What is the order of collection when you use capillary puncture?
Take laboratory samples in the order that prevent cross-contamination of sample tube additives. As described above for adult patients, collect the capillary haematology specimen first, followed by the chemistry and blood bank specimens.How do you label a capillary tube?

Why is the order of draw different for a capillary puncture from a venipuncture collection?
The order of draw for a capillary blood collection is slightly different than the order of draw for a venous blood collection. … This is to ensure that the blood will not begin to clot before this specimen is collected; clots will affect the accuracy of the blood count.

What is the first step in performing a capillary stick?
Hold the finger in an upward position and lance the palm-side surface of the finger with proper-size lancet (adult/child). Press firmly on the finger when making the puncture. Doing so will help you to obtain the amount of blood you need. Cap the Microtainer® and gently invert it 10 times to prevent clots from forming.
What is a rainbow lab draw?The practice of collecting extra blood tubes at the time of initial phlebotomy, often referred to as a “rainbow draw” (because of the various colors of tube stoppers) is a common but controversial procedure in many emergency departments (EDs)3.
Article first time published onWhy is the order of draw important?
The order of draw is recommended for both glass and plastic venous collections tubes when drawing multiple specimens for medical laboratory testing during a single venipuncture. The purpose is to avoid possible test result error due to additive carryover.
What is in the capillary tube?
Capillary tubing or capillary tubes are very thin tubes made of a rigid material, such as plastic or glass in which a liquid flows up into the tubes against gravity in a process called capillary action (capillarity). … A fluid’s capillary action can occur in both vertical and horizontal directions.
How do you fill a capillary tube?
Hold the Capillary Tube at an angle of 10 degrees below the collection site and touch the tapered end of the tube into the droplet of blood. Do not touch the skin with the tube. Fill to the 50 µL black line. Filling stops when the sample reaches the black line.
How do you remember Order of phlebotomy?
Some phlebotomist use a mnemonic to help them remember. Blog Market Lab shared some very humorous mnemonics, such as “Studious Boy’s Rarely Get Low Grades” referring to Sterile, Blue, Green, Lavender and Grey.
Why is the order of draw important in phlebotomy?
Blood samples must be drawn by phlebotomists in a specific order to avoid cross-contamination of the sample by additives found in different collection tubes. Phlebotomy order of draw is the same for specimens collected by syringe, tube holder, or into tubes preevacuated at the time of collection.
Does order of draw matter?
In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. … Modern lab equipment can tell the difference between K from the EDTA tube and K from the patient, so order of draw is no longer important.
What order do you draw blood cultures?
When drawing multiple blood samples from a line, always draw the blood culture first. Do not discard any blood from the line. Use this initial blood in the line, as this may be the best source if an organism is present.

- four. compare patient information with requisition ( if patient, compare with armband)
- five. sanitize hands and put on gloves.
- six. position patient.
- seven. …
- eight.
Which are the following tubes are used for capillary sticks?
Capillary punctures require different devices than the typical venipuncture equipment. They include lancets, microcontainer tubes, microhematocrit tubes and sealants, and warming devices.
How many labs can one tube draw?
ALL OF THIS PAGE CAN SHARE A TUBE UP TO ABOUT 12 TESTS.
What is a lithium heparin tube?
VACUETTE® LH lithium heparin tubes are coated with lithium heparin on the inside. The anticoagulant heparin activates antithrombin, which blocks the clotting cascade and thus produces a whole blood/plasma sample. Selected tubes are also available with a transparent label.
What is a rainbow in phlebotomy?
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 does rainbow extra tube mean?
There is a perception that ED patients will typically require additional or follow-up testing, so drawing these extra tubes prevents the need for a second blood draw. … Thus, when laboratory phlebotomists receive an order for testing, they end up drawing a rainbow of extra colored tubes during the initial blood draw.
What are the 3 most common veins used in phlebotomy?
The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).
What is a capillary puncture quizlet?
Also known as dermal puncture, capillary puncture is a quick, safe, and efficient means of collecting a blood specimen. … Capillary punctures are only performed when a small amount of blood is required such as obtaining blood from infants or when the patient has a condition that makes venipuncture difficult.
What is capillary tube Class 11?
Hint: Tubes with small diameters are known as capillary. These tubes will show rise or fall of liquid when it dipped in a liquid. This is known as capillarity and it will occur due to the cohesive force between the molecules of liquid and adhesive force between the surface of the tube and the liquid.
What is capillary tube in thermometer?
CTT-01: A capillary tube is used in the thermometer to indicate the temperature scale. … When the temperature changes, the measuring liquid column moves up and down within the capillary hole. Usually the scale of the thermometer is located on the capillary tube.
How do you calculate capillary tube size?
From Table A-1, we find 8 ft length of 0.064 in capillary tube. Example: to convert 11 ft of 0.031” capillary to 0.028”, multiply length by 0.56, i.e., 11 ft * 0.56 = 6 ft. As a result, 6 ft of 0.028” capillary has approximately the same capacity as 11 ft of 0.031” capillary.
