TEST ORDERING PATTERN AT THE CHEMICAL PATHOLOGY LABORATORY, HOSPITAL UNIVERSITI SAINS MALAYSIA

Abstract

The utilization of the chemical laboratory resources at the Hospital Sains Malaysia was evaluated. More than 100,000 test requests received and performed over a 12- month period, were analyzed retrospectively. The analysis conducted included the abnormal results obtained, the degree of duplication of tests, and the extent of test-panel ordering. It was found that a relatively moderate degree of over-ordering was evident. The findings suggested that the main reasons for over-ordering were the use of panel tests of ordering, in addition to a small, yet significant degree of duplication. Strategies for cutting down the test ordering have been reviewed and discussed.
