Fig 01- Machine to detect virus infection and measure antibody concentration
in the blood (credit to Abbot)
As
of previous post, we talked about method to half spreading of
Covid-19 is better by lock down or physical (social) distant than
herd immunity:
We
might intend to avoid “lock down or physical (social) distant”
rule. How? Should We Get Covid-19 Antibody Test to Avoid Lock-down?
Antibody
test also called as:
-
immunity
titer
-
antibody titer
-
serological test.
It
is
a test to measure IgG and IgM antibodies where they are detected in
the blood after exposing
to the virus, in this case SARS-CoV-2 virus.
IgM
refers to antibody caused by recently infection, whereas IgG antibody
is formed after 7 to 10 days infection. IgG antibody may include
currently and past infections.
We
have success to conduct similar titer tests to following communicable
diseases:
-
mumps
-
rubella
-
varicella
-
measles
-
hepatisis B
Moreover,
New York state have recorded that 13.9% of 3,000 tested residents are
positive for SARS-CoV-2 antibodies.
What
is it mean?
If
this percentage hold to the whole nation, there are projected of 46
million of USA citizens have IgG and IgM antibodies to protect them
from Covid-19 infection in the future.
These
people may avoid stay at home order or even doing:
-
normal job in the offices as usual.
-
high risk jobs to take care Covid-19 patients
-
customers services
Do
you think antibody test is useful? Do you want to be tested?
