In the tubing which will result in a short draw in the light blue stopper tube.

. Collect citrate tube blue top last after 20mL of blood has been withdrawn for other testing or as waste. Draw blood into a plastic blue top tube which contains 32 0109 M sodium citrate anticoagulant. Uncentrifuged or centrifuged in an unopened tube kept at 18-24C must be tested within 24 hours from the time of specimen collection.

Mixing ratio is one part citrate to nine parts blood when tube is filled appropriately as indicated by fill mark on label. 13 75mm tubes filled with buffered tri-sodium citrate solution. 2 eliminating breakage when tubes are centrifuged at higher speeds.

Underfilled Coagulation Tubes. A specimen of blood in a 32 sodium citrate 50 mL tube was drawn from one arm with a discard tube and from the other arm without a discard. Minimum fill indicator represents the minimum volume of blood required for appropriate analysis.

If testing is not completed within 24 hours plasma should be removed from the cells and frozen at -20C for up to two weeks. Theres no need to waste your precious supply of blue tops on frivolous usage like drawing rainbows and using citrates for discard tubes. Citrate BD Vacutainer Citrate Tubes with 32 buffered sodium citrate solution are used for routine coagulation studies.

Sodium Citrate either 32 or 38 Citrate theophylline adenosine. Citrate is used as an anticoagulant for clotting tests because it. To accurately fill the Light Blue Top Tube with the correct amount of blood fully seat and hold the Light Blue Top Tube against the back.

32 0109 molL concentration. Evacuated BCTs are generally cylindrical measuring 50 mm to 150 mm in length and 10 mm to 20 mm in diameter Most tubes for adult clinical specimens are 75 mm to 100 mm in length and 13 mm in diameter and collect 2 to 10 mL of whole blood 910Micro-collection tubes for pediatric specimens are 40 to 50 mm in length and 5 to 10. Closure Reference Tube Size Draw Volume mm mL Type Colour Label type 366392 G 1025x47 18 P 366393 G 1025x64 27 P 363080 13x75 18 P 363083 13x75 27 P 366415 G 13x75 45 P 367599 G 13x75 45 P.

The simple answer to your question is that since perhaps no one used expired BD 32 sodium citrated tubes to measure fibrinogen no body knows. And 3 eliminating breakage or chipping of tube rims when stopper is removed and reinserted. Centrifuge the citrated blue-top tubes as soon as possible within 60 minutes at designated time and speed to obtain platelet-poor plasma 10000µLUsing a plastic pipette remove 1 mL of plasma and transfer to a plastic polypropylene aliquot tube and label with patients name and a second patient identifier eg date of birth medical record number.

Prolonged APTT and prolonged PT b. A short draw with a sodium citrate tube will lead to a prolonged aPTT and prolonged PT Which of the following anticoagulants prevents coagulation of the blood by removing calcium through the formation of insoluble calcium salts. A short draw yields grossly inaccurate results.

Light Blue Top Tube Sodium Citrate Use for Prothrombin Time or PT Immediately prior to drawing the Light Blue Top Tube clear the air out of the access tubing by partially filling a RedGray Stopper Top Discard Tube and then discard. Most tubes contain contain 03 mL anticoagulant and draw 27 mL of blood. This effect is most pronounced in samples drawn into 38.

A short draw with a sodium citrate tube will lead to. When coagulation tests are performed in the laboratory calcium is added to allow clot formation. 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.

Underfilling may significantly affect the APTT and PT resulting in artifactual prolongation of results. Standard evacuated tubes 32 and 38 sodium citrate were filled to varying total sample volumes ranging from 30 to 50 mL and results of routine coagulation tests were compared. Most studies on 32 sodium citrate evacuated tube fill volumes helped establish the 90 rule and also confirm that 32 citrate is more forgiving than 38 largely discontinued in 2001.

Full Blue-top sodium citrate tube 18mL- Hemolyzed or short draw specimen is not acceptable. Shortened APTT and shortened PT c. With 32 buffered sodium citrate solution Provide a safer work environment for all personnel by 1 reducing risk of tube breakage during handling.

Impact of evacuated tube fill volume and mixing on routine coagulation measures using 25 mL pediatric tubes. Testing that uses these sodium citrate blood specimen light blue top collection tubes is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of. Allow the tube to fill to the proper level determined by the vacuum in the tube.

Order of draw Colour coding Tube type Recommended inversions Minimum clotting time Centrifuging conditions Disposable tubes EST or other suitable tube not necessary na na Blood culture Anaerobic blood culture bottle na na na Aerobic blood culture bottle na na na Citrate Sodium citrate plastic 3-4 na 2000-2500 g RCF for 10-15 min. Coagulation tubes blue top are filled with a solution of sodium citrate which acts as an anticoagulant by chelating calcium. A discard tube without additives must be used if only a citrate tube is to be drawn using a winged blood collection.

Tubes should fill between 10 of the stated draw volume of the tube CLSI guideline Dec. The purpose of this study was to compare results obtained for the prothrombin time PT and the activated partial thromboplastin time APTT using specimens drawn with and without a discard tube in healthy adults. Being wise stewards of your resources means planning for shortages like the one happening right now.
