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 is the proper order of the draw?
The correct order of draw follows: Blood culture tube or bottle. Sodium citrate tube (eg, blue closure) Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)
What is the order of draw phlebotomy?
The recommended order of draw for plastic collection tubes is: First – blood culture bottle or tube (yellow or yellow-black top)Second – coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn.When filling tubes with blood samples which type is filled first?
The sequential order of draw is to help prevent additive carryover from one tube to the next. Order of Draw for capillary collection (finger/heel): lavender, green, gray, red/yellow. Mix lavender, green, gray at least 10 times. Capillary collection tends to form clots quickly, so tubes w additives are collected first.
Which tubes to draw for labs?
- Blood Culture Tubes or Vials.
- Coagulation Tubes (Blue-Top Tubes)
- Serum Tubes without Clot Activator or Gel (Red-Top tubes)
- Serum Tubes with Clot Activator or Gel (Gold or Tiger Top Tubes)
- Heparin Tubes (Green-Top Tubes)
- EDTA Tubes (Lavender-Top Tubes)

Why should you follow the correct order of draw during phlebotomy?
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.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.
Why is the order of draw important?The order of draw is necessary to obtain correct biochemical results. EDTA contamination was not evident in blood samples collected by trained phlebotomists. The biochemical alterations are statistically and clinically significant.
Article first time published onWhat is the order of draw for dermal puncture?
recommended order of draw is blood cultures, sodium citrate tubes, serum tubes with or without. clot activator, with or without gel, heparin and heparin gel tubes, EDTA tubes and then fluoride. tubes.
Do you centrifuge red top tubes?
Red top tubes contain no additives. Red top tubes must be allowed to clot completely (30-60 minutes) prior to centrifugation. Centrifuging the specimen yields serum. NOTE: All drug levels must be drawn in red top tubes only.
Which of the following are included in steps for collection of a blood specimen?
Blood collection methods include (1) venipuncture (penetrating a vein with a needle) with an evacuated tube system, syringe method, or butterfly infusion set; and (2) capillary blood system whereby the skin puncture is done with the use of a lancet.
How many labs can one tube draw?
ALL OF THIS PAGE CAN SHARE A TUBE UP TO ABOUT 12 TESTS.
Which tube is used for electrolyte testing?
Specimen Requirements Gel-barrier tube (send entire tube) preferred. Red-top tube or green-top (heparin) tube is acceptable if centrifuged within 45 minutes and the serum or plasma is removed and placed in a tightly-stoppered secondary tube.
What is the single most important step of blood collection procedure?
Venipuncture is the process of collecting or “draw- ing” blood from a vein and the most common way to collect blood specimens for laboratory testing. It is the most frequent procedure performed by a phle- botomist and the most important step in this proce- dure is patient identification.
What is the first step in routine blood collection?
The first step to the collection is to positively identify the patient by two forms of identification; ask the patient to state and spell his/her name and give you his/her birth date.
How is phlebotomy performed?
Phlebotomy is when someone uses a needle to take blood from a vein, usually in your arm. Also called a blood draw or venipuncture, it’s an important tool for diagnosing many medical conditions. Usually the blood is sent to a laboratory for testing.
How do you label a capillary tube?
Included on the label should be at least the first and last name of the patient, the medical record or identification number, the date and time of collection, initials of the person collecting the specimen, and any other information required by the collecting facility.
Is the order of the draw the same for capillary draws as it is for venipuncture specimens?
The order of draw for a capillary blood collection is slightly different than the order of draw for a venous blood collection. If capillary blood gases are ordered, they are drawn first to avoid introduction of room air as much as possible.
How do you process a SST tube?
To obtain serum, whole blood should be collected into either an SST or plain red top tube. After collection, allow the tube to sit in an upright position at room temperature for 30-45 minutes. After the clot has formed, centrifuge the tube for 10 minutes at 3400 rpm.
How do you process a red top tube?
- Draw whole blood in an amount 2½ times the required volume of serum so that a sufficient amount of serum can be obtained. …
- Place the collection tube in the upright position in the rack, and allow the blood to clot at room temperature for 30 to 60 minutes.
Do you centrifuge EDTA tubes?
Plasma preparation Collect whole blood into commercially available anticoagulant-treated tubes e.g., EDTA-treated (lavender tops) or citrate-treated (light blue tops). … Cells are removed from plasma by centrifugation for 10 minutes at 1,000–2,000 x g using a refrigerated centrifuge.
