About Biochemical Diagnostics, Inc.


On April 22, 2016 Kova International Inc. acquired Biochemical Diagnostics Inc. Founded in 1981 and based in Edgewood NY, Biochemical Diagnostics is a leading manufacturer and marketer of controls and disposable sample preparation products which are used in drugs of abuse testing. Biochemical Diagnostics' products are utilized in toxicology and clinical laboratories as well as in handheld devices for point of care testing. With the acquisition of Biochemical Diagnostics, Kova’s product line expands into the drugs of abuse testing area.  This provides the combined company with opportunities to cross-sell Biochemical Diagnostics’ products through Kova’s robust distribution network.


The acquisition of Biochemical Diagnostics by Kova was a win-win. This was a natural fit for both companies, bringing together industry leaders with a history of integrity, quality and leadership. For Kova, there was a broadening of the their already industry leading product line. For Biochemical Diagnostics, a leader in toxicology controls, it was an opportunity to get their products to Kova’s well-established international distribution network.

Innovative Products


Biochemical Diagnostics introduced gravity flow, polymeric SPE devices years before the competition realized its importance. The Multi-Prep® TLC spotter is an innovation that revolutionized the drug screening market allowing laboratories to process thousands of samples daily with a greatly reduced staff. The Steroid-Skreen™ and VMA-Skreen™ kits are still relevant. Today, the Multiprep® Sample Preparation/Evaporation hardware (SP/E), combined with gravity flow columns, is similarly enabling the preparation of thousands of samples daily for analysis by GC/MS and LC/MS. The ready-to-use Multi-Prep®, Detectabuse® and Stat-Skreen® liquid urine drug controls along with Salivabuse® oral fluid controls are considered the most stable available.

As a pioneer in the field, Biochemical Diagnostics leads with an ongoing, innovative, evolution of off-the-shelf and custom tailored products in the fields of sample preparation and drug control material. Biochemical Diagnostics proudly offers FDA/DEA approved products and ISO certified manufacturing practices.
