III. Labs: Drug Testing Methods
- 
                          General- Effectively deters use when combined with education
- Policy varies between NBA, NFL, and NCAA- NBA- Doctor must report players drug use to NBA

- NBA
 
- Gas Chromatography- Gold standard test but very expensive
- Used in playoffs and high level events
 
- Radioimmunoassay (RIA)- Lower cost test but higher rate of False Positives
- Used to test high school athletes
 
- 
                          Epitestosterone to Testosterone Ratio
                          - Assesses for Growth Hormone or Anabolic Steroid use
 
- Methods players use to counter drug testing- Probenecid blocks urine excretion of drugs
- False urine sample- Player instills another's urine into their Bladder
