What color tube is used for the CBC test?

CBC test(Hemolysis)

Hemolysis can be caused by rough handling of a blood sample, by allowing the tourniquet to run too long (causing blood congestion), or by squeezing the fingertip too much during capillary collection, dilution, exposure to contaminants, extreme temperatures, or pathological conditions. To ensure accurate test results, all tubes containing an anticoagulant or preservative must be completely filled. This results in a shift of fluid between the vein and surrounding tissue. Specific requirements can be found in the individual test directories.

Which color tube is used for the CBC test?

Since additives are not interchangeable, it is necessary to consult the sample requirements section of the individual test descriptions to determine the appropriate collection requirements for the ordered test. As hemolysis affects many procedures, please submit samples that are as free of hemolysis as possible. Do not use gel barrier tubes to submit samples for therapeutic drug monitoring, direct Coombs, blood type, and blood groups. Always use the correct vacuum tube for tests that require a specific anticoagulant (such as EDTA, heparin, sodium citrate, etc.) or preservative.

Plasma is obtained from blood that has been mixed with an anticoagulant in a collection tube and is therefore not coagulated.

After experiencing a variety of shortages, crises, and inefficiencies in the status quo of the procurement and distribution industry, I undertook the responsibility of building an interface for large organizations to abstract away uncertainty throughout their supply chain under most conditions.

We are focused on building a framework from which our teams of professionals on the ground can provide a new generation of procurement support and professional services for supply chain critical organizations around the nation.

We understand that the marketing process of critical supplies is a matter of national security and public safety. In this, we found our passion and mission: developing technologies, supplier networks, and platforms for the organizations that need it most.
