November 26, 2024

Drug Testing in Pakistan has become a crucial practice across various sectors to monitor the abuse of controlled drugs. This procedure is used to identify the presence of prescription or illegal substances in the human body. 

Drug testing plays a critical role in maintaining public health and safety, from workplaces to law enforcement working to restrict drug-related crimes. If you want to know a drug test, its procedure, and which lab you can trust for drug testing in Pakistan, read on.

So, let’s get into it!

What Is a Drug Test?

A drug test uses a biological sample such as hair, blood, or urine to detect a legal or illegal drug in a human’s body. Drugs include legal and illegal substances such as tobacco, alcohol, prescription medications, over-the-counter medications, and controlled substances. These tests are performed in various settings for different purposes using various techniques.

Purpose of Drug Testing

Workplace Safety:

Workplace Drug Testing is a common practice for pre-employment and random screening to ensure a safe workplace culture. These tests are conducted annually, biannually or on suspicion as per the company policies. It helps organizations meet legal obligations, maintain employee wellness, and build trust in corporate dealings.

Medical Diagnosis:

In medical diagnosis, these tests are used to monitor prescribed drug use and find out any potential drug interactions.

Law Enforcement and Legal Compliance:

Legal compliance is another useful purpose of drug screening and testing procedures to address criminal investigations or drug-related crimes.

Drug Testing Procedure

Consent through Form:

At Chugthai lab, we ensure a simple testing procedure that starts with obtaining the individual’s consent via a form and disclosure of prescription medicine, if any. 

Witnessed Sample Collection:

Our trained professionals carefully collect the required sample—whether blood, hair, or urine—adhering to strict protocols designed to ensure accuracy and prevent contamination.

Sealed Sample and Chain of Custody Documentation:

The collected sample is sealed and labeled before being transported. This sealed sample then undergoes a chain of custody documentation process to ensure integrity.

Analysis and Report Generation:

Prior to testing, sample undergoes specimen validity test. Drug screening is based on Immunochromatography and Bio-Chip Array Technology (Randox) and confirmation is done using Liquid Chromatography-Tandem Mass Spectrometry (LCMS/MS).

Review by Chief Toxicologist:

The final report is reviewed by the chief toxicologist, who provides an expert opinion  on the accuracy of the results on request. The verified report is then shared with the requesting party.

Types of Drug Tests

Several kinds of drug tests vary based on the drugs they detect and the sample they use including;

Urine drug testing (UDT): 

UDT is a common drug test that requires a sample of your urine. It helps detect alcohol, benzodiazepines, amphetamines, cocaine, opiates/opioids, marijuana (THC), etc.

Blood drug testing:

It’s a commonly used sample for drug testing by healthcare providers to detect or provide precise levels of alcohol (ethanol) and drugs.

Hair follicle drug testing: 

A hair follicle drug test can determine patterns of prescription medication misuse and illicit drug use over past one week to an year.

Hair testing can detect phencyclidine (PCP), cocaine, opioids, amphetamines, 3,4-Methylenedioxymethamphetamine (MDMA), etc.
