which one of the following tube types is used to collect blood for platelet function studies?
308871
Most instruments used for platelet function testing require the use of citrated blood. Blood is collected by venipuncture into a plastic tube containing buffered 3.2% sodium citrate, which is then mixed gently immediately upon filling.

The principal function of platelets is to prevent bleeding. Red blood cells are the most numerous blood cell, about 5,000,000 per microliter. Red blood cells make up about 40% of our total blood volume, a measure called the hematocrit.

Volumetric pipettes, also known as bulb pipettes, are manual liquid handling devices used in many laboratories for the transfer and dispense of a single, specific quantity of liquid to a very high degree of accuracy.

Stopcocks between the collection chamber and drainage bag allow control of the entry of CSF and its drainage (Fig 3). The collection chamber and pressure scale hang side by side. Pressure is measured in millimetres of water pressure (cmH20).

Why are EDTA specimens obtained before other specimens when collected by skin puncture? To minimize effects of platelet clumping.

Where are SPS (sodium polyanethol sulfonate) tubes used? A. SPS tubes are used for blood culture specimen collection in microbiology. Eight gentle tube inversions will prevent the blood from clotting.

This tube is a plain glass Vacutainer® containing no clot activators, anticoagulants, preservatives or separator material. These tubes can be used for Blood Bank tests.

Packed red blood cells (PRBCs) are made from a unit of whole blood by centrifugation and removal of most of the plasma, leaving a unit with a hematocrit of about 60%. One PRBC unit will raise the hematocrit of a standard adult patient by 3% (or about 1%/mL/kg in a child - 12%/25 kg with the standard 300 mL PRBC unit).

Automated Red Cell Donation (Alyx) In this type of donation, you give just red blood cells while your platelets and plasma are returned to you. The procedure uses a smaller needle, and collects enough red blood cells to be transfused to two different patients.

If blood is drawn into a tube without anticoagulant: plain red or SST, then the blood will clot naturally and separate into liquid and cells. This liquid is called serum. ... This liquid is called plasma. It is the liquid portion of blood when the tube contains anticoagulants.

Blood transfusion can be performed using a combination of red blood cells, platelets, and plasma. Total volume for each unit is around one pint, in a range of 450 ml to 525 ml.

Platelet Donation A single donation of platelets can yield several transfusable units, whereas it takes about five whole blood donations to make up a single transfusable unit of platelets. Platelets are collected at Red Cross donation centers only, and are not collected at blood drives.

Apheresis platelets are usually called single donor platelets because they are collected from a single donor with an automated cell separator. Donors usually have an IV line in each arm. ... Single donor platelets offer several advantages over random donor concentrates including: Less inventory and pooling.

These are classified as blood components prepared in the blood transfusion centre (red cells, platelets, fresh frozen plasma and cryoprecipitate) or plasma derivatives manufactured from pooled plasma donations in plasma fractionation centres (such as albumin, coagulation factors and immunoglobulins).

Random Donor platelets (RDP) are prepared from donated blood with in 4 to 6 hrs of collection by centrifugation & it contains approximately 5.5 x 1010 platelets. Single Donor Platelets (SDP) are prepared by platelet aphaeresis machine. One unit of SDP is equivalent to 5 to 10 units of RDP.
