The red blood cell (RBC) count determines the total number of red cells (erythrocytes) in a sample of blood. Examination of the erythrocytes provides the doctor/physician with information concerning anemia-related problems and the bone marrow response (which is where RBC's are produced). \nAnemia is basically deficiency of blood in common language.\n\nWhite blood cells (WBC's) are part of the body's defense or immune system.The WBC count provides clues about certain illnesses, and helps physicians monitor a patient's recovery from others.\nBasically WBC count says all about our immunity.The elevation or decrease in WBC decides our disease-eg leukemia.For a layman, yes WBC says about immunity.\nYou want me to give more details??

Blood substitutes, often called artificial blood, are used to fill fluid volume and/or carry oxygen and other gases in the cardiovascular system.Blood substitutes can be stored for much longer than transfused blood, and can be kept at room temperature. Most hemoglobin-based oxygen carriers in trials today carry a shelf life of between 1 and 3 years, compared to 42 days for donated blood, which needs to be kept refrigerated.Blood substitutes allow for immediate full capacity oxygen transport, as opposed to transfused blood which can require about 24 hours to reach full oxygen transport capacity due to 2,3-diphosphoglycerate depletion.

Blood's role in the body is three fold: First, it acts as a transort system for nurtients and such to reach the different parts of the body. Secondly as a defence system, where lymphocytes are active in controlling pathogens that enter the body (such as bacteria, viruses, fungi, etc). Lastly, the blood acts as a sealant. When there is damage to the body, the platelets in the blood seal up the wound.\n\nBlood is very important to the body. Without it, you wouldn't exist.

Yes, you're absolutely right.\n\nMy husband and I can't give blood because of earlier health problems, but my (grown up) children do.\n\nEven the youngest, who is TERRIFIED of needles. She does it because other donors saved her dad's life.

Right after the donation the blood components are separated into Platelets ( good for 5 days), Plasma ( frozen good for 1year) and red blood cells ( good for 30 days). The testing is done on the extra tubes taking during donation. Testing is done for some chemistry, infectious disease ( HIV, west Nile, Hepatitis B, C, and many more). The blood is typed (A,B,AB,O and RH+/-). It is also tested for poss. bacteria contamination. A complete blood count is performed. After all the test pass acceptability, the components are released to be given. All components are constantly monitored regarding the storage temp.\nBefore blood components are given the recipient is tested to be compatible to the product. ( same blood type and compatible cross match with the donor).\nThe is a lot of checking and double checking involved in blood banking. If you need more or specific info just e-mail me.\nbeen working in blood bank for 20+ years.

I give blood all the time but I never have gotten paid for it. It isn't unheard of thugh. Otherwise, I've always had a good experience with it. You could pass out and depending on the person doing it you could get bruising around the area and there are always very small risks of infections. It's bad if you're anemic but they test for that before hand. If you d, be sure to eat first fruits/grains and sweets are good and they usually provide cookies. Also drink a lot of water or juice. The only things that have ever happened to me was being really tired for like an hour afterwards.

Certain diseases would prevent you from being a donor, specifically if you'd ever had hepatitis.\n\nThe general rules for donating blood when one is taking insulin or other medication that may cause allergic reactions seem to apply. \n\nWith possible concerns of mad cow disease (bovine encephalopathies), there may also be some general rules about avoiding any contact with beef product of any kind. Since bovine insulin might have some slow virus contamination, this would be a conservative recommendation to avoid any possible cow products of any kind.

Iron function:\n\n• Iron is needed for the formation of hemoglobin, which carries oxygen from the lungs to the body cells.\nIron sources:\n\n• Iron is found in meats, eggs, dark green leafy vegetables, legumes, whole grains and enriched food products.\n\nIron- rich Foods\nIIf you are going to donate blood beforehand, and to minimize the necessity for transfusion, it is necessary  to increase  iron intake both before and after the surgery.  We try to avoid iron tablets as they are quite constipating.   A diet that includes foods that are high in iron is sufficient.  The following is a partial list of foods that contain larger amounts of iron. \n\ntop ten iron rich foods \n\n·  clams, cooked, 3 oz (23.8 mg) \n·  tofu, 1/2 cup firm (13.2 mg) \n·  raisin bran, ready-to-eat, 3/4 cup (4.5 mg) \n·  sirloin steak, cooked, 3 oz (2.9 mg) \n·  shrimp, cooked, 3 oz (2.6 mg) \n·  black beans, boiled, 1/2 cup (1.8 mg) \n·  chickpeas, canned, 1/2 cup (1.6 mg) \n·  turkey breast, 3 oz (0.9 mg) \n·  bread, whole wheat, 1 slice (0.9 mg) \n·  chicken breast, skinless, 1/2 breast (0.9 mg)\n\n \n \n  \n\nIron-rich Foods for Blood Donors \nIn order to help maintain adequate blood iron levels throughout autologous and directed donations, donors should eat foods high in iron. The following list gives the iron content of selected foods. \n\nFood \n Serving Size \n Iron Content (mg) \n \nCereal, ready to eat, fortified \n 1 cup \n 1 to 16 \n \nClams, canned \n 1/4 cup \n 11.2 \n \nBeef liver, fried \n 3 oz \n 5.3 \n \nBraunschweiger \n 2 oz \n 5.3 \n \nMolasses, blackstrap \n 1 tablespoon \n 5.0 \n \nBaked Beans \n 1 cup \n 5.0 \n \nOysters, cooked \n 1 oz \n 3.8 \n \nBaked potato, with skin \n 1 \n 2.8 \n \nSoup, lentil and ham \n 1 cup \n 2.6 \n \nBurrito, bean \n 1 \n 2.5 \n \nSoup, beef noodle \n 1 cup \n 2.4 \n \nRice, white, enriched \n 1 cup \n 2.3 \n \nPoptart, fortified \n 1 \n 2.2 \n \nGround beef, lean \n 3 oz \n 1.8 \n \nApricots, dried halves \n 10 \n 1.7 \n \nSpinach, frozen \n 1/2 cup (fresh=1 cup) \n 1.5 \n \nBread, whole wheat \n 1 slice \n 1.2 \n \nBroccoli, fresh cooked \n 1/2 cup \n 0.7 \n \nEgg \n 1 \n 0.7 \n \n\n\n\n\n\nAlso: \n\nVitamin C enhances iron absorption from plant sources -- drink orange juice with iron-rich foods. \n\nTea with meals can act as an iron blocker. \n\nOther iron blockers include carbonates, oxalates, and phosphates. Foods that contain these iron blockers include, cranberries, rhubarb, spinach, and soda

When you give blood the normal way without machinery you lose about a pound but don't count on keeping it off.  This is only temporary till you drink again and your body will take the opportunity to replace the fluids you lost.\n\nWhen you donate on machinery like with ALL plasma donations you can actually come out weighing more because you are being given a saline IV at the same time.\n\nThe machine I use takes out 360ml of blood from the body and returns 500ml of saline.\n\nBottom line, you will not lose weight from donating.

Are there any known side effects of blood donation?\nNo. Till date, there has been no medical proof of the side effects that blood donation might bring. Many have gone through the process without a hinch and from then saved the lives of million others.\nBlood donation is quick and safe and does not cost you a single cent.\n\nI suggest you discuss this problem with your doctor.

When I first gave blood, they sent me a donor's card that told me my blood type.  And then they told me on every piece of mail they ever sent me after that.  D@mn type O universal donor nonsense!  They don't tell you right away, though, because they don't do any sort of testing (other than the anemia one) on your blood there.  It takes awhile.  But they do send you something.\n\nYou aren't supposed to give more blood for a couple of months after you donate.  Doctor's offices do take a pretty small sample, though.  However, just to be safe, I'd wait to give until after the physical, and ask my doctor while I was there.

It is not harmful to you to donate blood, so long as you are in good health at the time of the donation. The donor center will take a small sample of your blood first to test your hemoglobin and hematocrit, to make sure you can safely donate. They will also ask you a health history to make sure that it is safe for you to donate, and that your blood is not at risk for having any viruses that could be spread to others. (Be prepared to be asked some very personal questions about your life, such as sexual history, IV drug use, and so on. This is confidential but meant to keep the blood supply safe.)  \n\nAfter donating, you should drink plenty of fluids (NOT alcohol, as it actually dehydrates you worse) and preferably eat a light snack.  You can only donate once every 56 days, to allow your body a chance to regenerate the lost blood cells.\n\nAs to whether it is painful, the needle used has to be fairly large to keep the blood from clotting in it. (You don't want to get stuck for nothing, do you?)  The nurse or technician who does the venipuncture ("stick") will tell you when to expect it, and it only lasts a second or two usually. Not a bad trade for the satisfaction of helping to save a life.
