How is a Urine or Blood Sample Tested in Florida?
The arresting officer or sometimes a probation officer can request a test for a urine sample. The official will usually submit a work request. Your attorney will check the form to see whether the officer requested testing for the presence of certain chemical or controlled substances.
The sample is then inventoried and your attorney can obtain the chain of custody form or forms. A urine test usually involves the following types of testing:
- a presumptive test using an immunoassay drug screen (ELISA); and
- confirmatory testing using Gas Chromatography and MassSpectrometryor (GC/MS) and sometimes LC/MS.
What is GC/MS for Urine Testing in Florida?
Gas Chromatography & Mass Spectrometry involves separating, identifying, and quantifying chemical or controlled substances. Many urine and blood tests for the presence of chemical or controlled substances involve the Gas Chromatography & Mass Spectrometry (GC/MS). By comping these two processes it reduces the possibility of error because it is less likely that two different molecules will behave in the same way in both the GC and MS.
What is Gas Chromatograph (GC)
- GC separates different components of a mixture into molecules by using a gas such as helium.
- GC identifies substances by the by time it takes to travel through the column.
- GC cannot differentiate between molecules that happen to have the same retention time.
Mass Spectrometer (MS)
MS bombards the molecules and fragments them. The time and quantity of breakup is recorded into a graph using a mass-to-charge ratio. MS requires a very pure sample. For MS testing, every substance has a distinct spectrum or pattern.
