The Chongqing Health Center for Women and Children (CQHCWC) held an online training session on neonatal screening on May 14, attracting the participation of 179 neonatal screening administrators and technicians from 40 district and county centers for women and children.

The event was themed with the "application of mass spectrometry (MS) techniques in screening for inherited metabolic disorders (IMDs)".

Doctor Zou Lin -- from the Children's Hospital of Chongqing Medical University -- gave a talk on the principles of MS techniques and some common types of MS techniques used in the clinic. Zou also shed light on the application of MS techniques in IMDs and discussed the current situation and future development direction of the applications in the field of neonatal screening in China and Chongqing.

Then, Doctor Miao Jingkun from the CQHCWC analyzed the clinical manifestations, causes and pathogenesis of various IMDs through case analysis, combined with the current actual situations.

A video of the training session has been made available on the internet for grass-roots medical institutions.

The training session, said CQHCWC officials, responded to COVID-19 prevention and control policy. And it also played a guiding role in the screening and diagnosis and treatment of IMDs, which is expected to boost CQHCWC's work as well as the neonatal screening techniques in Chongqing.
