Established over 30 years ago

MEDICHEM has over 30 years of experience as a developer, manufacturer and distributor of in-vitro diagnostics.

The company was founded in 1986 as a sole proprietorship by Atou Khalide Lô. In 1998, his son Insa Lô became a partner in the company after eight years of collaboration, and took the role of managing director in 2004.


Initially, the development and manufacture of clinical-chemistry reagents was the predominant focus of the company. Today, our product range includes reagents for the determination of a diverse array of parameters, e.g.,
α-amylase, alkaline phosphatase, blood alcohol, total bilirubin 

DPD, cholesterol, CHOD/PAP, CHE, creatinine PAP, CK, iron, total protein, glucose, GOT (ASAT), GPT (ALAT), GGT, uric acid PAP, urea, copperPAESA, lipase PAP, microproteins, acid phosphatase, triglycerides GOD/PAP, D-xylose and others.

Reference materials

In 1989, MEDICHEM began working closely with forensic institutes and medical laboratories to develop reference materials for quality control of toxicological and forensic analyses.

Soon after, MEDICHEM was commissioned with the manufacture of control samples for ring tests. These samples were used both domestically and internationally as external quality controls by reference institutions, beginning with the DGKL (German Society for Clinical Laboratory Medicine, formerly DGKC), the CSCQ (Centre Suisse de Contrôle de Qualité) and the SFTA (Société Française de Toxicologie Analytique), among others.

In 1995, MEDICHEM introduced the protected trademarks Medidrug® and Medisafe® to designate its reference materials. In clinical-chemical laboratories, as well as in toxicology and forensic medicine institutes, the Medidrug® and Medisafe® brands have become the standard for independent reference materials, the use of which guarantees quality control of analytical methods that is independent of reagents or instruments from specific manufacturers.

Our quality controls are manufactured in close cooperation with our clients in toxicological and forensic medical institutes in Germany and abroad, as well as in accordance with the guidelines of professional associations such as the GTFCh (Society for Toxicological and Forensic Chemistry), the SFTA (Société Française de Toxicologie Analytique), the SoHT (Society of Hair Testing), the EWDTS (European Workplace Drug Testing Society) or the German Medical Association.

Hair reference materials

The number of analytical methods and tested substances is constantly increasing. However, quality control materials with verified target values and reliable sample homogeneity are usually not available on the market in practical concentration ranges for most applications.

Therefore, MEDICHEM has begun to develop new manufacturing methods for hair reference materials. The main focus lies on preserving hair structure by avoiding grinding processes.

Our segmented hair reference materials with extremely uniform segment lengths of 1mm have been available since 2012, at first as authentic and spiked controls for alcohol consumption markers, later on as spiked hair controls for narcotics and drugs.

Hair controls are available in various significant concentration ranges in accordance with the recommended cut-offs of professional associations such as the GTFCh (Society of Toxicological and Forensic Chemistry), the SoHT (Society of Hair Testing), the EWDTS (European Workplace Drug Testing Society) or other associations.


Our company is certified according to
DIN EN ISO 9001 : 2015 and DIN EN ISO 13485 : 2016.

We will gladly send you the certificates upon request.
