LDN was founded in 1996 with the goal of developing and supplying specialty  in-vitro diagnostics test systems and innovative technologies to the clinical and research laboratory markets.

From the beginning, the determination of Biogenic Amines with immunological test systems was the focus of the business – the efforts of the company resulting in their current position as world market leader in this field. Integral to this success were the assays for the quantitative determination of Free Metanephrines in plasma, the Catecholamines, and  Serotonin.

This positive outcome encouraged the company to expand the business to related diagnostic areas such as Food Control (HistaSure™, Histamine Food ELISA, HisQuick™), Food Intolerance (Histamine in Stool), Neurotransmitters and Amino Acids .

Next, LDN introduced a comprehensive panel of ELISA and CLIA assays in the field of Infectious Diseases with specialities such as EBV, ToRCH and Helicobacter.

LDN's Endocrinological panel offers quantitative enzyme immunoassays for routine and specialty parameters e.g. Free Testosterone, 17-OH-Progesterone, Chromogranin A, DHT, Estrone.
