Hi Karen,
I'm an expat Tasmanian living in Canada. If I get a sample done shortly I
will probably use
and get a 21 test rather than a 12.

Now I will get to my question:
I cannot afford to get any testing done at present however I have two
relatives who are in late 70's and I would like to obtain samples now and
preserve them.

What is the best way of getting samples that can be used for the longest
period of time?

I notice that use a inside cheek scrapings but place it in
a fluid, once they get the sample they keep the sample indefinitely under
refrigeration in case you want further testing done later. This begs a
futher question.

Why can't I use a similar process to obtain a sample and keep it in my
refrigerator sealed etc. Obviously there will be times when it will be
unrefrigerated for periods of time but from the information I am hearing is
that the odds are that such a sample could in theory be preserved for
decades at least.

I am sure there must be many on this forum who can answer these questions.
