Infectious Diseases


Department of Infectious Diseases and Clinical Microbiology offers outpatient and inpatient follow-up services for patients presenting with complaints of fever and/or other signs (diarrhea, jaundice, rash, dysuria, sore throat, cough, secretion and joint ache etc.) and provides inpatients of other departments with consulting services.

Routine patient evaluation at our outpatient clinic is supplemented by immunization of adults, pre-transplant infection screening, hepatitis and infection prevention counseling before overseas travels. Moreover, our department treats and follows up infections that emerge in patients who stay at intensive care units and inpatient clinics. We aim early diagnosis for adult patients with infection through means of modern medical knowledge and technology to ensure efficient treatment of infections; people presenting for prevention of community-acquired infections (hepatitis, AIDS, sexually transmitted infections etc.) are provided with information and immunized, while the risk of hospital-acquired infections is minimized.

The Clinical Microbiology Laboratory that is affiliated to our department offers laboratory services to outpatients and inpatients round the clock. Principles of total quality management are strictly observed, while patient specimens are accepted to the laboratory and processed and results are reported. All antibiogram tests performed in our laboratory fulfill recommendations of EUCAST (European Committee On Antimicrobial Suspectibility Testing) that is updated every year. Bacteria culture, antibiogram tests, tuberculosis staining, culture and susceptibility tests are checked at monthly intervals over an international external quality control system. There is also a Molecular Diagnosis (PCR) Laboratory, where viral agents are investigates, in the Microbiology Laboratory. Our Laboratory also deals with andrologic tests and also sperm wash and preparation for insemination before assisted reproductive technologies in collaboration with doctors of Gynecology and Obstetrics department. No specimen is accepted from third parties.
