Quick answer
The Methaqualone Urine Screen is a laboratory test that looks for methaqualone and related compounds in a urine sample. Methaqualone is a sedative-hypnotic substance that has been used as a medication and also appears as a substance of abuse. The screen is used in clinical, workplace, and legal settings where recent use needs to be assessed. Screening results are preliminary and are confirmed with a more specific method when required.
What this test measures
Urine drug screening usually begins with an immunoassay, a fast method that uses antibodies to detect a group of related compounds. The methaqualone screen looks for methaqualone and structurally similar substances. Because screening tests are designed to be broad, a positive result is considered presumptive until it is verified.
When a screen is positive, a confirmatory method such as gas or liquid chromatography with mass spectrometry identifies the exact substance. Specimen validity checks, such as creatinine and specific gravity, help ensure the sample is consistent with normal urine. These steps reduce the chance that a cross-reacting substance is mistaken for methaqualone.
People encounter this test in workplace programs, clinical evaluations, and legal contexts, and it may be part of a larger panel. Collection procedures and cutoff values vary by program. A qualified healthcare provider or medical review officer interprets results with the person's history, medications, and any legitimate explanations.
- Methaqualone in urine by immunoassay
- Related sedative compounds when included in the screen
- Confirmatory identification by mass spectrometry when ordered
- Specimen validity markers such as creatinine and specific gravity
- pH and other integrity checks when included
- Other panel markers when part of a broader drug screen
Why people order this test
- Assess recent methaqualone use in a screening program
- Support a clinical evaluation involving sedative substances
- Provide a presumptive result that can be confirmed when needed
- Document results for workplace or legal requirements
- Help interpret findings from a broader drug panel
How to prepare
No special preparation is usually required, but follow the collecting program's instructions. Tell the collection staff about all prescription, over-the-counter, and herbal products you take, because some can cross-react with screening tests.
Understanding your results
Results are typically available within one to three business days. A preliminary positive screen is confirmed with a more specific method before it is treated as definitive. A qualified healthcare provider or medical review officer interprets results with the person's history and medications.

Is the urine screen result final?
No. Screening results are presumptive. A positive screen is usually confirmed by a more specific technique such as mass spectrometry.
Can other substances cause a positive result?
Cross-reactivity is possible with some compounds. Confirmatory testing distinguishes the exact substance so the result can be interpreted correctly.
How long after use can it be detected?
Detection depends on the amount used, frequency, individual metabolism, and fluid intake. No single window applies to everyone.
Is this a blood test?
No, this order uses a urine sample. Urine is the most common specimen for drug screening.
