My research demands collecting a blood sample from children for mineral analysis. To this BD Royal bluetop tube (glass) is require. Unfortunately, I could not get such type of blood collection tube in the market here in my country. Is there any other type blood collecting tube use for mineral analysis?
(Which is replacing Royal blue top tube (glass)?)
Dear: Ashenafi
Other solution is use plastic tube more 10.8 mg/ml blood because is specification Royal tube.

The collection tubes are divided in three different types: i. for whole blood or plasma in which an anticoagulant solution (EDTA, Na citrate, Heparin) is present; ii. for serum with a clot activator; iii for serum without clot activator. All may contain a gel for plasma/serum separation. The Royal bluetop tube contains a clot activator, without gel separator. In the tuber for serum, the clot activation (usually thrombin) allows to centrifuge the samples in a shorter time after collection. If for you the delay between collection and centrifugation is not important you can use any other tube without additives. If this time is important you can use other tubes with clot activator. The colour top is not important and tubes from other manufacturer are are usable equally. If the tube must be transferred after centrifugation, a gel separator inside the tube is needed.

grey top and white label tube may be a good alternative as per quest diagnostic
Sorry, In BD catalog grey tubes contain fluoride/oxalate or EDTA/oxalate and are suitable for glucose only but not for other tests on serum/plasma
Antonio its not from BD its from quest diagnostic ,please go through the link above .
Antonio .please -no sorry. we are here to gain and disperse scientific knowledge . thanks
Certified trace metal free tubes are highly preferred for trace metal measurement (eg not iron).
This is because the plastics/separator/rubber cap manufacturing processes can lead to trace metal contamination of tubes - which may also vary from lot to lot.
You might be able to do a study of alternative candidate tubes, eg by adding either metal free fluid or a fluid you have previously measured trace metal levels in) to a candidate tube and seeing what the change occurs due to contamination. As mentioned, if a tube is not certified as metal free, you might need to do this with every production lot though so you don't mislead yourself into the future.
[In my experience, tube producers don't tell you of significant events like when they have shifted their production facilities from one country to another.]
