red topped tube
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.
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.
The color of the tube for electrolyte testing is typically green.
draw tube holds the eyepiece or the ocular
Gray tube
In the NHA book it is written that Green top tube is for STAT electrolytes.
A false depletion in the electrolytes. The depletion of sodium will not be accurate.

What color tube for blood draw for metal
For a HgA1c you would need a lavender top tube.
