Delisted GA

Hi. I have removed this article from the Wikipedia:Good article listing due to the following:

• No references. One of the GA criteria is that a reference section must be provided. Inline citations are preferred but not required. When this issue has been addressed, please feel free to re-nominate. Thanks! Air.dance 04:06, 25 March 2006 (UTC)

Per your comment on your talk page, I've relisted it. I also took the opportunity to add a references section. :-) --TreyHarris 05:11, 6 April 2006 (UTC)

Looks great and is GA material all the way. Sorry about the mix-up! Air.dance 05:15, 6 April 2006 (UTC)

Lithium Citrate?

Hi,

Just used your article for a session with a group of Trainee Biomedical Scientists in a Biochemistry Laboratory and noticed a possible mistake...

In the "contents of tubes" section the following line is present...

"The substances may include anticoagulants (EDTA, lithium citrate, heparin) or a gel with intermediate density between blood cells and blood plasma."

It is a sodium salt of citrate which is used as an anticoagulant and a lithium salt of heparin.

Other than that it is a great article.

Thanks —Preceding unsigned comment added by 62.6.139.11 (talk • contribs)

I changed "lithium citrate" in the above excerpt to "sodium citrate." I left heparin without a cation because the article later mentions a few different ones that are used. I don't really know what I'm talking about, and you seem to, so feel free to edit the article directly.  :) --Loudsox 21:58, 17 July 2006 (UTC)

Gel component

Does anyone know the gel component of the vacutainer? Which seperates serum and blood cell? Or any similar products which works the same?

1943 or 1947?

There seems to be a difference in dates for the vacutainer. In the Handbook of Phlebotomy and Patient Service Techniques, 4th ed by Garland E. Pendergraph, page 4 states "Little change occured in either instrumentation or concepts until 1943 when an evacuated blood collection system, known as the VACUTAINER Brand, had its beginning."

The wikipedia page begins by stating it was developed in 1947. That is all the book mentions about the vacutainer up to this point. And so since I don't have any conclusive evidence for the actual timeline of the vacutainer, I will just bring this to everyone's attention. DestinyQx 17:58, 1 February 2007 (UTC)

To this question,there is an answer on BD's homepage---"http://www.bd.com/aboutbd/history/".

Beside the number 1947,there is an explanation---"BD Vacutainer System Joseph Kleiner, hired by BD for his Multifit syringe with interchangeable parts, also brought with him a concept called the Evacutainer — a device to draw blood by vacuum through a needle into a test tube. The product, patented in 1949, evolved to become the BD Vacutainer Blood Collection System."

So I think It should be 1947.How about your opinion?
