You can get special caps which don't seem to come off to reseal
vacutainer bottles.
We use these a lot as we draw blood with the vacutainer system for POC
testing and then send the bottle to the lab for storage of the rest of
the sample in case we need additional tests.

Taking the lid off to fill the tube is unpopular with the labs as the
tube then has a high probability of leaking.

Our laboratory advises us to the contrary. It is felt that using a
needle
to 'inject' the rubber stopper represents a safety risk as one might
inadvertently inject one's own finger. I have been advised to use the
vacutainer system where possible and, if using a syringe, to remove the
vacutainer cap and squirt blood in without a needle, up to the line.
I have to say that I have found haemolysis to be a very rare occurrence
when
using the vacutainer system, from a freshly placed or old canula, so
long as
one discards the first container drawn.
On a related note, I have found when using the needle-less Vygon system
that
one must usually draw a small syringe-full of blood (which I then
discard),
prior to being able to withdraw blood using the vacutainers. I presume
this
has something to do with the sealing system and needing a certain amount
of
vacuum to overcome it.

snip.
our labs types say if you must take blood with a syringe and needle,
try
and use a green needle and then let the vacutainers 'suckup' the correct
amount fro mthe syringe , i.e. don't 'inject' into the bottle or pop the
'cap 'off and squirt some blood in
snip.
