Do you know what's in your blood?
Here at Medichecks, we have processed over 3 million results, many of which have been obtained from a blood sample. On average, an adult has around 5 litres of blood circulating around their body. We all know that the heart pumps blood around our body and that it’s crucial for keeping us alive but many people are unaware of all the components within our blood. Do you know what’s in your blood?
Blood is essential to life and has many important roles in the body including transporting and supplying oxygen and nutrients to our cells, removing waste materials such as carbon dioxide, protecting us from infection and transmitting signals from one area of the body to another.
Blood has 4 main components - plasma, red blood cells, white blood cells and platelets, each with their own roles.
Although our blood may look identical, the exact composition of blood is not the same in everyone. The surface of each red blood cell is coated with a combination of sugars and proteins called antigens. The absence or presence of particular antigens (which is determined by the genes you inherit from your parents), determines your blood type. There are 4 main blood groups, referred to as the ABO system: O, A, B and AB. Blood groups are very important when it comes to blood transfusions as receiving blood from the wrong ABO group can be life-threatening.
The rhesus (Rh) system is also important in blood transfusions. There are 5 main rhesus antigens on red cells with Rh D being the most important. The D antigen on red blood cells is what gives you gives individuals the positive (+) or the negative (-) after the letter A, B, AB or O of their blood group.
Blood is an invaluable window through which we can look into a person’s inner health - and just a few drops of blood is enough to get a huge amount of information about someone. It can tell us everything from hormone and nutrient levels, how much sugar we have in our blood, to our cholesterol status and organ function. You don’t have to be ill to benefit from a blood test - nothing puts a spring in your step more than a clean bill of health, and if something is amiss? Rest assured that many of the conditions we test for can be reversed through healthy lifestyle changes if caught early enough.
