Hair Follicle Drug Test

In recent years the method to conduct drug testing has more frequently included a hair follicle drug test. Many employers, courts and Substance Abuse Professionals are requiring a hair follicle drug test instead of a standard urine test. Hair follicle drug tests are used by employers who have zero-tolerance drug use policies, courts and individuals on probation. The primary benefit of a hair follicle drug test includes a much longer detection period for drug use which typically is up to 90 days. However, when screening drug use within the last 5 days the urine test continues to be the most accurate test.

Hair Follicle Drug Test Process

The procedure used to perform a hair follicle test is simple, the drug testing specialist will cut approximately 120 strands of hair (not really a lot) utilize a chain of custody procedure and send the hair to a certified laboratory for analysis. Drug testing centers require at least 1.5 inches of hair to perform this test and the hair generally needs to come from the head, however if the donor does not have head hair certain testing centers can use hair from chest, leg or arm pit.

If a donor has no hair on their body, than a hair test cannot be performed!

Hair Follicle Drug Test Results

Once the hair follicles have been analyzed by a certified laboratory they will then be reviewed and then verified by a Medical Review Officer (licensed Physician) who will than release the results. Generally a negative hair follicle drug test result is available in 2-3 days. A non-negative hair follicle drug test is available in approximately 5 days.

Urine cut-off levels are expressed in nanograms per milliliter (ng/mL) or as a weight of drug per unit volume of urine. Hair cut-off levels are expressed in picograms per milligram (pg/mg) or as a weight of drug per unit weight of hair

Rockville, along with neighboring Gaithersburg and Bethesda, is at the core of the Interstate 270 Technology Corridor which is home to numerous software and biotechnology companies as well as several federal government institutions. The city also has several upscale regional shopping centers and is one of the major retail hubs in Montgomery County.

Situated in the Piedmont region and crossed by three creeks (Rock Creek, Cabin John Creek, and Watts Branch), Rockville provided an excellent refuge for semi-nomadic Native Americans as early as 8000 BC. By the first millennium BC, a few of these groups had settled down into year-round agricultural communities that exploited the native flora, including sunflowers and marsh elder. By AD 1200, these early groups (dubbed Montgomery Indians by later archaeologists) were increasingly drawn into conflict with the Senecas and Susquehannocks who had migrated south from Pennsylvania and New York. Within the present-day boundaries of the city, six prehistoric sites have been uncovered and documented, along with numerous artifacts several thousand years old. By the year 1700, under pressure from European colonists, the majority of these original inhabitants had been driven away.
