascertain the place of drowning.

  • The test will be negative if the person died instantly after falling into the water.
  • Diatom test is reliable unless the deceased person has been drinking water from the same source of water before his death.
