Clinical Laboratory

Introduction

The division consists of clinical pathology laboratories, a physiological laboratory and anatomical pathology laboratories.  There are five clinical pathology laboratories devoted to bio-chemistry, serology, hematology, urinalysis, and bacteriology and blood banking. The physiological laboratory consists of four sections in which ultrasonography (US) electrocardiography, electro-encephalography, and respiratory function tests are performed. Three staff physicians and 2 technicians manage these sections. These laboratories assist clinical activities of physicians and surgeons by providing reliable data rapidly.

The anatomical pathology laboratories, staffed by 3 consultant pathologists and 5 technicians, deal with surgical, cytological and autopsy specimens. All the data gathered by this section are computer-filed, and accessible to physicians at any time.

Routine Activities

The clinical laboratory division has 6 doctors, 17 technicians and 2 assistants. Data quality control and laboratory management are discussed in monthly meetings attended by doctors and the chief tech-nicians. Several weekly conferences in each section are held to monitor data quality control.

The most important role of the clinical pathology laboratories is rapid and highly reliable data provision to support prompt therapeutic decision makings by doctors. We employ a bar-code system for specimen identification and an automatic analyzing system.

The bacteriology laboratory plays an important role in infection control at the hospital, reporting not only routine data but also monthly, quarterly and yearly statistical data of hospital infections. We have introduced MGIT, a new culture system for acid-fast bacilli to provide rapid data, which are active in the control of hospital infection.

The roles of the blood banking section are typing blood, screening for irregular antibodies, and supplying blood at the request of doctors.

In the physiological laboratory, US is an important screening examination for malignancies in the neck and abdomen. Cardiac US provides valuable information on preoperative patients with cardiac disorders and on patients who underwent chemo-therapy with cardiac toxicity. The US filing systems have been introduced.

The anatomical pathology laboratories are engaged in the routine works of evaluating surgical, cyto-logical, and autopsy materials, and lab personnel are responsible for making histological and cytological diagnoses. To examine specimens in detail, immunohistochemical approaches and/or genetic analyses are frequently employed.
