Anticoagulant
A chemical that keeps blood from clotting
Light Blue
No additive tube
The blood will clot in centerifugation
Red
Additive Tube
Improve the quality of the specimen or accelerate specimen processing
Serum Separator Tube (SST)
Gold
Contains a gel which accelerates clotting
DOES NOT CONTAIN FIBRINOGEN
Plasma Separator Tube (PST)
Accelerates clotting and CONTAINS FIBRINOGEN (a protein involved in forming blood clots in the body)
Light green and tube contains lithium heparin
Test for electrolytes levels
Blood Cultures
1st order of draw
Aerobic(with air)blue top
Anaerobic (without air) purple
Blue Top
2nd in order of draw
Contains sodium citrate
Coagulation test PT(prothrombin time) a test to see how fast the plasma clots
PTT(partial thrombin time)
Red Stopper Tube
Contains no additive 3rd in draw
Serum test
HIV, Blood Type, Drug levels,
Goes first before blue top when using a butterfly and not using blood cultures the tubing line in butterfly has air in it
Also a discard tube
Red grey
Gold top tubes, also known as serum separator tubes (SSTs), are used for a variety of tests that require blood serum. The tubes contain a gel that separates the serum from blood cells after spinning, which makes them ideal for tests that need serum quickly.
SST Red Grey Stopper
Contains glass particles thixotripic gel
It test serum, PSA, lipids,thyroid, and Chemistry
Green PST tube
Plasma separating tube it contains lithium heparin
Test all chemistry test like SST’s
PST contains fibrogen
Dark Green
Contains sodium heparin
It’s a anticoagulate
Chemistry studies like electrolytes B&P(basic metabolic panel) or a CMP (comprehensive metabolic panel)
Purple or lavender top tube
Contains EDTA
Hematology
CBC ESR(testto see how fast red blood cells go down the tube) HCT(measures the the percentage of red blood cells) RBC WBC HGB(measure the amount of hemoglobin)
Gray top tube
Contains sodium fluoride which is a antiglyocytic
Test the standard glucose level test
Yellow tubes after gray top contains citrate dextrose
It test for tissue typing paternity test and DNA studies
Royal blue after gray tops
Main contain heparin commonly a element free tube
Specialized, testing and toxicology testing
Invert
Invert gently 3 to 8 times in correct order of draw
Invert
Invert gently 3 to 8 times in correct order of draw
