TZAM Diagnostics is set up by a group of gastroenterologist, pathologist and biologists. About 11 years ago, Dr Tat-Kin Tsang asked the question: If H. pylori are transmitted by oral-fecal route, why is it more often found in Asians, Mexicans and Africans. Therefore he found a research laboratory to target the area of transmission of H. pylori. His initial emphasis was frustrated by the difficulty in culturing the organisms.

      The research group suspected that foods might be sources or vehicles for H. pylori transmission. Because of the tedious culture technique and the inaccurate chemical analysis, the research group began to explore other means to diagnose H. pylori. With much intensive labor and effort, a novel multiplex PCR assay was developed in the lab. Later, the assay was applied in clinical research, and the result was plausible in its clinical applications in management and treatment of gastrointestinal disease.

      TZAM Clinical Laboratory now offers the test of Multiplex PCR for detection of H. pylori. TZAM continues to work hard in R&D. A new assay for H. pylori sub typing and another to detect C. Difficile by Multiplex PCR were recently developed. TZAM continues to contribute more novel molecular diagnostic assays to detect G.I. infection or other G.I diseases, and will continue to pursue the highest quality of services for patients and physicians.
