Blood Collection Tube–Plain Tube–No Additive Tube
Short Description:
The red cap is called ordinary serum tube, and the blood collection vessel does not contain any additives. It is used for routine serum biochemistry, blood bank and serological related tests.
Venipuncture
In medicine,venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of venous blood sampling(also called phlebotomy) or intravenoustherapy.Inhealthcare---this procedure is performed by medical laboratory scientists,medical practitioners,some EMTs,paramedics,phlebotomists,dialysis technicians,and other nursing staff.In veterinarymedicine,the procedure is performed by veterinarians and veterinary technicians.
It is essential to follow a standard procedure for the collection of blood specimens to get accurate laboratory results.Any error in collecting the blood or filling the test tubes may lead toerroneous laboratory results.|
Venipuncture is one of the most routinely performed invasive procedures and is carried out for any of five reasons:
1. Obtain blood for diagnostic purposes;
2. Monitor the level of blood components;
3. Carry out therapeutic treatment, including drugs, nutrition or chemotherapy;
4. Remove blood due to high levels of iron or red blood cells (red blood cells);
5. Collect blood for later use, mainly in the donor or other human blood transfusion.
Blood analysis is an important diagnostic tool available to clinicians within healthcare.Blood is most commonly obtained from the superficial veins of the upper limb.
The median cubitalvein,which lies within the cubital fossa anterior to the elbow,is close to the surface of the skin without many large nerves positioned nearby.Other veins that can be used in the cubital fossa forvenipuncture include the cephalic,basilic,and median antebrachial veins.
Minute quantities of blood may be taken by fingerstick sampling and collected from infants by means of a heelprick or from scalp veins with a winged infusion needle.
Phlebotomy(incision into a vein)is also the treatment of certain diseases such as hemochromatosis and primary and secondary polycythemia.
