blood type o negative and diet

blood type o negative and diet

according to a recent study, around 1 in 2people in the united kingdom do not know their own blood type. whether or not you know yours- you would have surely heard of there being many different blood types, with most peopleknowing of a, b ab and o. this begs the question though: why are theredifferent blood types? firstly, your blood group classification isall based on whether or not you have specific

blood type o negative and diet, antigens on the surface of your red bloodcells. the abo system is the blood group system whichmost people are familiar with. this puts you into one of four groups, a, b, ab or o.those in group a have a antigens on their red blood cells and anti-b antibodies in theirplasma. those in group b have b antigens on

their red blood cells and anti-a antibodiesin their plasma. those in ab have a and b antigens on their red blood cells but don’thave anti-a or anti-b antibodies in their plasma. group o has no antigens but has bothanti-a and anti-b antibodies in their plasma. your immune system attacks red blood cellswhich have the wrong anti-gen, which is why knowing your blood type is important for bloodtransfusions. you then hit the second most significant bloodgroup system, which is the rh blood group system which contains about 50 antigens. d, c, c, e and e are the most important outof the 50, but we tend to refer only to the d antigen the most due to it being the mostlikely to initiate an immune system response.

about 85% of the united kingdom is rh(d) positive,meaning that the rh(d) antigen is present on their red blood cells. this means we now have eight different bloodgroups. o-, o+, a-, a+, b-, b+, ab- and ab+. with a + sign indicating the presence of therh(d) antigen. things begin to get complicated when we beginto consider which blood groups can donate to each other. those with o- blood are called universal donators,because any blood group is able to receive their blood type. ab+ on the other hand areuniversal recipients because they are able to receive any blood type from any group.

this all however assumes there is no unusualantibodies which would cause an incompatibility between the donor and receiver, as there aremore blood group systems. being rh(d) positive is quite an advantagethan being negative, because those who are positive can receive both positive and negativerh(d) blood, unlike negative who can only receive negative. it is thought that these different blood groupsevolved during several millions of years. one theory says that blood group a came fromeurope, b from asia and o from south america, and that due to migration all of these havemixed. another theory is that blood group a and bare mutations of the o blood group, which

has happened over millions of years. even 115 years on from finding the abo bloodgroup, we still don’t have much of an idea of where these different blood groups reallycame from. if you would like to donate blood, click onyour countries flag for more information and if it isn’t displayed, be sure to googlesearch ways in which you can donate blood if you wish to. thanks for watching and be sure to subscribe.

you probably know your blood type -- a? b? universal donor? you might even carry a card on you so that in case of emergency, blood type diet o rhesus negative, you won’t get the wrong type of blood. but do you know how your blood type was actually identified in the first place? blood type can be determined in two ways: forward blood grouping which detects markers on the blood cells themselves, and reverse blood grouping, which detects antibodies present in the blood plasma either type of test today takes a long time, requires technical training, and can be expensive researchers have been working on a new blood typing test that is not only easy to use, but can be done on site -- in as little as 30 seconds a small blood sample is dropped into the middle of the testing strip a color change in either observation window delivers the results this test can perform forward and reverse blood grouping at the same time which gives more confidence in the result a similar test can also b...
