blood test is the very basic diagnosis
any pathogen for that cause has only two options to enter the body ( external and internal)
external - skin
internal - endoderm

our body is maximum occupied by two things that is either blood vessels or nerve cells

if any pathogen has to enter the body it should either go through blood or through nerve cells

usually blood is the main transportation for pathogen

like when a doctor has to inject vaccine he has to make it through blood

so for any diagnosis of diseases blood test is the primary way
