Advanced two-part closure design guarantees a perfect fit between outer plastic cap and inner rubber stopper. Mediplus Multiple Needles are predominantly used in routine blood collection and are exclusively single-use. The bottles used for measuring a common biochemistry test called U+E (urea and electrolytes, which includes potassium measurement) do not contain this anticoagulant.
However, it can be a bit more subtle than this if you transfer just a small amount from the FBC tube to the U+E tube.
The closure can be easily removed and does not cause blood spillage, which ensures complete safety during collection and testing process.

The colour of the needle protective cap simplifies visual recognition of the individual types. EDTA is an anticoagulant which prevents the blood from clotting so that the cells can be counted in a machine. If you were to tip some of the blood from the FBC tube into the U+E tube you will tip some potassium EDTA into the U+E tube. This can occur if you are using a needle and syringe technique to take the blood sample and pierce the bung at the top of the FBC tube with the needle first to put some blood into that tube followed by then piercing the bung at top of the U+E tube. If it does happen then clues to contamination being the cause are an unexpected change in the patient's potassium result (!) and a couple of biochemical clues.

This will result in a falsley elevated potassium level - usually to a value obviously incompatable with life!
Clue 1 - the EDTA chelates calcium so measuring the calcium on the U+E sample will show a very, very low calcium.
Zinc is required for the enzyme alkaline phosphatase to work so we can measure this enzyme in the lab.
