Urine drug test

The use of a urine drug test is one of the methods used to detect the presence of various drugs. Urine tests for drug screening are used, among other things, to ensure that the employees concerned are not under the influence of substances during their professional activities. In this context, these tests are used, among other things, following a drug rehabilitation. The employer therefore seeks to ensure compliance with the zero-tolerance policy regarding the consumption of substances in the workplace. These tests are also used for pre-employment screening in certain employment sectors. They are also useful for personal home use. Collecting and reading sample results requires that you follow the appropriate steps to accurately determine test results. This involves becoming familiar with the components of your urine drug test and knowing how to interpret the results of it.

So, remember to follow the tips mentioned below to properly read and understand your urine drug test result.

1. Locate the control areas and test areas for each of the substances that may be detected on your urine test for drug screening

Each urine drug screening container label contains two regions – the control region (C) and the test region (T). The control region indicates that the test is working properly, while the test region indicates the presence or absence of the drug, medication, or other substance you are looking for.

After collecting the urine sample in the cup used to transfer the sample into the test container or after collecting the urine directly into the test container, wait until the line appears opposite the line of the control region (C). However, if the control line does not appear after 5 minutes following sample collection, it is recommended that the test container be discarded and a new one administered.

2. Collect an adequate sample volume to perform your drug test well

The person being tested for drugs can be for various reasons such as probation, new hire, pre-employment test, test following reasonable suspicion, follow-up, return to work following rehab, to name a few reasons.

The person must then provide a urine sample of a minimum volume defined according to the type of test used, often indicated by a line. Keep in mind that a significantly lower sample volume may not give accurate results. Also, maybe the donor is resisting the test by not providing enough sample or they have a bladder that is not working very well and therefore cannot provide as much as they would like.

3. Wait 5 minutes before interpreting your drug test (depending on the type of test you are using)

Obtaining almost instantaneous results after a sample is collected is one of the significant advantages of urine drug testing.

Tip: It is recommended that you do not read urine drug test results more than ten minutes after sample collection. Although most results are stable for approximately 1 hour, after this time they may lose accuracy before sample collection.

4. Identify the colored lines on your drug test

  • Negative test results at a urine drug test

Depending on the type of test you are using, if you notice that a colored line appears in both the control and test regions (different substances targeted for detection), the result is negative for the substance in question. A negative drug test result indicates that the drug or drugs in question were not found in the sample. However, when evaluating the results, do not consider the intensity of the color of the line. Indeed, a pale and even very pale line may be present and thus confirm the presence of a given substance. It is therefore not necessary to obtain a dark pink line, for example, to assert positivity. Using a magnifying glass can sometimes be useful to properly interpret a result.

  • Presumed positive test results and invalid test at a urine drug test

Depending on the urine test used, a colored line present in the control region and no line in the test region indicates a presumptive positive drug test result. Such a result indicates the detection of one or more drugs. However, we cannot confirm the positivity of a qualitative test (sold to companies or individuals) before having it validated in the laboratory by a quantitative test. A quantitative test carried out in the laboratory uses techniques which make it possible to know the quantity of one or more drugs according to the sample analyzed. In addition, before assuming positivity in a qualitative test, it is important to ensure the presence of a control line at the locations indicated on the test. Otherwise, the test performed is invalid and another one will have to be performed.
