Drug test cups are popular for a reason. Urine drug testing is used for pre-employment screening, compliance assessment, and home substance abuse prevention. So you've opted for a 5-panel, 10-panel, or 12-panel drug test; now what?
Once you've selected the appropriate urine collection cup, you can move forward with testing and interpretation of results.
Each panel will have its own Control Region (C) marked at the top, and a Test Region (T) specific to the drug being tested.
If the Control line does not appear after 10 minutes of obtaining a sample, discard the test and administer a new one.
Most people will opt for a multi-drug test kit like the 12 Panel DrugConfirm Advanced Flat Panel Urine Drug Test Cup with Adulterants to save time by detecting several substances at once.
Instant urine drug tests (i.e. cups and dip cards), as well as mouth swab drug tests, are designed to yield results just a few minutes after a specimen collection. Tip: Do not read drug test results more than 10 minutes after a sample is collected.
If a colored line appears next to both the Control Region and Test Region (as shown above), the result is NEGATIVE. The color intensity (faintness or darkness) of the line is not a factor when assessing results. A faint line DOES NOT mean the specimen contains small amounts of a specific drug metabolite.
When no line appears in the Test Region (T) but a colored line is displayed in the Control Region (C), the drug test result is POSITIVE.
A positive urine test result might be the start of action against an employee, parolee, student, etc. who abuses illicit substances.
Before a positive result can be ascertained, the Control Region (C) should be marked with a colored line to indicate the test is valid and non-defective.
NOTE: Instant immunoassays are only used for preliminary screening. Positive test results obtained through instant drug tests should be sent to a SAMHSA-Certified laboratory site for confirmation.
A urine test cup usually contains a temperature strip, which is built in to detect abnormalities in the specimen. Temperature strips for urine testing can also be applied separately by a Third Party Collector (TPA).
An acceptable urine temperature for drug test analysis falls between the range of 32–38 °C (90–100 °F). If the drug test temperature is out of range, it is possible the urine is adulterated by substances (i.e. water) indicating the drug test has been falsified. Again, a TPA will have the greatest understanding of drug test results.
Tight control on the collection process guards against adulteration. Other ways to prevent cheating:
You may have noticed that the medical staff may be measuring the temperature of the urine samples submitted to them. Looking through a sample specimen is not enough to verify that the sample submitted is authentic. Therefore, the medical staff makes use of an adulterant test to determine if the samples have been tampered with.
However, no one can be certain if the sample was merely a “good-quality” fake urine or was obtained from another person. Measuring the temperature is an effective way to verify that the sample came from the person being tested.
When obtained fresh, human urine is typically at 94-96°F. However, the temperature may change as soon as it is exposed to either warm or cool environment. For drug testing, a urine temperature that is within the range of 90-100°F is usually acceptable.
Temperatures that go lower or higher than this range is likely tampered or contaminated. If this is the case, the sample will be rejected.
A standard thermometer strip has color-based indicators to determine the temperature of the urine sample. Although this kind of product may come in different models and forms, most of them follow this standard set of instructions:
The best way to ensure that you’re using the product correctly is to read the instructions manual that comes together with the kit.
As a precautionary measure, keep the cup away from direct exposure to sunlight or temperatures beyond 55 degrees Celsius.
The normal temperature of human urine ranges from 94°F to 96°F (about 35°C). The temperature of a drug test sample should be read during the first 4 minutes after it was received, as the sample temperature may change depending on the ambient environment.
Acceptable temperature range is from 90°F to 100°F (32°C - 38°C). Any sample with a temperature outside this range should be deemed suspicious.
What’s amazing about the urine drug test cup with thermometer strip is that it can read the sample’s temperature (in Fahrenheit or Celsius). A newly collected urine sample should be warm to the touch, and so the thermometer strip allows you to check whether the sample is obtained fresh or adulterated.
Here is a step-by-step procedure on how to collect the sample in a urine drug testing cup with thermometer strip:
Drug tests to determine the presence of illicit drugs involve the use of bodily fluids for testing. Urine drug testing is the most commonly used type of drug test. The benefits of using urine drug test include the following:
Drug test cups are often applied within:
Urine drug tests are convenient and affordable. Key features include:
Urine drug tests can detect many illicit substances, not limited to:
There are two basic types of urine drug testing:
Urine Screening Test
This type of test uses immunoassay to find the parent drug and/or metabolite. Most common drugs screened include cocaine, amphetamines, opiates, marijuana, PCP, methadone, and benzodiazepines.
Urine Confirmatory Test
This type of urine drug test undergoes gas chromatography/mass spectrometry (GC/MS) or high-performance liquid chromatography (HPLC) testing in a laboratory setting. This type of test is highly specific and is used in testing for the presence of a specific drug, especially when the initial screening test produces a positive result.
A large percentage of individuals may not be aware of the right kind of receptacle to use in collecting urine that is intended for drug testing or for a pregnancy test. For instance, no matter how clean a container may appear to be, the presence of bacteria may affect the results of the urine test.
An ideal urine collection cup should have the following specifications:
Urine drug tests may come in different forms, such as urine drug cassettes and urine drug test dip cards. However, to ensure that you can collect the desirable amount of urine sample, the Sterile Urine Collection Cup with Temperature Strip may just be the best diagnostic aid that you need.
This urine collection cup is designed to provide a convenient way of collecting urine samples. This includes a secure screw that prevents specimen leakage and possible contamination. Apart from having a wide-mouthed sterile cup, each sterile cup has a temperature strip to protect from urine contamination. The sterile cup has a maximum capacity of 90 mL, the amount enough to be used for testing.
A 30 mL midstream urine sample is needed to conduct a standard urine drug test like the 10 Panel T-Cup CLIA Waived Urine Drug Test Cup. The specimen is collected in the privacy of a restroom.
The collector then pours the sample into a specimen container, which is sealed to prevent the sample from being tampered.
Test results appear on the indicated panels within 5 or 10 minutes. Preliminary positive tests should be sent to an accredited laboratory for further analysis. A GC/MS confirmatory test will be executed to be certain of the kind of drug present in the sample.

Urine drug testing is very effective in detecting recent use, typically in the past 1-3 days. It is suitable for all testing reasons and can be used for a wide range of illegal substances and prescription drugs.
However, it is important that for individuals scheduled to undergo a urine drug test to disclose their full medical history, including medications are taken (such as herbal supplements and over-the-counter medications) since some of these substances may contain similar drugs.
It is highly likely that an individual taking prescribed opiates may show a positive urine drug test result. However, this can be sorted out by using a confirmatory test. Similarly, some diet pills contain amphetamines and methamphetamines, which may also a positive result.
One of the major challenges in urine drug testing is the illegal practice of manipulating the specimens to produce a false negative result. Drug users consider masking their urine samples to avoid being caught.
Some of the common substances that people use to tamper with urine specimen include hypochlorite bleach, table salt, toilet bowl cleaner, laundry detergent, glutaraldehyde, potassium nitrate, and pyridinium chlorochromate. Adding these chemicals may invalidate a drug test result. Therefore, being able to determine the temperature of the urine sample can deter possible hacking of urine samples.
On top of this, drug testing laboratories can already detect the presence of adulterants and contaminants in the urine sample.
It is for these reasons that temperature strips have become very helpful in determining if the urine sample is contaminated or tampered.
To ensure that drug test results are always accurate, make sure to only use sterile urine collection cups to avoid having false negative or false positive results.
