Red cells are seperated from a blood donation for their use in hemophillic patients
it is when two particles of blood are stuck together and are donated in a facilitie.
Per the blood bank you have to wait 16 weeks, or double the normal time for a single red blood cell donation. Normal wait time for red cell donation is only once every 8 weeks and since this procedure draws what amounts to two donations in one, your wait time is double.
Increaed fluid intake immediately before and after a double red cell donation will help prevent most post-donation vaso-vagal reactions. A simple one-a-day vitamin with iron will help restore hemoglobin/hematocrit to acceptable levels within 3-4 weeks, and prevent iron deficiency following frequent red cell donations.
Current FDA guidelines allow a maximum of 10.5 ml/kilogram body weight of whole blood to be collected every eight weeks. The majority of blood collection facilities use 500 ml whole blood bags, with an additional 50 ml (10%) allowed to be drawn for mandated screening tests. This volume equates with a lower body weight for blood donation of 110 lbs or more (with acceptable hematocrit/hemoglobin levels). Double red cell donation by apheresis technology may collect 500-550 ml of red cells at a single donation IF the donor meets body mass and hematocrit eligibility criteria. Double red cell donors must wait 112 days before their next blood donation attempt (any type).
Type your answer here... I don't know but within a couple weeks of giving a donation of double red blood, I suffered a heart attack. I am 55 years old and have been giving blood for about 40 years several times a year. I am healthy and never had issues before. That was the first time I had ever given double red blood.
and a red blood cell or in a red blood cell? if its in a red blood cell i would say haemoglobin
There are 500 white blood cells to every 1000 red blood cells (or you could say there is double the amount of red blood cells). The answer would be 200 red blood cells for every 100 white blood cells.
The white blood cell has nucleus that red blood cell does not
a red blood cell is red when it reaches oxegen.
The biggest difference is that a red blood cell has no nucleus where as a white blood cell does. A red blood cell has no nucleus because it needs all the space inside the cell for the haemoglobin which is stored inside it and is the oxygen attrcting chemical. White blood cells can have either a bean shaped nucleus which would make it a lymphocyte or a double lobed nucleus which would make it a phagocyte. Another difference is that white blood cells are bigger than red blood cells.
The FDA has issued a draft Guidance recommending all allogeneic, and selected autologous, blood donations be screened for T. cruzi.
red blood cells are a type of cell
. The donation process includes registration, a brief medical screening, the blood collection, and time for refreshments in the canteen. For whole blood the entire donation process usually takes about one hour. It can take a little longer for platelets or double red cells.
