A member asked:

How many different ways can a pathogen be detected? is 1 way better then another for all pathogens? example: antibody-antigen-dna/rna-proteins..?

A doctor has provided 1 answer

Many: A pathogen is any micro-organisms that causes disease. We find different pathogens by different techniques -- prions (which count as pathogens) only by chemistry, many by polymerase chain reaction, seeking antibodies, growing them (most bacteria, some viruses), or seeing them under the microscope. There's no one-size-fits-all.
