A Guide to Purple Top Tubes for Blood Collection

When it comes to blood theme, and diagnostic analysis, purple top tubes in the medical fraternity have their special significance. Below, are some of the vacuum tubes that are coated with EDTA (Ethylenediaminetetraacetic acid), which go a long way in enhancing the working of healthcare institutions. It is important to be aware of what makes these tubes necessary, some of the uses to which they may be put and how best to employ them.

What are Purple Top Tubes?

Lavender top tubes commonly known as purple top tubes for blood collection are meant for containing blood samples that will undergo disparate tests. EDTA the primary reagent in these tubes is an amino polycarboxylic acid that acts as a chelating agent. Yet it forms a complex with calcium ions in the bloodstream which makes it unable to cause coagulation. Due to its ability to chelate calcium, EDTA has a very useful function of preventing blood samples from clotting and thus can be used alongside laboratory exams.

The Science Behind EDTA

And once again, because EDTA is capable of binding with and chelating calcium, it makes a good coagulant. When compared with other anticoagulants, there may be a stronger influence on tendencies towards blood cell aggregation and morphology with EDTA but this is outweighed. This makes it especially valuable for:

•          Clinical hematology

•          Cross-matching

•          Blood grouping

•          Various blood cell tests

However, EDTA tubes may not be applicable for all tests to be run mainly because the anticoagulant affects the parameters being investigated. They are excluded from any process in which the accurate measurement of blood coagulation is important or in trace element testing, PCR assays.

The Features of Purple Top Tubes Used for Blood Collection

It is necessary to comprehend the necessary characteristics of the purple top tubes for blood collection while choosing the necessary product. These tubes are available in two primary materials: glass and PET (polyethylene terephthalate), flexible according to the lab’s requirements. Available dimensions are 13mm x 75mm, 13mm x 100mm, and 16mm x 100mm, to meet different volume needs.

• Thus, the tubes are available in purple color to show compatibility with EDTA K2 or EDTA K3 additives which do not cause coagulation. They are meant for collecting blood volume of between 1ml and 10ml hence can be used in different tests. Assembled in Shijiazhuang, Hebei, China they are available in CE & ISO 13485 standard quality tubes that ensure quality.
• This means that OEM copies can be made to fit any design requirement a user may have and is also possible to provide free samples. Styling With packaging, tubes can be 100 per tray/tray pack, which can be arranged in cartons of 1200 or 1800 tubes depending on the convenience of packaging and transportation. Tianjin or Shanghai ports for shipping are always available, and the items will be delivered to your place as soon as possible.

Usage of Purple Top Tubes

To ensure the integrity of your blood samples, follow these steps when using purple top tubes:

Check Instructions: He or she should always check the label and certification that come along with the packing of the product.

Inspect Tubes: Ensure that the tubes are not damaged and they are not contaminated.

Assess Volume: Ensure the correct volume of blood for testing purposes is the correct one.

Perform a Blood Draw: Penetrate the skin with the end of the blood needle and then transfer the other part of the blood needle to the collection tube if blood starts to flow.

Invert the Tube: Once the needle has been withdrawn – rotate the tube in a figures-eight fashion five to six times.

The Benefits of Using Purple Top Tubes

The design and manufacturing process of purple top tubes for blood collection ensure they perform reliably:

•          Uniform Additive Distribution: Sophisticated methods are used to apply the supplied EDTA additive over the inner part of the tube, thus ensuring it mixes well with the blood sample.

•          Preservation of Blood Cells: These tubes afford satisfactory protection of cells with special reference to platelets with respect to shape and size.

•          Versatile Applications: EDTA anticoagulant plasma can be used for the following biological tests agglutination tests for pathogenic microorganisms and their components, inhibitory substances against mast cells, and substances affecting respiration.

•          Accurate Testing: Due to its anticoagulant properties, purple top tubes enable correct blood testing and, consequently, provide accurate outcomes.

•          Prevent Clotting: These tubes inhibit clotting of blood ensuring that the resulting sample is ready for the test, which is very important in haematological examination.

•          Improved Patient Care: Such blood tests lead to better decisions by healthcare givers and, in turn, benefit the patient.

Where are Purple Top Tubes Used?

Purple top tubes for blood collection are important for different types of practices since they are used to determine the correct amount of blood to sample as well as being utilized for diagnostics. Here’s a closer look at their primary applications:

Hospitals

For common culture and forensic chemistry needs, blood vessels are employed whereas purple top tubes are used both in emergency situations and more general blood analysis. Promising to minimize coagulation they guarantee accurate results and that is crucial for a patient’s treatment.

Clinics

These tubes serve clinics to perform instantaneous health evaluation; through blood samples tested in the tubes, competent decisions on patient care can be made immediately.

Medical Laboratories

Purple top tubes have therefore become important in medical laboratories since they are used for multiple testing and analytical procedures. Through the use of the EDTA additive, the blood samples remain flawless and appropriate for hematological tests.

Diagnostic Centers

In centers that deal with the diagnosis of various diseases, purple top tubes are important because some tests need well-coagulated blood or a steady clot in order to give the right diagnosis for complicated diseases.

Research Institutions

In addition, purple top tubes are used in research-driven institutions where precise blood sample differentiation is indispensable in assisting medical research in their overall research and management of different diseases.

Why Choose Purple Top Tubes?

It has shown that the decision to use purple top tubes is in a position to affect the results of the blood tests. It is important for the diagnosis and treatment that samples do not coagulate, and thanks to their properties, this does not happen. Moreover, because EDTA is a very diverse anticoagulant, these tubes are suitable for almost all hematological examinations.

Conclusion

Purple top tubes for blood collection are indispensable tools in modern healthcare. Their ability to prevent blood clotting while preserving cell morphology makes them a favorite among medical professionals. By understanding how to use these tubes effectively, you can contribute to accurate diagnostics and improved patient care.
