Re: [GIWorld-Hepatitis] Digest Number 89
- the PCR is an RNA test. sometimes they write it PCR-RNA and other ways. I
don't want to get real technical... but if you remember from science class..
DNA and RNA... i think the RNA was the messenger for the DNA or something
like that don't quote me I just woke up ahha. No one has seen an HCV virus.
Even the strongest microscopes cannot see ONE virus cell. What they can see
are the results and byproducts and doohickeys of the virus. Maybe that's why
even the best PCR tests can only test down to 200 parts/mil or something
Anyway.... pretend the scientists are aliens and they are looking for life
on earth... Now we as humans are too small for them to see like the hcv
virus... But... they can see our highways because they stretch all over the
continent (pretend they are the blood vessels). So they can do tests on the
highways to see the habits and actions of us the humans. They can test for
exhaust fumes from our vehicles, wear and tear on the roadways, that sort of
thing. That's a silly analogy but about what scientists sometimes have to go
thru to study really small things.
