The feasibility of screening for antibody to HIV by pooling 10 serum specimens was demonstrated in this experiment. The test was conducted using the reagent developed by Organon Teknika corporation (U. S. A) for testing for antibody to HIV by ELISA. The determination was made by changing only the ratio between the serum specimen volume and the serum specimen diluent volme, with their total volume being constant. When the serum specimen volume was increased from 5to 59?l as a result of pooling 10 serum specimens, while the serum specimen diluent volume was correspondingly decreased, the optical density of the pooled serum specimens was somewhat raised, but it was always below cutoff value, indicating that the specificity of test did not be subjected to any influence. In addition, when one serum specimen estabished as being positive intesting for antibody to HIV, and nine serum specimens from normal donors were pooled, the serum specimen containing the antibody to HIV had exactly been shown through multiple paired tests, indicating that the serumpooling method did not have any influence on the test sensitivity and could reach the level of original method. The serum-pooling method could be easy to spread because of its many advantages, such as saving the expenditure by 10 times, saving the manpower and material resource, and saving the working hours.
