Hello there...I can understand your concern. The seroconversion phase can vary in some individuals. Also it will depend on the generation of Elisa test done. 3rd and 4th generation Elisa can detect antibodies in a month. Whereas 1 and 2 will detect after 2 to 3 months. So ask him to repeat the test after 3 months of exposure.
