Quiz 8 :
Blood Collection Equipment

The people suffering from thrombotic disorder require anticoagulants. Anticoagulants refer to the types of drugs that are responsible for prevention of blood clotting. It can also prolong the time of clotting of blood. They are also used in the medical equipments, such as blood transfusion bags and test tubes. The tubes used for collection of blood are considered as the blood collection tubes. They are available in different shapes and sizes. In the clinical laboratory, assays are performed with the help of plasma, serum or whole blood. The anticoagulants, such as ammonium and sodium heparin are found in green-topped tubes. They are used to perform tests on platelets as well as whole blood. The whole blood can be used for testing of total time taken for blood clotting.

The tubes used for collection of blood are considered as the blood collection tubes. They are available in different shapes and sizes. In the clinical laboratory, assays are performed with the help of plasma, serum or whole blood. Ammonium oxalate, sodium citrate and sodium heparin are not found in the white-topped vacuum tube. Hence, the options b, c and d are incorrect. EDTA (Ethylenediamine tetra-acetic acid) is responsible for preventing the aggregation of blood platelets. Therefore, it can be used in the test that involves platelets counts. It also responsible for preparation of the blood films with very less distortion of white blood cells (WBC). It is found in the white capped vacuum tubes. Hence, the correct answer is option img .

The device that is used to puncture skin and collect blood is considered as the needles, lancets and syringes. They come in different sizes. The patients are too fragile for collection of blood through vacuum tubes. Therefore, syringes are used for collection of blood. There is an increased risk of needle-stick while using syringes and needles. The skin puncture procedure of blood collection is used in adults as well as infants to collect blood that can be further used to diagnostic procedures. In this procedure, very less amount of blood should be collected. The diameter is inversely proportional to the gauge. This means that with increase in gauge that diameter of the needle decreases. The needles with gauge 17 and 18 are used for blood donation.
