In 2014, the Central Laboratory and Clinical Lab were merged into the Lab Center, which passed the ISO15189 in 2016. In 2019, it was awarded the Clinical Laboratory Quality Demonstration Laboratory in Zhejiang Province from 2020 to 2022, and became the first batch of PCR demonstration laboratories in China. It is a training site for pediatrics graduate students of Zhejiang University, meanwhile, it accepts internships for fellow students from various provinces and cities across the country and graduates from medical schools, and hosts national and provincial continuing education classes.

The Lab Center currently employs more than 100 employees, including 1 doctoral supervisor, 5 senior titles, and 9 deputy titles. There are 6 professional groups in this center, including routine clinical examination group, biochemistry group, immunology group, microbiology group, molecular diagnostics group and blood bank and blood gas group. It has carried out more than 500 detection items, involving pediatric infection, genetics, blood, digestion, breathing, heart Vascular diseases, pediatric tumors and other related diseases, making contribution to a total output value of over 220 million yuan in 2019.

The center attaches great importance to the close integration with the clinic, and has established a laboratory featuring children's medical tests, which have a higher influence in molecular diagnosis of pediatric diseases, microbiological examination, experimental diagnosis of hemolytic diseases, flow cytometry and molecular diagnosis of leukemia lymphoma and solid tumor in children. The center has established a quality management guarantee system based on the ISO15189 medical laboratory standard. At the same time, the center actively carried out scientific research on clinical pediatric diseases, a total of 13 projects were approved by National Natural Science Foundations, and more than 120 SCI papers were published in past years.

Molecular diagnosis of pediatric diseases: The earliest clinical detection by PCR technology in Zhejiang Province was carried out in 1991; a fluorescent quantitative PCR instrument was introduced in 1998 to led the development of fluorescent quantitative nucleic acid detection; the certification of the Clinical Laboratory Center of the Ministry of Health was passed in 2003, becoming the first batch of PCR Demonstration laboratory. In 2004, a molecular genetics laboratory and a gene chip laboratory were established to carry out molecular cytogenetics and gene chip research and clinical work, to conduct diagnosis and research on children's infectious disease pathogens CMV, EV71, EB, and bacterial DNA, and at the same time, to carry out Pathogen antibody test.

 Blood and tumor flow cytometry and molecular diagnosis: Use color flow cytometry for immunological diagnosis of leukemia, lymphoma and childhood solid tumors and molecular genetic technology for disease diagnosis.

Diagnosis of hemolytic disease: Focus on the quality control of coagulation factor detection, and guide clinical diagnosis and treatment of hemolytic disease.

At the same time, the children's growth and development process and disease-related items such as hormones, allergens, trace elements and so on were tested and the molecular genetic diagnosis of congenital diseases was made. The tandem mass spectrometry technology was used for screening and clinical detection of more than 30 genetic metabolic diseases. Fluorescence in situ hybridization (FISH) was used to diagnose Williams Syndrome (WS) and 22Q11 microdeletion syndrome, and the diagnosis of fragile X syndrome was also carried out, and the pathogenesis and pathological mechanism of pediatric diseases were studied clinically.
