What Are the Different Types of Drug Tests?
There are four primary types of specimen sample used for testing purposes: urine, hair, saliva, and blood. The most common form of drug testing is by urine test which has the benefit of being inexpensive and generally accepted in the drug testing industry.

Urine Tests

• Are the least expensive of the test methods
  
• Can be done at home
  
• Detection period primarily within the past week
  
• Can be affected by abstaining from use for a period of time before the test
  
• Are often temperature tested to insure sample integrity

Hair Tests

• Are considered the least intrusive method of drug testing
  
• Are currently significantly more expensive than urine tests
  
• Detects substance use over a longer period of time
  
• Do not usually detect use within the past week
  
• Test positive a little more than twice as often as a urine test
  
• Are not significantly affected by brief periods of abstinence from drugs
  
• Can sometimes be used to determine when use occured and if it has been discontinued
  
• Claims to be able to reliably differentiate between opiate and poppy seed use

Saliva Tests

• Can be done at home (for example by parents)
  
• Detect use primarily within the past week (longer with regular use)
  
• Can be affected by abstaining from use for a period of time before the test

Blood Tests

• Are considered the most intrusive method of testing
  
• Are the most expensive method of testing
  
• Are the most accurate method of testing
  
• Are the least common method of testing (most likely due to cost)
