Description :
DFC occurs when an individual violates aspects of the law while under the influence of drugs. Biological samples collected after DFSA require comprehensive toxicology testing to identify the drug or drugs present. Unique factors and considerations include sample matrix, assay sensitivity, scope, and toxicological interpretation. Postmortem redistribution (PMR) refers to the changes that occur in drug concentrations after death. It involves the redistribution of drugs into the blood from solid organs such as the lungs, liver, and heart muscle. The anatomical location of blood sampling can affect drug concentration. The ideal site is the femoral vein constricted or clamped. Correlation with laboratory data and any available antemortem or antemortem clinical information is necessary to provide an adequate opinion on the cause of death.
