Not sure what a blood test is carried out for? This article will give you an overview!
Blood tests have a wide range of uses and are one of the most common types of medical tests.
For example, a blood test can be used to:
assess your general state of health
check if you have an infection
see how well certain organs, such as the liver and kidneys, are working
screen for certain genetic conditions
There are two main ways to collect a blood sample, either using a venous or finger-prick method. This is what to expect from each type of blood test:
a venous blood test — a needle is used to puncture a vein, usually in your arm, and allows you to collect a large blood sample. This type of blood test can be used to test a full-range of biomarkers but is more invasive.
a finger-prick blood test — a lancet is used to prick your finger and allows you to collect a small blood sample. You can do this type of test yourself and it’s less invasive than a venous sample. However, while it can be used to test a wide range of biomarkers it’s not possible to test every biomarker.
Rightangled blood tests are a simple finger-prick test that can show you your current conditions and check the functionality of your organs, such as your thyroid.
Blood tests are a relatively non-invasive and common procedure that can help you see what’s working and what needs to be done.
