The Department of Parasitology, formerly known as “Parasitology”, was initially a unit of the Department of Pathology. Parasitology is the study of diseases caused by parasites in other living organisms, such as humans, and the study of relationships between hosts and parasites. Parasitology is, therefore, considered an essential subject in the study of medicine. The National Education Council decided to isolate the Department of Parasitology  from the Department of Pathology on January 10th 1967, with Professor Dr. Arnon Pratatsunthornsarn appointed as the first Head of Department.

Vision 

The Parasitology Laboratory is committed to developing an excellent service of international standards to provide patients with accurate diagnoses and timely services. Our priority is to ensure that patients are confident and satisfied with the quality of our services. 

Mission

The mission of the Department of parasitology is to provide standard, trustworthy, and quality services meeting international standards. 

The Department of Parasitology is divided into four sections as follows; 

1. Patient services.
2. Academic services.
3. Education and research.
4. Administration. 

Services

For the patient services, The Parasitology Department has broken down the disease examinations service into two subdivisions as follows;

1. Parasitic disease examination services at 14^th Floor, Bhor Por Ror Building, .
2. Parasitic Lab examination services. 

The Parasitology laboratory can be divided into 

• Parasitology Laboratory, 4th Floor, Bhor Por Ror Building.
  Outpatient services and general health checkups for patients going abroad.
  
  
• Parasitology Laboratory, 3rd Floor, Bhumisirimangalanusorn Building.
  Providing inpatient services and health examinations. 
  
  
• Parasitology Laboratory, 18th Floor, H.M. King Ananda Mahidol Building.
  Providing examination services that require special techniques, including cultures, dyeing, immunological testing and molecular biology examinations.

The Parasitology Laboratory

The Parasitology Laboratory provides testing services that can be split into six main categories with a total of 27 tests as follows;

1. Diagnosis by parasitological methods including;

1. Routine stool examination.
2. Blood filariasis testing via Giemsa stain or the DEC provocative test.
