Tube Info/Order of D
Edumed phlebo tube info/order of draw
Question | Answer |
---|---|
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) |
