The Ketterthill Laboratory

For over 70 years, Ketterthill Laboratory has been the privileged partner for medical biology analyses in the Grand Duchy of Luxembourg. Our medical expertise, combined with a high-tech platform, enables us to offer complete patient care, from routine sampling to the most specialized analyses.

Close to you

Beyond our analytical activities in medical biology, we attach great importance to human contact, and put patients and their doctors at the heart of our concerns. Through a nationwide network of over 100 laboratories, we offer local service to the public, and provide prescribing doctors with a range of services to support them in their diagnosis and treatment of patients.

Our team of medical biologists Our team of medical biologists guarantees patients and prescribing doctors privileged contact, constant attention and confidential results.

Strong corporate values

Professional expertise

We are dedicated to maintain and reinforce our team’s knowledge by encouraging ongoing training.


We owe to our patients and doctors the highest quality of service, which translates into an irreproachable welcome, the reliability of our results and their delivery in the shortest possible time.


We are committed to conducting our business with respect for the patient, medical ethics and best professional practices as our primary concern.

Strong presence

Patients and prescribing doctors are at the center of Ketterthill’s vision. Our team is present at every stage of the analysis process, from sampling to the communication of results, to provide information and advice.

Cerba HealthCare, enlightening health

Ketterthill has been a member of the international Cerba Healthcare network since 2011. Cerba HealthCare, a key player in medical diagnostics, aims to support the evolution of healthcare systems towards more preventive care. It benefits from more than 50 years of expertise in medical biology to better assess the risk of disease development, detect and diagnose pathologies at an earlier stage, and optimize the effectiveness of treatments by personalizing them.

Every day, across 5 continents, the Group’s 15,000 employees are helping to transform medicine, driven by the same deep-seated conviction: advancing diagnostics means advancing healthcare.

Our medical areas of expertise


Created in 2005, the LLIP (Luxembourg Immuno-Pathology Laboratory) is focused on the research and identification of autoantibodies as part of the diagnosis and monitoring of autoimmune diseases such as :

    • Inflammatory diseases
    • Organ-specific diseases (hepatitis, etc.)
    • Neurological diseases

Hematology involves the study of blood, and more specifically of the blood cells that ensure oxygenation of tissues (red blood cells), contribute to immune defenses (white blood cells) and ensure the proper functioning of coagulation (platelets).

We carry out tests in the following areas:

    • Cytology (quantitative and qualitative study of blood cells, measurement and calculation of erythrocyte constants, etc.).
    • Hemostasis (determination of coagulation times, identification of hemorrhagic or thrombotic risks)
    • Immunohematology (determination of blood group, screening for irregular antibodies, detection of cold agglutinins)
General and specialised biochemistry

Clinical biochemistry measures the non-cellular components involved in the chemical reactions taking place in living beings. These components, represented by carbohydrates, lipids and proteins, are quantified in biological fluids such as blood or urine. This activity reflects the most common prescriptions received by the laboratory, such as:

    • Blood sugar level (blood glucose)
    • Lipid profile (cholesterol, HDL, LDL, triglycerides)
    • Inflammatory markers (CRP)

Specialized biochemistry is used to identify and measure more specific elements to help diagnose particular diseases or monitor different clinical situations. It corresponds to more specific tests, such as :

    • Specific proteins
    • Tumor markers
    • Hormone assays
Infectious diseases serology

Infectious diseases serology involves the detection and/or quantification of antibodies produced by certain white blood cells resulting from an infectious disease (viral, bacterial or parasitic) or a side effect to vaccination.

It is used to screen for hepatitis, toxoplasmosis, Lyme disease, herpes virus infections and sexually transmitted infections, among others.


Microbiology is a discipline which aims to isolate and identify bacteria, parasites, viruses and fungi. It also enables the sensitivity of bacteria to certain antibiotics to be studied (production of an antibiogram).

The laboratory handles analyses in the fields of bacteriology, parasitology, virology and mycology.


Molecular biology

Molecular biology is an analytical technique used to detect the presence of bacterial or viral nucleic acid (DNA or RNA) in a biological sample, or genetic mutations within human cells.

At Ketthertill Laboratory, we use this technique to detect sexually transmitted infections such as Chlamydia trachomatis, gonococcus and mycoplasma genitalium.


The aim of spermiology is to carry out tests on men to assess their fertilizing capacity when a couple is experiencing fertility problems.

Our fertility department currently performs :

    • Sperm analysis (quantitative and qualitative examination of sperm to assess its fertilizing capacity)
    • Sperm enrichment (selection of a maximum number of spermatozoa for in utero injection)

We also carry out post-vasectomy checks.

LLIP : a specialized department of our laboratory

Luxembourg Immuno-Pathology Laboratory

Created in 2005, the LLIP (Luxembourg Immuno-Pathology Laboratory) is focused on the research and identification of autoantibodies as part of the diagnosis and monitoring of autoimmune diseases such as :

    • Inflammatory diseases
    • Organ-specific diseases (hepatitis, etc.)
    • Neurological diseases
A world-renowned center of expertise

The laboratory receives almost 120 samples a day from Luxembourg and European countries such as Belgium, France, Germany, Switzerland, Portugal, Italy and Greece.

A biologist and three specially trained technicians are part of this team, whose skills are constantly evolving in the mastery of different analysis and interpretation techniques.

The LLIP holds a serum library of over 5,000 serum samples from various autoimmune diseases, which serve as a reference for the verification of techniques.

“More than a hundred different autoantibodies are tested at the LLIP.”
