Blood: – Do you know what to do?
In this article we would like to shed some light of the mysteries of blood. so here are a few of the questions?
Why are we asked for blood tests?
What is the significance of high blood pressure?
What is the significance of low blood pressure?
Blood groups, what do they mean?
Some of the most common reasons to have a blood test is in order to assess your general state of health. Infections can often be identified with a blood test as well as giving an indication as to how well your organs such as your liver and kidneys are working. Blood test can also be used to screen for certain generic conditions. The list of conditions, be that about your current state of health, infections or generic conditions is immense therefore in most cases the blood test is often qualified to look for suspected conditions.
What about eating and drinking before a blood test?
Well it depends on the blood test you are having. Let’s say for example you are having a fasting blood test for diabetes you will probably be asked to fast for 8 – 10 hours before the test, or maybe an iron test for iron deficient anaemia it could be 12 hours. Your doctor will advise the time required and the reasons why.
High & Low Blood Pressure:
We would like to thank and acknowledge the NHS for the excellent insights into high and low blood pressure. Please see the link below to check your blood pressure results and how to interprete the results. The results also give you an idea of what to do next.
Blood is made up of red blood cells, white blood cells and platelets in a liquid called plasma. Your blood group is identified by antibodies and antigens in the blood.
Antibodies are proteins found in plasma. They’re part of your body’s natural defences. They recognise foreign substances, such as germs, and alert your immune system, which destroys them.
Receiving blood from the wrong ABO group can be life threatening. For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells.
This is why group A blood must never be given to someone who has group B blood and vice versa.
As group O red blood cells don’t have any A or B antigens, it can safely be given to any other group.
