Blood specimen collection and processing
composition
Plasma (55%)
The light yellow, transparent and clear liquid that is separated out after the blood naturally coagulates is called serum.
Missing ⅠⅡⅤⅧ, containing Ⅸ, Ⅹ, Ⅺ, Ⅻ
The light yellow, transparent and clear liquid that is separated out after adding anticoagulants to the blood is called plasma.
tangible components
blood dust
Blood cells (45%)
red blood cells (RBC)
White blood cells (WBC)
Eosinophils (E)
