It also operates as a teaching and training hospital for the medical and nursing students of Li Ka Shing Faculty of Medicine of the University of Hong Kong.

It was originally opened as a maternity hospital, with the intention to meet society's increasing demand for neonatal services, including the training of midwives and obstetricians.

The London Missionary Society recruited the first foreign female doctor in Hong Kong, Dr. Alice D. Hickling, and appointed her as the director of Tsan Yuk.

In her development of obstetric services, she quickly recognised the abundance of women eager to become professional midwives in Hong Kong, and had the notion to provide such training through the hospital.

Three years later, on 13 June, Sir Alexander William George Herder Grantham held the opening ceremony for the new Tsan Yuk Hospital.

Funded by donations from Mrs Wu Chung and the government, the laboratory was set up to screen pregnant women for possible congenital diseases or abnormalities in their babies.

To ensure that the laboratory's testing procedures and results meet international standards, the centre was enrolled in the Royal College of Pathologists of Australia Quality Assurance Programme in cytogenetics.

In March 2000, the Integrated Clinic of Hong Kong West Cluster commenced operation in Tsan Yuk Hospital providing comprehensive and holistic care for patients with stable chronic illnesses.

In the interests of quality and cost effectiveness, the obstetric and newborn inpatient services provided by Tsan Yuk were relocated to Queen Mary Hospital in November 2001.

Tsan Yuk Hospital also conducts a variety of health education programmes for their patients, including such areas as care of newborns, dietary requirements of pregnant women, and family planning.

It refused to check the records due to privacy reasons but agreed to offer DNA tests for the people born on the same day at Tsan Yuk Hospital.

Chuk Yuen Children's Reception Centre was also a potential lead in solving this case of wrongful identity, where the woman Mr. Li knows as his mother left her baby for a month.
