The CLSI order of draw, start to finish

Blood culture, light blue, red or gold, green, lavender, gray

First tube

Blood culture bottle or tube — drawn before anything that could break its sterility

Second tube

Light blue — sodium citrate for coagulation tests; fill to the mark for the 9:1 blood-to-additive ratio

Third tube

Red or gold — serum, with or without clot activator and gel; chemistry, serology, drug levels

Fourth tube

Green — heparin, lithium or sodium, with or without gel; plasma chemistry

Fifth tube

Lavender or pink — EDTA; CBC and blood films, pink for blood bank work

Sixth tube

Gray — sodium fluoride with potassium oxalate, a glycolytic inhibitor; glucose and lactate

Why the order exists at all

To stop additive carrying over from one tube into the next and altering the result

What EDTA carryover does to a chemistry result

Falsely raises potassium and drops calcium — so EDTA tubes follow the chemistry tubes

Why the citrate tube goes before the serum tubes

Clot activator shortens PT and aPTT; only cultures or plain tubes may precede the coagulation tube

Why the gray tube goes last

Fluoride and oxalate distort cell shape on a differential, so lavender is drawn before gray

A mnemonic for the order

Sally Brings Really Good Grease and Leaves the Gravy — sterile, blue, red, gold, green, lavender, gray

Who sets the order of draw

CLSI — its venous blood collection standard GP41, 7th ed., republished as PRE02, 8th ed.

When a discard tube is needed

When the citrate tube comes first through a winged set — it fills the tubing's dead space

Order of draw for a skin puncture

Reversed — EDTA for hematology first, other additives next, serum last (CLSI GP42)
