The Six Sigma test certificate is certified by the US Westgard QC in accordance with international standards. Nearly 50 laboratories around the world are awarded this certification, for which errors in test results must be minimal, with less than four errors in a million occurrences. The testing unit of Cho Ray Hospital is the first public hospital in Vietnam to achieve this certification, with 75% of the tests satisfying the criteria for Six Sigma.

Associate Professor, Dr. Nguyen Truong Son, Director of Cho Ray Hospital, said that the unit is always facing an increasing number of tests due to increasing patient numbers. The results of tests ensure 60-70% of clinical diagnosis by doctors, so assuring the quality of test results in the shortest period of time while maintaining quality standards and economic efficiency is a huge challenge.

The automated testing system operated at the centre since mid-2016 has helped shorten about 55% of workflow, increasing productivity, reducing testing result return time, and sharing the burden with other departments. The system has the fastest conveyor at present, with a rate of 3,600 samples per hour.
