COVID-19 laboratory workflow chart in Peking University People’s Hospital (PKUPH). The bottom two rows represent the time spent in the whole process on the basis of the daily quantity of tests performed: 2000–3000 and 4000–6000, respectively. The orange figure represents the person being screened. The dashed box indicates the testing process of the nucleic acid testing laboratory, including specimen reception, reagent preparation, nucleic acid extraction, gene amplification, and release of results. The green frame represents that the specimen has been matched to a serial number from the batch of 93 samples before entering the laboratory, reducing the time required to receive specimens in the laboratory. Once the testing results were released, the hospital’s health information system platform quickly released the results on public platforms including Wechat, Beijing Jiankangbao, and PKUPH, making real-time test results available via cell phone.
