What are Drug Test Temperature Strips?
Britevent – Britevent is a disposable, self-adhesive urine specimen temperature verification thermometer manufactured by LCR Hallcrest. It is a continuous display liquid crystal thermometer label that adheres to the outside of a urine specimen collection cup and provides an instant, easy-to-read temperature display. Britevent uses proprietary formulations of liquid crystals that change color at designated temperatures, allowing healthcare professionals to quickly verify whether a urine sample falls within the expected temperature range for a freshly provided specimen. Britevent conforms to SAMHSA guidelines and is available in direct read or 2°F offset forms.
Brite Dot – Brite Dot is a high-volume, low-cost disposable specimen temperature verification thermometer manufactured by LCR Hallcrest. It is an adhesive-backed roll label designed for automated, high-throughput application to urine specimen collection cups. Like Britevent, Brite Dot uses liquid crystal technology to display temperature via a color-changing indicator — the green color indicates the correct temperature reading. Brite Dot is specifically engineered for roll-to-roll automated application, making it ideal for large-scale collection facilities and lab environments.
What is Britevent used for?
Britevent is used to verify the temperature of urine specimens at the time of collection to confirm sample integrity and authenticity. It is commonly used for:
- Drug testing and specimen validity verification
- Workplace and employment urine screening
- Clinical and hospital specimen collection
- Doctors’ offices and urgent care facilities
- Compliance with SAMHSA drug testing guidelines
A fresh urine specimen should fall within the normal body temperature range. Britevent provides an immediate visual confirmation of specimen temperature, helping clinicians and collectors detect samples that may be substituted, adulterated, or outside the acceptable temperature window.
How does Britevent work?
Britevent uses a non-toxic mixture of liquid crystal esters sealed beneath a polyester covering film. When applied to the outside of a urine specimen cup, the liquid crystals respond to the temperature of the cup and change color accordingly. The green color indicates the correct temperature reading. If green is not visible, subtract 1°F from the highest lit event to determine the temperature.
How do I read Britevent?
Reading Britevent is simple:
- Apply the label to the outside of the urine specimen cup.
- Wait for the colors to stop changing.
- Read the green color for the temperature — green indicates the correct reading.
- If no green is visible, subtract 1°F from the highest lit event.
What temperature range does Britevent cover?
Britevent covers a standard range of 88°F to 102°F (32°C to 39°C), encompassing the expected temperature window for a freshly provided urine specimen. It is available in the following configurations:
- Product 4030: °F range, 88–102°F
- Product 4030B: °C range, 32–39°C
- Product 4100: °F range, 90–100°F
- Product 4486: °C range, 32–37°C
How accurate is Britevent?
Britevent is accurate to ±1°F / ±0.6°C.
What packaging options are available for Britevent?
Britevent is available in two packaging formats:
- Sheets of 62 Kiss Cut labels (die cut to the top layer but not the backing)
- Individual Split Back bags of 100 (easy to remove backing for quick application)
Is Britevent compliant with drug testing regulations?
Yes. Britevent conforms to SAMHSA (Substance Abuse and Mental Health Services Administration) guidelines for urine specimen temperature verification in workplace drug testing programs.
What is the shelf life of Britevent?
Britevent has a shelf life of 12 months from the invoice date when stored at room temperature (21°C / 70°F and 50% relative humidity).
How should Britevent be stored?
Store Britevent at room temperature (21°C / 70°F) with approximately 50% relative humidity. Keep away from excessive heat, direct sunlight, and moisture to maintain performance and shelf life.
What is Brite Dot used for?
Brite Dot is used to verify the temperature of urine specimens at the point of collection, ensuring sample authenticity and integrity. It is commonly used for:
- High-volume drug testing laboratories and collection sites
- Automated specimen processing workflows
- Workplace and employment urine drug screening programs
- Clinics, hospitals, and collection facilities requiring roll-stock label formats
Brite Dot fills the need for a fast, accurate, and cost-effective temperature verification solution in facilities that process large numbers of specimens and require automated label application.
How does Brite Dot work?
Brite Dot works the same way as Britevent — apply the label to the outside of the urine specimen cup and read the green color for the temperature. The liquid crystal indicator responds instantly to the cup surface temperature and displays the reading through color change.
How do I read Brite Dot?
Reading Brite Dot is straightforward:
- Apply the label to the specimen cup.
- Read the green color for the temperature.
What temperature range does Brite Dot cover?
Brite Dot covers 90–100°F and 32–38°C with a 2°F offset (Product Code D4630 ADR3000).
How accurate is Brite Dot?
Brite Dot is accurate to ±1°F / ±0.5°C
What size is Brite Dot?
Brite Dot labels measure 1.5″ x 0.3937″ and are supplied on a clear polyester release liner in rolls of 3,000 labels.
What packaging does Brite Dot come in?
Brite Dot is packaged as rolls of 3,000 adhesive-backed labels on a clear polyester release liner, making it compatible with automated roll-to-roll label application equipment.
Is Brite Dot appropriate for automated applications?
Yes. Brite Dot is specifically designed for roll-to-roll automated application, making it the ideal choice for high-volume collection facilities that apply labels using automated dispensing equipment.
