The excessive spread of the pandemic COVID19 around the globe has put mankind at risk. The medical infrastructure and resources are frazzled, even for world's top economies, due to the large COVID19 infection. To cope up with this situation, countries are exploring the pool test strategies. In this paper, a detailed analysis has been done to explore the efficient pooling strategies. Given a population and the known fact that the percentage of people infected by the virus, the minimum number of tests to identify COVID19 positive cases from the entire population is observed. The analysis reveals that the tests needed are very less when compared to the total population. This can be looked as an essential step towards efficient utilization of sparse available resources of COVID19 testing kits, especially for the countries having limited medical infrastructure.
