The temporary halt on blood tests conducted by the Pathological Department of Klang’s Tengku Ampuan Rahimah Hospital (HTAR) only affects those done for instructional purposes and not for emergency or treatment purposes, said Selangor Health Department director Dr Zailan Adnan.

“Sometimes we have to reduce the number of tests. Some tests are part of the instructional process, for knowledge and to teach, some are for critical purposes such as for diagnosis of patients being treated.
