Tube Info/Order of D

Edumed phlebo tube info/order of draw

QuestionAnswer
Chemistry Basically all other test. Where order of draw is very important. Ex of tests: glucose, Ca, Na, Cholesterol, Bilirubin, Myoglobin, CMP, BMP STAT tests in Grey top tube, Royal blue top tube for heavy metals, SST tubes
Microbiology Sending specimen to see if anything grows on petri dish. STERILE YELLOW top tube.
Immunhematology Blood bank - looks at blood typing, ABO Rh, and transfusions Plain red or pink tube
Coagulation Tests for clotting factors. Test: (PT)/INR, PTT Light blue top tubes.
Hematology "Study of blood" looks at shape and number of cells Used Lavender EDTA tubes for this since they don't clot. CBC, H&H
Light Blue Top Tube Anticoagulant Sodium Citrate, binds with Calcium in order to keep blood from clotting. Must fill completely in order to get 1:9 ratio Used for coagulation tests. Common test: PT, APTT, PTT, INR.
Red Top Tube Can be glass or plastic. Glass used for blood banking and drug tests. NO Anticoagulant, WILL CLOT. Used for Chemistry Tests
SST Thixotropic gel, will clot. Serum Separator tube, Tiger, red/grey marble, gold. Used for Chemistry Test. Clots faster due to clot activator.
Grey Top Tube Anticoagulant= potassium oxalate which binds Calcium. Glycotic inhibitor = sodium flouride = prevents metabolism of glucose by RBCs. Goes to Chemistry. Used for glucose and Blood alcohol testing.
Green Top Tube Anticoagulant Sodium Heparin, lithium heparin or ammonium heparin. Heparin stopping blood from clotting by inactivating thrombin and thromboplastin. Used on STAT chemistry procedures and ammonia levels (on ice)
Lavender Top Tube EDTA, Ethylene-diaminetetracetic acid, will not clot. Binds to Calcium in order to keep blood from clotting. Used for Hematology testing. Common tests: CBC, Hemoglobin A1C, bilirubin.
Order of Draw List - Venipuncture 1) Yellow 2) Light blue 3)Plain Red 4) SST 5) Green 6) Lavender 7) Grey
Order of Draw List - Capillary Puncture 1) Lavender and slides 2) Green 3) Gray 4) Red
Hemolysis Destruction of red blood cells, avoid by choose correct needle/tube size. Common causes: leaving the tourniquet on longer than 1 minute, shaking the tubes, not allowing the tubes to clot before spinning or patient fist pumping
Calcaneous Bone in foot to avoid when performing dermal punctures
Dermal puncture maximum depth? 2mm
Hematocrit collected to see percentage of packed Red Blood Cells
What patients would you perform dermal puncture on? Children under 2 years of age, severe burn patients, chemotherapy patients, older patients, for glucose monitoring
Which fingers should you use for capillary punctures? Digits 3-4
What do you after piercing skin with lancet? Wipe away the first drop of blood
Why would you choose a dermal puncture over venipuncture? If only a small amount of blood is needed. Using capillary blood
Yellow Top Tube Sterile - used for blood cultures. Goes to microbiology. Contains SPS and ACD. Use sterile gloves to prevent contamination and clean with Providine or Betadine.
Royal Blue Top Tube Used for Heavy Metal Testing
Light Green Top tube PST- plasma separator tube.
Common blood thinners? Coumadin or warafin. Should not be aspirin regiment and will have blood drawn every 2 weeks to check levels. (Lt blue tubes)
