1. Drugs

2. - detect/ ID drugs in body fluid
- drug testing for potential employee, athlete, crime victims

3. Toxicology Testing and Procedures
clues help determine which tests to do - ex. syringe, bottles
TLC, GC, immunoassay - detect trace amounts of drugs in blood, urine, tissues
once narrowed --> confirmed w/ GC-MS

4. Reinsch Test heavy-metal poisoning
in HCl, metal ions produce silver colored coating on copper
if +, then use emission spectroscopy or atomic absorption spectroscopy to ID/confirm

5. Blood-Gas Screenings fire victims or cherry-red lividity
CO - use spectrophotometry or GC
if no CO in fire victim --> died before fire; set to hide evidence

6. Immunoassay relies on antigen-antibody response
antigen = substance that produces an immune response
antibodies produced in immune cells to attach to specific antigens
poisons/drugs = antigens

7. detects amount of antibodies in blood or urine when specific drug antigens added to sample
antigens & antibodies bond
Enzyme Multiplied Immunoassay Technique (EMIT) - detects certain drugs & their metabolites
ex. cocaine, marijuana, heroin, amphetamines, barbituates, etc
