Drug and Alcohol Tests

What is a Drug & Alcohol Test?

An analysis of a biological sample such as urine, hair, saliva, breath or blood to detect the presence of specific drug groups including ethanol (alcohol). The analysis determines prior drug and alcohol use. The drug test is performed to detect illegal drug use, abuse of prescription drugs or the use of performance enhancing drugs for sport. The alcohol test is performed to determine alcohol use, evidence of abstinence or chronic alcohol abuse.

Please see below for the Drug and Alcohol Testing services provided by Crystal Health.

The urine instant Point of Care (POC) Drug Test indicates the potential presence of drugs of abuse using tried and trusted immunoassay screening analysis.

This test option is a cost effective and prompt method of determining recent drug use and screening results are available within minutes of the sample being collected.

The Standard Urinalysis Panel of 6 drug groups is listed below. Various additional drug groups can be tested upon request and the POC Test can be combined with a Breathalyser or Alcohol Saliva Screen to meet your testing requirements.

  • Cocaine
  • Amphetamine
  • Benzodiazepine
  • Cannabis
  • Methamphetamine
  • Opiates

Certification to ISO 9001 and ISO 13485 ensures that the devices are manufactured and distributed with a quality-focussed approach. For increased quality assurance, the drug test cup is CE Marked in accordance with 98/79/EC.

Depending on your requirements, additional drugs can be tested using this method, these include:

  • Barbiturates
  • Phencyclidine
  • Propoxyphene
  • Methadone
  • Ketamine

The analysis is performed against predefined cut-off levels for all drugs tested. The link to the table below details this information, this will assist you in your decision for the correct test for your circumstances.

The test is performed under strict chain of custody protocols by fully trained and certified sample collection officers. In addition, each Test Donor is legally identified at the appointment. The test is available at Crystal Health network of UK Drug Testing Clinics or via the mobile collection service.

Additionally, all administration including the test results process is performed in compliance with ISO 9001, ISO 27001 and ISO 14001. POC test results are provided at the appointment to the donor and the donor’s organisation if applicable.

The Urine Laboratory Screen & Confirmation Drug and Alcohol Test confirms the presence of drugs of abuse using UKAS 17025 accredited laboratory immunoassay screening and GCMS confirmation testing methods.

This Drug test option is an effective and accredited method of determining recent drug use, with initial screening results being available within 2 working days of sample collection.

If required, confirmation testing of non-negative screen results are available within a further 3 to 5 working days.

The Standard Urinalysis Panel of 8 drug groups is listed below which includes the testing of alcohol as standard if required.

  • Alcohol
  • Amphetamines, including Methamphetamine and Ecstasy (MDMA)
  • Barbiturates
  • Benzodiazepine (including Diazepam and Temazepam)
  • Cannabis
  • Cocaine
  • Methadone
  • Opiates

Additional drug groups can be tested upon request and the Laboratory test can be combined with a Breath Alcohol Screen to meet your testing requirements.

Each Donor is legally identified at the appointment. Urine samples are then collected, sealed and bar coded to strict Chain of Custody Protocols. Samples are then processed to our UKAS 17025 and ILAC accredited laboratory, where an initial screening drug test is performed. The laboratory screen uses highly accurate CEDIA reagents, a considerable advantage over the alternative urine instant Point of Care (POC) Drug Test.

Depending on your requirements, additional drugs can be tested using this method, these include:

  • Buprenorphine
  • Ketamine
  • LSD
  • Methaqualone
  • Phencyclidine
  • Propoxyphene

The analysis is performed against predefined cut-off levels for all drugs tested. The link to the table below details this information, this will assist you in choosing the correct test for your circumstances.

The test is performed under strict chain of custody protocols by fully trained and certified sample collection officers. The test is available at Crystal Health network of UK Drug Testing Clinics or via the mobile collection service.

Laboratory reports are generated and issued for all samples that screen negative. Initial screening takes up to 2 working days from the appointment, however, reports are usually available the day following sample collection.

Samples that screen non-negative are issued with a ‘Undergoing Further Analysis’ report and require additional Confirmation Testing. Confirmation Testing is required to identify the drug or metabolite found in the sample and the quantity present.

Any sample which contains the presence of a drug or metabolite over the cut-off level, will be issued as a positive laboratory report, providing evidence of abuse. Dependant on the circumstances, the laboratory report may specify whether the drug and its quantity can be deemed therapeutic i.e. in line with declared medication. Further investigation to confirm this can be undertaken by utilising Crystal Healths Medical Review Service.

All administration including the test results process is performed in compliance with ISO 9001, ISO 27001 and ISO 14001. All laboratory reports are provided in secure PDF format via email.

The Oral Fluid Laboratory Screen & Confirmation Test confirms the presence of drugs of abuse using UKAS 17025 accredited laboratory immunoassay screening and GCMS confirmation testing methods.

The Hair test is performed in a UKAS 17025 Accredited laboratory and provides the most reliable and accurate form of historical drug use.

The Hair test analyses the drugs and metabolites found inside the hair strand. When a drug is ingested it enters a person’s blood stream, it then transfers from the blood vessels into the hair shaft at the root.

Hair can be taken from anywhere on the head or body, however we recommend that head hair is used due to biological factors that influence hair growth rate.

Regardless of the hair origin, only a moderate amount of hair sample is required for the analysis. This means that the area from which the hair has been collected is normally unnoticeable.

Hair Testing can be used to show the level of drug use over a specific period-of-time, or provide evidence of abstinence from 1 month to 12 months, depending on the length of hair available.

Segmentation of the hair sample is also possible to provide a month by month view of potential drug use. This would also support a claim that someone had recently stopped taking drugs. This is possible in increments of 1cm or 0.5cm segments. Other options are also available for certain circumstances such as spiking incidents. This can be discussed with a Clinical Advisor at the time of booking.

The Hair Alcohol laboratory test provides an accurate analysis of longer term alcohol intake for upto 6 months.

As hair grows, it absorbs the metabolites of alcohol, Fatty Acid Ethyl Esters (FAEEs) and Ethyl Glucuronide (EtG) into its structure.

A Hair test will look at the amount of each metabolite found in the hair sample, to indicate the level of alcohol consumption for the required time period, up to the previous 6 months.

The FAEE finds its way into the hair mainly by diffusion from an external sebum layer. This is an oily substance secreted by glands in the skin.

Long term excessive consumption of alcohol would cause an elevated FAEE result, if the amount of FAEE detected in the hair sample is above the cut off level of 750pg/mg (picogram per milligram), this suggests that alcohol has been consumed at a chronic level.

The FAEE is used alongside the EtG analysis to give the best overview of a person’s alcohol consumption, as both can be affected by environmental factors. EtG is formed in the liver, and is only produced when alcohol has been consumed, the EtG is then deposited into the hair mainly from sweat.

A higher level of EtG being detected in the hair illustrates that more alcohol has been consumed, the reporting guidelines are as follows:
Example of EtG Interpretation

If the EtG is lower than 7pg/mg, this is suggestive of abstinence within the period covered by the sample.

If the EtG is between 7 – 30pg/mg, this is indicative of alcohol use within the period covered by the sample.

If the EtG is over 30pg/mg, this is suggestive of chronic excessive alcohol use within the period covered by the sample.

Each Drug Test Donor is legally identified at the appointment. hair samples are then collected, sealed and bar coded to strict Chain of Custody Protocols by a fully trained & certified sample collection officer. Samples are then processed to our UKAS 17025 and ILAC accredited laboratory, where the test is performed.

The test is available at selected Crystal Health network of UK Drug Testing Clinics or via the mobile collection service.

The analysis for a Hair test takes 3 – 5 working days from receipt of your sample.

The fully accredited sample collection process and laboratory analysis ensures that all test reports issued are legally defensible.

It is recommended that a Blood Alcohol test is performed in combination with the Hair test to give the most accurate analysis of a person’s alcohol consumption.

We also recommended that an Expert Witness statement is requested to give a further understanding of the test report, this can be discussed at the time of your booking.

All administration including the test results process is performed in compliance with ISO 9001, ISO 27001 and ISO 14001.
