1

general order of draw

1. blood culture tubes (yellow-black)
2. non-additive tube (red)
3. coagulation tubes (light blue)
4. additive tubes (in this order)
-SST (red-grey or gold)
-sodium heparin (dark green or brown)
-PST (light green)
-EDTA (lavender)
-ACDA or ACDB (pale yellow)
-oxalate/fluoride (light grey)

2

additive in red top

none

3

MOA of red top

blood clots and the serum is separated by centrifugation

4

uses of red top

chemistries, immunology, serology (blood bank/cross match)

5

additive in gold top

none

6

MOA of gold top

serum separator tube (SST) contains a gel at the bottom to separate blood from serum on centrifugation

7

uses of gold top

chemistries, immunology and serology

8

additive in light green top

plasma separating tube (PST) with lithium heparin

9

MOA of light green top

anticoagulates with lithium heparin; plasma is separated with PST gel at the bottom of the tube

10

use of light green top

chemistries

11

additive of red-gray top

SST with clot activator

12

MOA of red-gray top

forms clot quickly and separates serum with SST gel at the bottom of the tube

13

use of red-gray top

chemistries

14

additive of lavender top

EDTA liquid

15

MOA of lavender top

forms calcium salts to remove calcium

16

uses of lavender top

hematology (CBC) and blood bank (crossmatch)

17

special note for lavender top

requires full draw and inversion 8x to prevent clotting and platelet clumping

18

additive of light blue top

sodium citrate

19

MOA of light blue top

forms calcium salts to remove calcium

20

use of light blue top

coagulation tests (PT and PTT)

21

special note for light blue top

requires full draw

22

additive of dark green top

sodium heparin or lithium heparin

23

MOA of dark green top

inactivated thrombin and thromboplastin

24

uses for dark green top

1. for lithium level: uses sodium heparin
2. for ammonia level: uses sodium or lithium heparin

25

additive of dark blue top

sodium EDTA

26

MOA of dark blue top

tubs is designed to contain no contaminating metals

27

uses of dark blue top

trace element testing (zinc, copper, lead and mercury) and toxicology

28

additive in large gray top

sodium fluoride and potassium oxalate

29

MOA of large gray top

actiglycolytic agent preserves glucose up to 5 days

30

use of large gray top

1. for lithium level: uses sodium heparin
2. glucose level requires full draw (hemolysis id short draw)
