Vacuum Blood Collection Tubes

What is?

VacuSEL Vacuum Blood Collection Tubes are PET tubes that are resistant to breakage and subjected to vacuuming at the vacuum value calculated to take a predetermined amount of sample exactly at the desired volume.

Caps produced with color codes determined by international standards are used in the production of our vacuum blood collection tubes. These covers are designed to prevent spillage of the collected samples by opening them suddenly, and blood splattering during the sampling or during the opening of the cover.

The plug of the cover is of a special structure that allows easy sampling with the needle and analyzer probe and does not damage the equipment used. Thus, it is possible to work with samples quickly and safely without opening the tube cover.

The additives used in our vacuum blood collection tubes, their concentration and blood-additive ratios are determined by international standards and comply with the permitted requirement sand recommendations.

What does it do?

VacuSEL Vacuum Blood Collection Tubes are used for blood collection, blood transfusion, blood storage or blood processing to test serum, plasma or whole blood in the clinical laboratory and are for professional use.

When a blood test is requested in laboratories, blood is taken into tubes of different colors and characteristics. The inspection device and method of each test differs. While some of the tubes may contain anticoagulant that prevent coagulation or provide plasma separation, some have additive-free tubes to obtain serum or tubes with activators to accelerate this process.

The usage areas of the Vacuum Blood Collection Tubes are as follows, according to their colors.

With EDTA tubes(PURPLE); Hemogram, Reticulocyte, Formula leukocyte, Blood Group, Cross-match, Direct Coombs, Indirect Coombs tests are performed.

With citrate tubes (BLUE); PT, aPTT, Fibrinogen, D-Dimer, Coagulation Factors (FII, FV, FVII, FVIII, FIX, FX, FXI, FXII, FXIII), Collagen-ADP, Collagen-Epinephrine, Protein C, Protein S, ATIII, TT, Lupus Anticoagulant, VWF:Ag and VWF:RiCoF, Antifactor Xa are studied.

Sedimentation test works with black capped (Citrated) tubes.

Serum tubes (Yellow-Red); are used for many tests such as Biochemistry-Hormone-Microbiology-Serology-Immunology-Blood Bank.

Heparin (Green) tubes; are used for other analysis and biochemistry analysis requiring NT-ProBNP and Plasma. Sodium heparin is used for the lithium level. Sodium or lithium heparin is used for the ammonia level.

Glucose Tubes (Gray); are used in the long-term storage of some substances such as glucose measurement and ethanol. Antiglycolytic agents retain glucose for up to 5 days.

Vacuum Blood Collection System

In the past, before vacuum blood collections systems were used, it was much more difficult to collect blood samples and come to definitive conclusions with these collected samples. More time, effort and money were spent for making a diagnosis.

The needles used to draw blood from the vein and the tubes used to collect the blood sample were not disposable. The tubes were made of borosilicate glass so that they could be reused. Although they were resistant to impacts, they were broken as a result of accidents from time to time, causing people to be injured. Needles were ground to sharpen before being used in another patient, glass tubes were washed and then both were sterilized.

Although the products were sterilized, sterilization in hospital and laboratory environment increased the risk. Glass tubes had notches engraved on the tube to facilitate blood collection. In addition, in order to prevent blood clotting, EDTA or Sodium Citrate solution prepared by the laboratory officers were placed in certain volumes into the tubes before blood collection. Samples were usually sealed with black rubber stoppers before being transported to the laboratory.

All these processes increased the probability of error due to the human factor. For this reason, the accuracy of the results obtained was decreasing. In order to minimize the accidents that may occur in glass tubes and speed up the diagnosis process, break-resistant and disposable PET tubes were later used. Later, vacuumed pet tubes were started to be used to prevent errors in the blood-additive ratio.

Today, a system consisting of a vacuum blood collection tube, needle tip or butterfly needle and holder is used to collect venous blood. This system increases the accuracy of the test and the diagnosis to be made by minimizing the errors that may occur with the human factor, ensuring that the blood sample is taken easily, safely, in desired volumes and mixing at the correct blood-additive ratio.

Apart from these, any product, apparatus or method to be used will go out of this system and render the system ineffective. For example; taking blood with the syringe and injecting the blood with or without opening the cap of the tube may disrupt the structure of the blood and this may cause erroneous results. It may lead to over or under specimen collection. This will prevent the vacuum blood collection system from fulfilling its mission.
