For more than 70 years, Ketterthill Laboratories have been the preferred healthcare partner for medical tests in the Grand Duchy of Luxembourg. Our medical expertise combined with a cutting-edge technological platform ensures we can offer patients a comprehensive service, ranging from routine blood tests to even the most highly specialised tests.

A close relationship

Beyond our medical test activity, we attach great importance to human contact, making patients and their doctors the core of our focus. Through a national network of over 70 blood collection centres and locations, we offer citizens a convenient local service and provide prescribing doctors with an array of services to support them in their diagnosis and treatment of patients.

Our team of clinical biologists ensures that patients and prescribing doctors can benefit from a direct contact person, permanent support and confidential results.

Offering the best possible care, together

Ketterthill has been a member of the Cerba HealthCare network since 2011. Cerba HealthCare is an international medical biology network with a set of common values, built on the synergy and the complementary nature of activities and men and women. It operates in the medical test market, primarily focusing on the private and public sectors and clinical trials.

Cerba HealthCare is an interdependent and interconnected group that presents doctors, medical laboratories and pharmaceutical industries with a comprehensive offering in terms of biological diagnosis, ranging from local to highly specialised biology laboratories.

Medical expertise

  • Created in 2005, the Laboratoire Luxembourgeois d'Immuno-Pathologie (LLIP) is focused on testing for and identifying antibodies as part of the diagnosis and monitoring of autoimmune diseases, such as:
    • inflammatory diseases
    • organ-specific diseases (e.g. hepatitis)
    • neurological diseases
  • Haematology involves the study of blood and, more specifically, the blood cells which ensure tissue oxygenation (red blood cells), help maintain our immune defences (white blood cells) and regulate clotting (platelets).

    We handle tests in the following areas:

    • Cytology (quantitative and qualitative study of blood cells; measurement and calculation of erythrocyte constants, etc.)
    • Haemostasis (determination of clotting time; identification of the risk of bleeding or thrombosis)
    • Immunohaematology (blood typing, irregular antibody screening, detection of cold agglutinin disease)
  • Clinical biochemistry enables the measurement of non-cellular components involved in the chemical reactions which take place in living organisms. Such 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)
    Specialised biochemistry involves testing for and assaying more specific elements to assist with the diagnosis of particular diseases or the monitoring of various clinical situations. 

    It reflects more specific examinations, such as:
    • specific proteins
    • tumour markers
    • hormone assays
  • Serology of infectious diseases involves the detection and/or quantification of antibodies produced by certain white blood cells resulting from an infectious disease (viral, bacterial or parasitic) or as a side effect of vaccination.

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

  • Microbiology is a discipline which aims to isolate and identify bacteria, parasites, viruses and fungi. It also involves the study of antibiotic sensitivity via antibiograms.

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

  • Molecular biology is an analysis technique which detects the presence of bacterial or viral nucleic acid (DNA or RNA) in a biological sample, or genetic mutations within human cells.

    At Ketterthill Laboratory, we use this technique to test for sexually transmitted infections such as Chlamydia trachomatis, gonococcus and Mycoplasma genitalium.
  • The purpose of spermatology is to test a man with a view to assessing his fertilising ability when a couple is experiencing fertility problems.

    Our Fertility Department currently offers the following:
    • Semen analysis (quantitative and qualitative examinations of sperm to assess fertilising ability)
    • Sperm enrichment (selection of as many sperm as possible for in utero injection)

    We also perform post-vasectomy checks.
