Abstract
|
|
|
For the diagnosis of drowning in immersed bodies, the diatom test has been controversial due to false-negative and false-positive results. Causes of false positive results include antemortem penetration of diatoms, and postmortem contamination during the submersion or the diatom preparation process.
Herein, we report a false-positive case in a 30-year-old woman who died from homicidal multiple stab wounds and was thrown into a shallow farm waterway approximately 10 days after her death. In addition, a discussion on the falsepositive diatom test results in immersed bodies with penetrating wounds is provided.
