Rapid Blue is the go-to liquid leak locating dye for professionals and homeowners alike. Our unique formula quickly identifies the source of any water leaks, saving you time and money.

We’re committed to providing the highest quality products possible and making all of our products in the United States.


Rapid Blue Dissolve Bluing Tablets are placed directly in the toilet at your collection site to ensure sample integrity. Bluing tabs will dye the water blue, which will negate any donor from using clear toilet water to dilute their urine samples.

Blue dye is a coloring agent that is used to detect whether a urine specimen donor has tampered with the specimen provided.

One tablet of Rapid Blue in a toilet bowl or toilet tank will turn the water blue. If a donor attempts to dilute their own specimen or substitute the entire specimen with the water from either of these sources, the collector will be able to easily detect it.

Our Story

The story of Rapid Blue® continues to evolve. 

In late 2018, developed a promotional idea for conferences, which later transformed into a flagship product, Rapid Blue®, and a new family business. During one such conference, co-founder James White was approached by an attendee who expressed interest in purchasing a large quantity of dissolving blue dye tablet bottles. Over lunch, they negotiated a price, and a new US manufacturing business was born.

On March 10, 2023, Ferguson Financial Holdings LLC acquired the Rapid Blue® brand. Their involvement is expected to provide a fresh perspective and innovative strategies to help the brand expand and succeed further.

With the guidance of Ferguson Financial Holdings, the brand anticipates experiencing an even greater expansion in its reach and product line, fostering more growth and success.
