Abstract

The applicability of clinical laboratory robot LAS-2000A for screening kits to detect anti-HIV and anti-ATLA antibodies in the sera from hospitalized patients using the gelatine particle agglutination method was compared with manual operation. There was very little reagent loss during the experiment with either procedures. Processing was much faster with the LAS-2000A, but the titer of the positive sera was about 1 log2 unit higher than that with the manual operation. This difference appeared to be due to inadequate serum dilution process with the LAS-2000A. Although LAS-2000A requires improvement in the dilution process, it is very useful with respect to economy of labor and protection of laboratory staff against infection diseases.
