What is seropositivity? How is it used in calculating/interpreting infection rates?
In: Biology
Seropositivity refers to having antibodies circulating in your system for a pathogen specifically. It does not indicate infection level, instead, indicate how concentrated is the quantity of antibodies.
A typical antibody test is done centrifugating your blood, taking the serum, and testing it against a test that determines a specific concentration. 1:1 means they dilute 1 part serum, one part water, and test it again. Higher the number, higher the concentration found. 1:2 is one part serum, 2 parts water and so on.
