Blood Testing

To make an accurate diagnosis, doctors require complementary tests, such as those performed and analysed in a clinical laboratory.

The laboratories are composed of multidisciplinary teams consisting of pharmacists, doctors, biologists, veterinarians and laboratory technicians. The purpose of this team is to analyse human biological samples that will help in the prevention, diagnosis and treatment of some diseases.

    What samples are tested in a clinical laboratory?

    The biological samples that are collected in order to perform the different types of tests are very varied. It can be blood, urine, stools, bone marrow, amniotic fluid or synovium, among others.

    Types of tests performed in a clinical laboratory

    • The blood count is one of the most requested tests. In the area of ​​haematology, the components of the blood and the tissues that form it are studied (bone marrow, lymph nodes …)Biochemistry analyses the chemical elements of the liquid fraction, both blood and urine (glucose, cholesterol, triglycerides, uric acid, creatinine …)In the area of ​​coagulation tests, the tests that are performed will allow to detect bleeding disorders, thrombotic and hypercoagulability states.In microbiology we find a wide variety of tests such as stool analysis, tumour markers, immunology (studies the immune system), endocrinology to evaluate the endocrine system, allergies and toxicology.

    Clinical tests performed at This

    Clinical Biochemistry

    This analysis studies chemical elements of the liquid fraction of blood and urine, such as glucose, cholesterol, triglycerides …

    Clinical haematology

    This area studies the principal components of the blood and the haematopoietic tissues that compose it (lymph nodes, bone marrow, spleen …)


    In these tests, determinations related to the immune system are studied. The most frequent are rubella, HIV, herpes, chicken pox …


    Endocrinology is responsible of the study of disorders produced by the endocrine glands. These tests are performed: T3, free T3, T4, free T4, cortisol …


    The objective of these tests is to diagnose the allergic pathology identifying allergens. For this purpose, advanced immunoassay systems and chemiluminescent technology of high sensitivity and precision are used.


    The purpose is identifying the microorganisms that cause infections present in the body and determine the sensitivity that this infection presents to antibiotics and antifungals to be able to treat it correctly.


    This area studies parasites and their effects on people’s bodies.


    Serology allows to identify the presence of antibodies in the blood. It is often done in blood donations and transfusions.


    Through these tests, the presence of toxic substances in biological samples is studied. In general, the presence of drugs of abuse, drugs, pesticides …

    Molecular biology

    Molecular biology studies the biological processes that happen at the molecular level, between cellular systems such as between nucleic acids and proteins.

    Genetic tests

    These tests allow to identify possible alterations in the DNA sequence related to hereditary diseases or those known as ‘rare diseases’. They are also performed to identify congenital defects or anomalies in the development of the foetus during pregnancy.


    The analysis of paternity is performed to determine or exclude the genetic link between a supposed father and son.

    Nutritional measurement and anti-aging

    Aging is related to life habits and genetics. By performing these tests, you can know the patient’s health status to prevent diseases and pathological processes typical of aging as much as possible.

    Pathological anatomy

    This area allows to diagnose diseases through the analysis of biopsies, cytologies, autopsies or surgical pieces.


    It is a fine needle aspiration biopsy that extracts a quantity of fluid and tissues that can diagnose Hodgkin’s lymphoma.


    It consists of a colouring procedure that allows diagnosing diseases such as cancer, since it determines if there is cancer and at what exactly cellular protein level.

    Molecular and second opinion studies

    Those people who have doubts about the results of their tests performed in other laboratories can get a second opinion in our centres.
