NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.To avoid RBC shrinkage due to excess EDTA (with resulting changes in HCT and RBC indices values) and possible dilutional effect, the tubes should be filled with the proper amount of blood for the size of tube used. You must draw some blood into a "discard" tube first. The purpose of the citrate is to remove calcium ions that are essential for blood coagulation; however, failure to fill the draw tube adequately causes the final citrate concentration of the patient sample to be too high.

A thrombus is a Gel-barrier tubes and serum tubes … Tube … Methods: Multiple blood samples for coagulation testing were obtained from study subjects in full-draw pediatric collection tubes made of siliconized glass. A discard tube is not required prior to collection of coagulation samples except when using a winged blood collection device (i.e. Collection, Transport, and Processing of Blood Specimens for Testing Plasma-Based Coagulation Assays and Molecular Hemostasis Assays; Approved Guideline—Fifth edition. Top Answer. Heparin tube - green top. Emulsify several isolated colonies of test organism in 1 ml of diluted rabbit plasma* to give a milky suspension. See Answer. Coagulation tubes are mainly used for examination of coagulation parameters and can provide an excellent condition for the test of PT, APTT VALUES. How to perform a PT test using the KC1 semi-automated coagulation analyzer. Oxalate/fluoride tube- gray top. Laboratory Testing. Must arrive in lab within 1 hour of collection. Coagulation tests measure your blood’s ability to clot and how long it takes. This is especially true for specimens which are being frozen for any kind of Lupus Anticoagulant testing. Do not shake. Specimen Collection Collect specimen in blue top (3.2% sodium citrate) tube. 4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes.

VacuLab® Coagulation tubes are filled with a buffered sodium citrate solution. CTAD for selected platelet function assays and routine coagulation determination. These tubes contain pre -measured vacuum and pre-measured additives; therefore it is very important that these tubes are filled to the “stated fill” volume. If you under-fill or over-fill your collection tube, there is the potential for incorrect analytical results being reported. Which tubes must be completely filled with blood?
