what is blood products ?
Blood products are therapeutic substances prepared from human blood. keep reading with me in this article to know more about blood products.
The blood contains different components, including red blood cells ( RBCs ), white blood cells ( WBCs ), platelet and plasma. Plasma contains antibodies (immunoglobulins) and clotting agents.
Not all components of a particular unit of donated blood are produced or prepared; for example, immunoglobulins and clotting agents can be prepared from plasma combined from numbers of donors. WBCs and blood platelets is made through blood bleeding depending on the condition, the disease may only receive red blood cells, blood platelets, plasma, or clotting factors only.

The transfer of selected blood components only allows treatment to be specific or qualitative, reduces the risk of side effects and different components can be used efficiently from one unit of blood for treatment of multiple patients.
Sometimes,blood products are treated with radiation to reduce the risk of attacking the recipient’s transmitted WBCs.
Red blood cells
Stacked red blood cells, the most transmitted blood component, can increase the ability to carry oxygen in the blood. This ingredient can also be given to a bleeding person or who has severe anemia. The erythematosus is separated from the liquid component of the blood (plasma) and other cellular components. This step focuses on the red blood cells so that they occupy less space, hence the term “stacked or stacked”.

Sometimes, red blood cells are specially prepared ( washed RBCs ), so that they can be given to people who have severe reactions to plasma. Washed red blood cells are free of all plasma traces, most white blood cells, and blood platelets. Special filters are routinely used to remove WBCs, with the aim of reducing a number of side effects, including fever, chills, cell-amplified virus infection and creation of antibodies to human WBCs antibodies (HLA). HLA antigens are chemical poisons that are placed on the surface of cells and are unique in every organism so the body can distinguish itself from others.
Red blood cells can be cooled for up to 42 days. In special cases for example to maintain a rare type of blood. red blood cells can be frozen for up to 10 years.
Blood platelets are small cell-like particles in the blood that help form clots. Blood platelets are usually given to people with severe hypothaepromism (low platelets – thrombocytopenia), which can lead to severe and spontaneous bleeding. Blood platelets can be stored for only 5 days.
In the past, several donors were needed to provide enough blood sheets for one person, but modern combination techniques, which separate blood platelets better from other blood components, allow one donor to provide enough blood filters for one person’s needs.
Plasma, the liquid component of blood, contains a number of proteins, including blood clotting agents. Plasma is usually frozen after separation from fresh blood (fresh frozen plasma). Frozen plasma can be stored within 24 hours of collection for up to a year. They are used in bleeding disorders where the missing clotting factor is unknown, or when the specific clotting factor is not available. Plasma is also used when bleeding occurs due to inadequate production of all or a number of different clotting factors as a result of liver failure or severe infection.
Blood clotting factors
Blood clotting factors are proteins found in blood plasma, which usually work with blood vessels to help blood clots. Without these clotting factors, bleeding will not stop after injuries and bruises. Some concentrated clotting factors are called plasma cryoprecipitate.
The suppositial sedimentary hormones are often given to people who have severe bleeding with very little fibrinogen, it’s an important clotting factor (for example, in patients with intravascular clot or placental detachment). Cotsallic proteins can also be individually purified from assembled plasma, or manufactured using genetic sequencing methods. Concentrated blood clotting factors can be given to people with an inherited bleeding disorder, such as amyloidosis or von Willebrand’s disease, and to remove the effects of blood clotting medications (anticoagulants, such as warfarin).
Antibodies (immunoglobulins), blood-fighting components, are sometimes given to provide temporary immunity to people who have had contagious diseases or have low levels of antibodies. Antibody infections include chickenpox ( follies), hepatitis, rabies and tetanus. Antibodies are produced from the donor treated plasma from several donors.
White blood cells (WBCs)
WBCs are transported to treat life-threatening infections in people who have a significant decrease in the number of white blood cells, or whose WBCs do not work normally. The transfer of WBCs is rare, due to improved antibiotics and the use of cytokine growth factors that stimulate the production of more WBCs for patients, greatly reducing the need for such blood transfusions. Get WBCs by blood bleeding and you can store for up to 24 hours.
Researchers have tried to create blood substitutes that use certain chemicals or solutions specifically treated for hemoglobin (a protein that allows red blood cells to carry oxygen), with the aim of transporting oxygen to and supplying oxygen to tissues. These solutions can be stored at room temperature (often for several years – much longer than keeping blood in blood banks), and you don’t need to identify their clique or match the people who receive them. These characteristics make them worthy of relocation to the site of casualties or to the battlefield. However, studies have not shown that any of these alternatives have so far saved lives. Doctors are doing more research on other possible blood replacements.
Now dear readers, having learned the answers to your questions about blood products. Thank you for reading this article and you can know more about blood from his website.
