Specimen Requirements  

Urine: 30 ml random urine (5 ml min). Addition of Sodium Fluoride preservative is required.


Method of analysis include Gas Chromatograph, Gas Chromatograph Mass Spectrometry (GC/MS) ONLY. This is highly accurate and sensitive that produces results with 100 confidence.  Additionally, it is highly recognize in court as the "Gold" standard in analytical testing of drug compounds.

Alcohol (Ethanol Analysis)

Ethyl Alcohol or Ethanol is an organic compound found in alcoholic beverages such as beer, liquor or wine.  The of analysis of Ethanol is ideal for DUI/DWI case or suspected alcohol consumption, whereby alcohol analysis is required that may have legal implications. The specimen of whole blood is usually preferred as this gives the true level of alcohol. Serum may also be used. However, the alcohol level is between 16%-18% higher than whole blood. A urine specimen is also acceptable.

1. Whole Blood: 5 ml whole blood.  Use lavender top tube with Sodium Fluoride (NaF) preservative.
2. Serum or Urine; 3.0 ml serum or 15 ml urine with Sodium Fluoride preservative.

FEE  (Blood, serum, or urine) - $345.00 per sample per specimen type (blood, serum, or urine.

Glucose Analysis - $275.00 per sample.  Highly recommended.  Why test for glucose?  Glucose is a sugar that is broken down to ethanol alcohol, that can contribute to the overall concentration of Blood Alcohol (BAC).

Method: Gas Chromatograph Flame-Ionization Detection (GC-FID).

Quantitative Weight Measurement of Drug(s)

     Often times, illegal substances of Cocaine, Marijuana, and others are found during search and seizure or simply through a routine traffic violation stop. 
     To verify that the weight of a found substance (i.e. Cocaine, Marijuana, etc.), re-weighing is an important task.   In doing this, a qualitative and/or physical weight measurement of the alleged substance can be done.  If the substance has already been identified, physical weight measurement or re-weighing is usually done.
