Blood Group

Blood Typing and Blood Group

The cell wall contains many antigenic proteins, which determine the blood type. Among these proteins are the antigens. A and B, the major blood group factors. Blood with antigen B is group B. Blood with both antigens is called AB, and blood with neither is called group O. Normally, the plasma of every person contains an antibody against the A or B antigens in the red cells are determined by mixing the cells with known typing serums.

The antibodies in the serum or plasma are determined by mixing it with cells of known A or B type. Such typing is necessary in preparation for blood transfusion. Antigens of the various Rh and Hr types, M and N, S and Kell, Duffy, and many others also exist in the red blood cell. All like the A and B antigens, are inherited. When the red cell antigens are determined, they show so many different combinations as to make a persons blood type almost as individual as a fingerprint.

Antibodies against antigens other than A and B do not normally occurs in the plasma. They may appear after transfusion, however, and may cause transfusion reactions and destruction of red blood cells or hemolytic disease of the newborn.

According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).

Blood group A

If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.

Blood group B

If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.

Blood group AB

If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.

Blood Type O

Why are some people plagued by poor health while others seem to live healthy. Does blood type influence personality? A single drop of blood contains a biochemical make up as unique as your fingerprint. Your blood type is a key to unlocking the secrets to your biochemical individuality. Foods and supplements contain lectins that interact with your cells depending on your blood type. This explains why some nutrients which are beneficial to one blood type, may be harmful to the cells of another.

Blood Donor Requirement

Blood donor is required by every patient who need additional blood because of shortage of blood inside the body. The shortage of blood inside of somebody can because of injure or because of diseases. Severe injure can make people die if blood shortage can’t be overcome as soon as possible. After the blood requirement can be fulfil, victim can recover their wound and back to normal. Whether shortage of blood because of certain disease, can’t be overcome in a simple way. First he/she must be cured from the causes beside must give any additional blood into the body.

Blood donor should be fulfil a certain condition, that currently more strict year by year because of many diseases can make problem to the blood recipient. Following below are the major reasons given for exclusion, most still in force in Blood banks, Blood donor clinics and hospitals, today.

In 1980s, the blood donor must don’t have this:
  • Cancer
  • AIDS Symptoms
  • Hypodermic drug use
  • Men having had sexual contact of any kind with another man or men since 1977.
In 1990s, the blood donor must don’t have this, beside the above diseases:
  • Anyone who has had hepatitis since his or her 11th birthday
  • Anyone who has taken pituitary growth hormone in any quantity.
In 2000 to the present, in addition to all of the above:
  • Anyone who has taken Tegison for psoriasis
  • Anyone currently with drugs for an enlarged prostate in their system
  • Anyone who spent three months or more in the United Kingdom from 1980 through 1986
  • Anyone who has received Blood by transfusion in the United Kingdom or France from 1980 through the present
  • Anyone who has spent five years in Europe from 1980 through the present time.
  • Anyone who has self-administered non-prescription drugs intravenously
  • Anyone who is not 17 years old and 110 pounds in weight or more.

Ebola Virus Diagnosis in Blood

In the first few days after infection with Ebola Virus, symptoms resemble those other diseases such as general fever, headache and muscle aches like when you will got flu. The disease rapidly to more serious symptoms such as rash, chest pain, severe bloody vomiting and diarrhea, uncontrolled internal bleeding, kidney and liver failure, and then shock.

Doctor can diagnose Ebola fever based on the symptom seen or you reported to them, as they quickly become ill during outbreaks. Blood tests can sometimes identify the virus directly, or antibodies to Ebola produced by the body during infection can be detected in blood. Doctors have to be careful when performing tests because simply injecting a needle into a patient who is prone to hemorrhage can trigger uncontrolled bleeding.

Until now there is no medication to treat or cure Ebola infection. Patients with Ebola fever are hospitalized and receive supportive care to treat symptoms, it mean if the patient shows cold, doctor will give anti cold or paracetamol medicine. They may receive intravenous fluids to protect against dehydration; monitor of blood pressure, heart rate and breathing and also treat for bleeding or other infections that may develop during the illness. During past outbreaks, 50 to 90 percent of people who developed symptoms of this disease died. Those who survive usually recover in several weeks.

After research, found that protein on Ebola virus attack blood vessels, and this finding may helps to explain the massive bleeding that leads to most Ebola death. The researchers then try to find new drugs or vaccine against this protein, which might prevent the disease or at least reduce the severity of the symptoms and the number of deaths caused by the virus.

Why Blood Price Expensive

This question always come after the patient getting blood transfusion because of their suffer of blood shortage, as an example of the story on certain hospital as follows:

A 20-month old son was recently hospitalized with acute anemia. It was eventually diagnosed as Transient Erythroblastopenia of Childhood, but at the time all we knew was his hemoglobin level was 2.3 grams / deciliter, which I've been told is extremely low. He received 4 transfusions of packed red blood cells, totaling 240 cc of blood, or just over 8 ounces. He has thankfully recovered fully. The hospital thoughtfully sent us a copy of the invoice they submitted to the insurance company which contained the following charges:

blood processing /storage $1500
blood / admin $2500

WTF? Four thousand dollars for 8 ounces of blood? 500 simpletons per fluid ounce? Why is the stuff so damned pricy? I understand its not available on tap, and it requires screening and storage and whatnot, but that seems very expensive. Is there just one hell of a markup on the stuff?

They always asking about the price, why is it so expensive, while many people always blood donor for free. The answer always many factor involved like the blood process also expensive, the transportation and many other reasons. So the Vampire live very difficult because no blood available on the store.
