Collection ProceduresCâu 23 / 100
A phlebotomist has just filled a light blue citrate tube. According to the standard order of draw, which tube is collected next?
a.Lavender EDTA tube
b.Gray sodium fluoride tube
c.Green heparin tube
d.Gold serum separator tube
Giải thích
After the citrate tube, serum tubes with or without a gel separator are collected, followed by heparin, then EDTA, then the fluoride tube. Placing EDTA or fluoride earlier risks carrying potassium-containing or oxalate additives into chemistry tubes. Heparin also follows, not precedes, the serum tube in the standard sequence.
