Can a diluted drug test still be positive?

Sometimes dilution is intentional, but it can happen accidentally as well. If the drug levels do not reach a certain cut-off point established by the laboratory, the specimen will not be marked positive for the drug even if it is detected.

Can there be a positive dilute drug test?

Drinking large volumes of just about any non-toxic water-based liquid will dilute urine. Drinking two or three 12-ounce glasses of water at the same time can produce 10-fold diluted urine within only half an hour and the dilution effect may last for hours.

What is a positive dilute drug test result?

A positive dilute drug test result refers to a urine specimen that tested positive for a particular drug metabolite in the urine where the sample contained a higher concentration of water than the average human excretion.

Can you fail a drug test for it being diluted?

Many people think that a drug test result is only one of two things, either positive or negative. However, given the fact that drug tests are not 100 percent accurate, false positives and negatives and such a thing referred to as a dilute negative drug test result can also happen.

What color is dilute urine?

The intensity of the color usually varies with urine concentration; thus, concentrated urine is dark yellow, and dilute urine is pale yellow. Abnormal constituents may alter the color of urine. Bilirubin or its degradation products may give urine a darker yellow color than normal.

What does dilute specimen mean on a drug test?

A dilute specimen is simply a urine sample that has a higher than average water content. It is not, however, an automatic fail. Dilute specimens are defined by the Department of Transportation (DOT) as samples with creatinine and specific gravity values that are lower than expected for human urine.

Is diluted urine normal?

A dilute urine sample means that the creatinine level is equal to or below 20 mg/dL. This also occurs normally in the absence of kidney disease. The creatinine levels can change daily, but most people will have a “normal” value range most of the time.

If the second specimen test result is also returned as dilute, then that is considered a final result and no further tests are performed. The second negative dilute is accepted as a negative test result.

Will 2 liters of water dilute urine?

Typically ingesting 1-2 liters or more within an hour of testing is sufficient to dilute most specimens for a 2–6 hour period. Diuretics such as caffeine and cranberry juice and some medications, including water pills may cause diluted urine samples.

What does a dilute negative drug test mean?

So, in short, a negative dilute result means that the donor was exceptionally hydrated at the time of the test; and the urine, and everything else it contained, was diluted. What's tricky with a negative dilute test result is that it's unknown why the concentration of the specimen was dilute.

How can you tell if urine is adulterated?

Synthetic urine

Like swapped urine, measuring the specimen's temperature is the most common way to detect synthetic urine. Synthetic urine also has a strong unfamiliar odour, which an experienced specimen collector would recognize. Apart from the odour, high-quality synthetic urine will pass every validity test.
