 AB    OBJECTIVE: To evaluate the usefulness of the HIV-related informations at
       a commercial laboratory in view of HIV epidemiology. METHODS: Number of
       anti-HIV tests, number of anti-HIV positive cases by screening test
       (EIA) and/or confirmatory diagnosis (Western blot, WB) during '87-'93
       were surveyed at a commercial laboratory located in southern Tokyo
       metropolitan area. RESULTS: Order for EIA test has started to increase
       in '91 and continued so thereafter. Number of anti-HIV positive cases,
       all confirmed by WB, jumped from '90 to '91 with a shift of dominant
       gender* from male to female, further increased in '92 but slightly
       decreased in '93. Proportion of WB-positive cases, remained below 0.05%
       during '87-'90, increased to around 0.1% in '92-'93. It was revealed
       that orders for WB were given from only 30% of all screening
       test-positive cases every year. TABULAR DATA, SEE ABSTRACT VOLUME.
       DISCUSSION AND CONCLUSIONS: Well corresponding to the recent findings in
       the HIV/AIDS Surveillance of Japan, commercial lab-based data appeared
       useful to reinforce the observation by the Surveillance. Comparison of
       the data between multiple laboratories would be useful in view of
       regional epidemiology of HIV.
