Whether you are an employer carrying out workplace drug screening, a parent concerned about your child, or simply trying to understand a drug test result, a urine drug test kit (Ujian Saringan Air Kencing) can sometimes be confusing.
Most rapid drug test kits in Malaysia use short 3-letter codes to show which drugs they test for. But what do these codes actually mean?
Here is a simple guide to help you understand the most common drug codes found on urine test kits in Malaysia.
What Do the Drug Codes Mean?
Drug test kits are commonly used by clinics, the National Anti-Drug Agency (AADK), workplaces, and other organisations.
The codes are usually based on the scientific names of the drugs. Some of the common ones include:
- MET – Methamphetamine, commonly known as Syabu
- AMP – Amphetamine, commonly known as Pil Kuda
- THC – Cannabis, commonly known as Ganja
- MOP – Morphine/Opiates, which may include Heroin
- BZO – Benzodiazepines, such as Erimin-5
- KRA – Kratom, commonly known as Ketum
| Test Code | Scientific Name | Common Street Names in Malaysia |
|---|---|---|
| MET | Methamphetamine | Syabu, Crystal, Ice, Glass, Batu, Speed |
| THC | Tetrahydrocannabinol | Ganja, Kanabis, Marijuana, Weed |
| MOP / OPI | Opiates / Morphine | Heroin, Kodein (Codeine), Morfin, Candu, Tramadol |
| AMP | Amphetamine | ATS (Amphetamine-Type Stimulants), Speed, Pil Kuda |
| KET | Ketamine | Ketamin, Special-K, Cat-Valium, K |
| BZO | Benzodiazepines | Erimin-5, Nimetazepam, Happy 5, Sleeping Pills |
| KRA / MTG | Mitragyna / Kratom | Mitragyna, Kratom, Ketum, Air Ketum |
| MDMA | Methylenedioxymethamphetamine | Ecstasy, Ekstasi, E, XTC, Beans, Love Drug |
| COC | Cocaine | Cocaine, Coke, Crack, Flake, Rocks, Snow |
In Malaysia: MET (Syabu), THC (Ganja), and AMP (Pil Kuda) are among the commonly tested substances. KRA (Ketum) is also increasingly included in some drug screening kits.
How Long Can Drugs Be Detected in Urine?
One of the most common questions about ujian saringan air kencing is how long a drug can be detected.
There is no exact time that applies to everyone. It can vary depending on the person’s body, how often the drug is used, the amount taken, and other factors.
As a general guide:
- MET & AMP (Syabu / Pil Kuda): About 2–5 days
- THC (Ganja): About 3–10 days for occasional use; longer with frequent or heavy use
- MOP (Heroin / Morphine): About 2–4 days
- BZO (Erimin-5): Up to about 7 days for occasional use; potentially much longer with regular use
- KRA (Ketum): Generally about 3–7 days
These are only general estimates. A negative test does not necessarily mean a person has never used a drug.
How to Read a Drug Test Kit
Most rapid urine drug test kits have two markings for each drug:
- C = Control
- T = Test
Drug tests work differently from pregnancy tests. For most test kits:
- Negative Result
Two lines appear: one at C and one at T. Even a faint T line is generally considered negative. - Positive Result
Only the C line appears. There is no T line for that particular drug. - Invalid Result
The C line does not appear. This means the test did not work properly and should be repeated with a new test kit.
Important Reminder
Rapid urine drug tests are screening tests, not final confirmation tests. A positive result should be confirmed by a laboratory test, such as GC-MS, especially when the result is being used for medical, employment, or legal purposes.
