A blood test for syphilis does not detect the bacteria directly, but rather the antibodies that the immune system produces in response to infection with Treponema pallidum.
Antibodies to Treponema pallidum are immune proteins that the body produces in response to infection with Treponema pallidum, the causative agent of syphilis.
Antihelminth antibodies are not a single, universal test for all parasites, but a group of different serological tests that look for an immune response to specific parasites or a limited set of their antigens.
A rapid (spot) or express HIV test can be performed outside of specialized laboratories, does not require any equipment, and provides results in a maximum of 30 minutes.
The risk of contracting infectious diseases transmitted by insects is quite high, even if the tick was removed quickly and was unable to penetrate deeply.
