red topped tube
Both time and temperature can decrease the vacuum draw of an evacuated tube. Hence the provided expiration dates and storage temperature of tubes. The vacuum of a tube will decrease if it is too old or if stored at a colder temperature than recommended.
Fill a syringe with the STAT electrolytes first Next, draw the CBC routine tubes Then, collect the sample for creatinine Lastly, draw the tube for protime testing
Stat electrolytes are typically drawn in a green-top (heparin) tube, or sometimes a red-top (serum) tube for urgent testing. These tubes contain anticoagulants or clot activators to preserve the integrity of the sample until testing.

red tube
The lavender top tube contains EDTA anticoagulant which can bind to calcium ions, affecting electrolyte results. Drawing a lavender tube before electrolytes can lead to falsely decreased calcium levels and potentially inaccurate electrolyte results. It is recommended to draw the lavender tube after the electrolyte tube to prevent any interference.
For a HgA1c you would need a lavender top tube.
because if it was heated in open air it would burn up

The color of the tube for electrolyte testing is typically green.
