Types of Drug Testing
  • Baseline testing for new patients
  • Monitor the use of elderly patients’ medications
  • Investigating change in patient’s behavior
  • Pain Management and compliance testing
  • In-patient or out-patient drug treatment facilities
  • Juvenile group home patient monitoring
  • Medically necessary testing (pre-surgery, toxicity/overdose cases, etc.)

Why Testing is Important
Many medicines prescribed for pain are poorly managed, taken incorrectly, not taken at all, abused or sold for profit. Many patients are taking other drugs that they forget to tell their physician or do not want to tell their physician. These include both prescription and illicit drugs. It is recommended that patients be monitored for prescribed and non-prescribed drugs through routine, periodic testing. This testing can determine the absence/presence of drugs or their metabolites.

Types of Drug Testing
Drug Screen

The first is the drug screen, which gives a qualitative (positive or negative) result. These tests are quick and cheap but have disadvantages.

  1. Drug screens do not indicate what drug is present, only what class.
  2. False positive or false negative results are likely due to a lack of sensitivity and specificity.
  3. False positive results can occur if something in the sample is chemically related to the target.
  4. Not all drugs can be screened.

Confirmation Test
The second is the confirmation test. These quantitative tests are more sensitive and have higher accuracy. They provide an amount in the system. They determine if a drug is present that was not picked up by the screening method (false negative) and what type of drugs caused the positive screen results. They also allow to see how the drug is metabolized. This allows the physician to determine whether the patient is compliant with their treatment plan and protects the patient from being given medications that would interact with the medicine that they are currently taking.
