"We process daily internal quality controls and monthly external quality controls to ensure the highest accuracy in the analysis results".


The Biochemistry Service of the Clínica Universidad de Navarra is responsible for performing and interpreting the analysis of biochemical quantities requested to our laboratory. It manages the pre-analytical, analytical and post-analytical phases of biochemical determinations. 

For this purpose, it has state-of-the-art analytical equipment and participates in numerous external quality assurance programs. It has implemented a Quality Management System according to ISO 15189, being accredited by ENAC (technical annex rev.5 / date 10/09/2021) for spectrophotometry, indirect potentiometry, immunoturbidimetry and immunoassay tests.

As part of the commitment to patient care, a response time has been established for a general analysis that allows specialists to have a second consultation with the patient on the same day to inform him/her of the results obtained and make decisions accordingly.

The Biochemistry laboratory of the Clínica Universidad de Navarra is also one of the 3 expert centers in porphyria in Spain according to the European Porphyria Network (EPNET).

We actively participate in our own research projects or in collaboration with other Services and specialists from other centers. It also performs analyses for research teams from the Institute of Health Research of Navarra and external centers or companies through the Research Support Laboratory (LAI).

The specialists of the Service have a strong teaching character as they teach undergraduate and postgraduate subjects in the Faculties of Medicine, Pharmacy and Science, and are accredited by the National Agency for Quality Assessment and Accreditation (ANECA).

Research support

Service platform that provides methodological and technical assistance to research projects, both internal and from other research centers, universities or external companies.

Organized in assistance areas

Our goal is to make a quick diagnosis in order to establish the most appropriate treatment as soon as possible

General Biochemistry and Urine

The most frequently requested blood and urine parameters are analyzed.

These tests are highly sensitive in detecting damage and its severity, so their results are essential for guiding the diagnosis and monitoring the evolution of patients.

Spectrophotometric, potentiometric and immunoturbidimetric methods are used.

Hormones and tumor markers

They include endocrinological and metabolic analyses under basal conditions and some parameters that are analyzed under controlled stimulation conditions, using electrochemiluminescence immunoassays and radioimmunoassays (RIA).

Molecules that allow the diagnosis and evolutionary follow-up of different diseases, mainly oncological, are also quantified by means of electrochemiluminescence immunoassays and ELISAS.


Blood and urine magnitudes of interest in the diagnosis and monitoring of nutritional status, inflammatory processes, hematological, renal and immunological diseases are analyzed. As well as cerebrospinal fluid analysis for the diagnosis of some neurological diseases.

The analyses are performed by spectrophotometry, gel electrophoresis, immunonephelometry, immunoturbidimetry and high performance liquid chromatography (HPLC).

Special Biochemistry

Trace elements, metabolites, vitamins and various markers are analyzed by means of highly sensitive analytical technology such as immunoassays, HPLC or atomic absorption.

Breath tests are performed for the study of lactose and fructose intolerance and gastric infections.
