What happens if you underfill a tube with blood?
Conclusions Underfilling of tubes leads to a higher proportion of blood aspirated with high velocity and relevant elevations in LD. This finding should be considered in cases of clinically implausible elevated LD activities.
Why is EDTA tube used for CBC?
Anticoagulants are used to prevent clot formation both in vitro and in vivo. … Historically, EDTA has been recommended as the anticoagulant of choice for hematological testing because it allows the best preservation of cellular components and morphology of blood cells.

Green Tube/Plasma: Centrifuge after collection.
What order should Lab tubes be drawn?
The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.
What color tubes are drawn last?
1. Collect citrate tube (blue top) last, after 20mL of blood has been withdrawn for other testing, or as waste. Just prior to drawing the blue top tube as the last tube, draw 1mL into a discard blue top tube to prevent cross contamination from the additive of previously drawn tubes. 2.
How do you draw a CBC and CMP?
In review if you are to drawing a CBC, CMP and PT/INR for your patient, you would draw a blue tube first (PT/INR), followed by a tiger or gold top (CMP), followed by lavender top (CMP).
What is the purple top tube used for?
The purple top tube provides blood for infectious disease tests and ascertaining important data such as ABO/Rh (blood type), as well as whether the blood is positive or negative for cytomegalovirus (CMV), HIV, hepatitis, and West Nile virus, to name a few.
What is a blue top blood test?
Blue top tube with 3.2% sodium citrate: used for coagulation testing and other plasma or whole blood determinations. If only a coagulation specimen is being drawn, draw 1-2 mL into another blue top (3.2% sodium citrate) tube, discard, and then collect the specimen.
What tubes are used in hematology?
In general, hematology testing is performed on EDTA- (purple top tube) anticoagulated blood.
What is red top tube?
Red-top tube: Contains no anticoagulant or preservative. Use: Serum or clotted whole blood. … Mottled red/gray-top, gold-top, or cherry red-top (gel-barrier) tube: Contains clot activator and gel for separating serum from cells, but not anticoagulant.
What is a rainbow draw lab?
Clinical laboratories often receive extra blood tubes beyond what is needed for associated laboratory test orders. Sometimes, this practice involves drawing tubes of every possible color (the “rainbow”) to allow for add-on testing at a later time.
What happens if a gray tube is underfilled?
If tubes are underfilled, the blood:anticoagulant ratio may result in hemolysis. Avoid underfilling tubes by having an ample supply of tubes of various capacities.
What happens if a sodium citrate tube is underfilled?
Underfilled sodium citrate tube. Citrate distributes only in plasma and if a tube is underfilled, the reduced plasma volume will contain more citrate anticoagulant, leading to increased calcium chelation (see citrate tubes A–E).
What happens if you draw blood in the wrong order?
Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. During syringe collections, contamination with K EDTA may rarely occur if order of draw is not followed.
Can heparin be used for CBC?
No negative effects on morphology and staining of blood cells were apparent in smears from heparin samples compared with K2EDTA samples. Within the different values compared, the limits of agreement are small enough to be confident that lithium heparin can be used for routine CBC counts in a clinical setting.
What is the difference between EDTA and heparin?
EDTA and citrate remove calcium, which most coagulation factors need. Heparin activates antithrombin thereby inhibiting coagulation by inhibiting thrombin. … Heparin is used for clinical chemistry tests such as cholesterol, CRP, hormones etc. It interferes with PCR, so if you want to do that use EDTA.
What is a EDTA blood test for?
An EDTA test is used to assess the function of your kidneys through a series of blood tests. EDTA refers to the name of the substance that you will receive by injection. EDTA contains a small amount of radioactive material. This allows it to act as a tracer which will show the kidney function.
What is RFT and LFT test?
Kidney Function Test (KFT/RFT Test) is a profile of biochemistry blood tests that are useful to assess the renal function. KFT test is also commonly known as Renal Function Test, RFT Test, Kidney Profile or Kidney Panel.
What color tube is used for ammonia blood test?
Lavender-top (EDTA) tube; EDTA is the only acceptable anticoagulant.
What color tube is PTT?
Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. Evacuated collection tubes must be filled to completion to ensure a proper blood-to-anticoagulant ratio.
What is the code for blood sugar test?

What is the correct code for a blood glucose level?
From a CPT coding perspective, code 82948 describes a blood glucose level that is determined by a reagent strip method. The blood is obtained and a drop of blood is placed on a glucose oxidase strip.
Which of the following stopper colors identifies a tube used for coagulation testing?
2. Light Blue Top (plasma): 3.2% sodium citrate. These tubes are used for coagulation tests and need to be completely filled to ensure the proper ratio of blood to anticoagulant.
