Does Synthetic Urine Work at Quest Diagnostics?

If you're searching for whether synthetic urine works at Quest Diagnostics, you're not alone. Many people wonder: Can Quest Diagnostics detect Quick Fix? In fact, in early 2025, Quest issued a stark warning that drug-test cheating had hit a 30-year high. At the same time, the lab was under fire after a faulty reagent led to false positives in California prisons, and one technician was later accused of falsifying test results. Whether you’re preparing for a test or just curious, this guide explains what Quest looks for, how fake pee products perform, and what risks you should understand in 2025.

How Does Quest Diagnostics Detect Synthetic Urine?

Quest Diagnostics uses a process called Specimen Validity Testing (SVT) before any drug screening. This process determines if the sample is genuine human urine. Some of the checks include:

• Temperature (must be between 90–100°F)
• Creatinine concentration
• Specific gravity (dilution)
• pH balance
• Presence of uric acid and urea
• Oxidants or adulterants

Any inconsistency could lead to a sample being marked as invalid or substituted, which may require retesting or result in a fail depending on the reason for the test.

Can Quest Diagnostics Detect Quick Fix?

Quick Fix is one of the most widely used fake pee brands, but like all synthetic urine products, it carries a risk. In many cases, Quick Fix passes basic tests — but not always. Labs like Quest continue to evolve, and using a poorly heated or outdated version increases your chances of being flagged.

What Happens If Quest Flags a Sample as Fake?

If Quest Diagnostics detects synthetic urine or finds your sample to be invalid, here’s what may happen:

• You may be asked to provide another sample under direct supervision
• The result may be reported as "Substituted" or "Invalid Specimen"
• Your employer or agency may treat it as a failed test

This is why some people choose same-day cleansing drinks instead of synthetic urine. See our selection of detox drinks for an alternative approach.

Tips for Minimizing Risk

• Use up-to-date products only
• Pre-test your kit at home
• Ensure correct temperature with heating pads or digital warmers
• Review product instructions thoroughly
