Methaqualone (MQL) Rapid Test

Methaqualone (MQL) Rapid Test by LARKSOIS Pharma is a urine-based rapid screening test designed for the qualitative detection of methaqualone in human urine samples at a 20 ng/mL cut-off level. Methaqualone, also known historically by names such as Quaalude and Mandrax, is a controlled drug of abuse in many countries due to its sedative-hypnotic properties and misuse potential. The MQL rapid test supports laboratories, rehabilitation centers, workplace screening programs, forensic screening settings, and healthcare institutions with a fast, simple, and reliable preliminary testing solution.

Introduction

The Methaqualone (MQL) Rapid Test is a drug of abuse rapid test used to screen urine specimens for the presence of methaqualone.
Methaqualone belongs to the sedative-hypnotic class and was historically marketed under names such as Quaalude, Sopor, and Mandrax. It became widely known before many countries restricted or discontinued its medical use because of abuse potential.
The LARKSOIS Pharma Methaqualone MQL Rapid Test helps identify suspected methaqualone exposure through urine screening. Like most rapid drug tests, it is intended for initial screening, and any non-negative result should be confirmed using an approved laboratory method such as GC-MS or LC-MS/MS.

What Is Methaqualone

Methaqualone is a synthetic sedative-hypnotic compound that was once used medically for sleep-related conditions and sedation. It acts as a central nervous system depressant and was historically compared with barbiturate-like sedatives. Over time, methaqualone became associated with misuse, dependence, and illegal recreational use. Because of these concerns, its legal availability was reduced or banned in many regions.

Why Testing Matters

The Methaqualone urine test is useful because methaqualone is not commonly used as an approved medicine today, yet it may still appear in illegal drug abuse contexts.
A quick MQL urine rapid test can help identify possible exposure and support early decision-making in professional screening environments.
The test does not diagnose addiction, intoxication, or any medical condition by itself. It only provides a preliminary urine screening result for methaqualone at the stated cut-off.

Intended Use

The Methaqualone (MQL) Rapid Test by LARKSOIS Pharma may be used in professional diagnostic and institutional screening environments.

Applications

Drug abuse screening programs
Rehabilitation and de-addiction centers
Workplace drug testing panels
Clinical toxicology screening
Law enforcement and forensic screening support
International diagnostic distribution
Laboratory and institutional drug monitoring workflows

How It Works

The Methaqualone (MQL) Rapid Test is generally based on a rapid immunoassay principle. Immunoassays are widely used in drug testing because they are fast, practical, and suitable for initial screening.
A urine specimen is applied to the test device according to the product insert. The test then produces a visual result within the specified reading time.
For professional accuracy, especially in legal, workplace, or medical decisions, confirmatory testing is recommended for non-negative or disputed results because immunoassay tests may sometimes produce false-positive or false-negative results.

Method

The Methaqualone (MQL) Rapid Test uses a rapid urine screening method for qualitative detection of methaqualone. It is designed to provide a preliminary screening result at the stated 20 ng/mL cut-off.

Benefits

Fast urine screening for methaqualone detection
20 ng/mL cut-off for sensitive screening requirement
Simple visual interpretation for professional users
No complex instrument required for initial testing
Suitable for international drug screening markets
Useful in multi-drug abuse testing programs
Manufactured with quality-focused standards by LARKSOIS Pharma

Specimen

The Methaqualone (MQL) Rapid Test is designed for urine specimens. Urine is widely used in drug screening because it is practical, non-invasive, and suitable for professional toxicology screening workflows.

Guidance

Use urine specimens only
Use fresh urine specimens when possible
Follow the product insert carefully
Treat all urine samples as potentially biohazardous
Read the result within the recommended time
Avoid using damaged or expired test devices
Confirm important results through a certified laboratory

Note

A rapid screening result should be considered preliminary unless confirmed by a validated laboratory method where required.

Cut Off

The Methaqualone (MQL) Rapid Test by LARKSOIS Pharma has a stated cut-off of 20 ng/mL. This means the test is designed to screen urine specimens for methaqualone at or above the validated threshold. LARKSOIS Pharma should mention the exact performance details according to the final product insert, technical file, and regulatory documentation.

Result Interpretation

Positive

A positive or non-negative result suggests that methaqualone may be present in the urine specimen at or above the stated cut-off. Positive results are preliminary and should be confirmed using a recognized laboratory method where required.

Negative

A negative result suggests that methaqualone was not detected or was below the cut-off at the time of testing. A negative result does not always rule out exposure if sample quality, collection timing, or the detection window affects the result.

Invalid

If the valid control indicator does not appear, the test is invalid. The test should be repeated with a new device and fresh urine specimen according to the product insert.
