Alcohol & Drug Analysis

BLOOD:

If you can get blood, that would be best for the alcohol determination reported as (grams per 100mL of alcohol).

NEW BLOOD INFORMATION
The DCI Laboratory has added the capability to analyze for cannabinoids in blood samples. Currently all blood samples, at the DCI Criminalistics Laboratory are being analyzed  for alcohol, inhalants,cannabinoids and amphetamines.    Refer to Private Laboratories Testing if analyses for other drugs in blood are needed. If so, the samples can be sent to a private lab at your agency’s expense.


The Cannabinoids, in blood samples, we are looking for:

delta9-tetrahydrocannabinol (THC)
11-hydroxy-delta9-tetrahydrocannabinol (a metabolite of THC)
11-nor-9-carboxy-delta9-tetrahydrocannabinol (a metabolite of THC)



The Amphetamines, in blood samples, we are looking for:

Amphetamine
Methamphetamine
Phentermine
3,4-Methylenedioxymethamphetamine (MDMA)
3,4-Methylenedioxyamphetamine (MDA)
3,4-Methylenedioxyethylamphetamine (MDEA)

Refer to Private Laboratories Testing if drugs are needed. These cases will need to be sent to a private lab at your expense for the analyses.

Alcohol analysis samples MUST be in a gray stoppered tube with:

  • 100 mg of Sodium flouride
  • 20 mg of Potassium Oxalate or some other equivalent preservative

Two results (grams/57mL) (grams/67mL) are reported when the urine sample is a first or random void. One result (grams/67mL) is reported when the urine sample is a 2nd void. Due to physiological variability, urine alcohol calculations tend to be rather conservative. Due to potential for production of alcohol post collections, urine sample storage (1% NaF) is critical.
