Dear all
We use BD Vacutainers, with SST tubes having a gold top.
During authorisation of results I identified a GP sample with sodium citrate contamination - turned out that the sample was sent in a Greiner tube (which has a yellow top).
I never did find out how this tube came to be in the system. Only this one tube ever surfaced.

I agree that the
current state of affairs is confusing, and that the
professions should take the lead in lobbying for
harmonisation. In the absence of an ISO standard, and
(for the UK people)
the fact that we are in Europe, I would suggest that the UK
should harmonise with the EU code. In the interests of
patient safety we should lobby the MHRA or the NPSA to send
out an alert to harmonise, allowing the laboratories and the
manufacturer time to
make the change.

In my view as a
profession we should take the lead. Marieke has outlined a
real problem and Jonathan has said that he found it very
confusing. How confusing must it be for our users? If we
agree
a standard then if a manufacturer refuses to supply it they
lose the business.
I have experienced
changing blood taking systems more than once and yes
it is disruptive in the first instance, but not for very
long. Any of the good tube suppliers who win new business
will
help put a training package together.
So in my view it can
be done. Whether the ACB or the RCPath or the IBMS should
take the lead, I am not sure, but they certainly need to
collaborate. Perhaps if one of those bodies was to conduct
a survey to find out which is the commonest system in use
in the UK that would be starting point.

I think
standardisation across the UK is a good idea in theory –
having trained in a trust that uses Greiner Vacuette tubes
that use the American colour code system to now working in a
trust
using Sarstedt Monovette tubes which use the EU colour
coding system, I got very confused in the early days,
particularly around green/orange and blue/green.
However, this kind
of standardisation would require the co-operation of the
tube manufacturers in producing tubes to ‘UK
specifications’ if it is the opposite of what they produce
as standard.
Additionally, standardising to a colour system that
resulted in the removal of a particular tube
type/manufacturer from the UK market could cause massive
upheaval in terms of staff training.
Whilst
standardisation of tube colour is most definitely desirable,
I doubt it is easily practicable.

Subject: Re: Blood tube colour conventions
Last year, there were
proposals to have an international (ISO / CEN) standard for
blood collection tube colours because this problem was
recognised [I am a member of the BSI committee
that deals with this sort of standard]. The UK was one of
the countries that voted in favour but as only 4 countries
in total were interested, the bid for a standard falied and
the work stream was dropped.
It may be that a UK
code of practice to standardise a colour code for the UK
could be organised through the College - and then have that
enforced by UKAS / MHRA...

Subject: Blood tube colour conventions
Dear all
With patients moving between
hospitals to have their blood samples taken, bringing
electronic request forms which list tube colour as well as
type, there is the possibility of wrong sample types
being taken if phlebotomists go by the colours that they
are familiar with. We are looking at standardizing colours
regionally.
It appears that around here the
system most frequently in use is the American convention
(red for clotted, gold for gel, green for heparin, grey for
glucose, mauve for EDTA, blue for coag).
However, the other colour code
commonly in use, is the EU code (clear for clotted, brown
for gel, orange for heparin, yellow for glucose, red for
EDTA, green for coag).
Any thoughts on which we should go
for?
Regards
Marieke
