A blood test is when a sample of blood is taken for testing in a laboratory. Blood tests have a wide range of uses and are one of the most common types of medical test. For example, a blood test can be used to:
CAN I EAT OR DRINK BEFORE A BLOOD TEST?
It depends on the type of blood test you're having. The healthcare professional who arranges your blood test will tell you whether there are any specific instructions you need to follow before your test.
You can eat and drink as normal before some blood tests. In other cases, you will be instructed not to eat or drink (other than water) before your test. This is known as a fasting blood test. You may also be told not to drink alcohol or not to smoke before your test.
If you have any questions about your blood test, ask a healthcare professional, such as a GP or nurse, for advice.
Below are some examples of different blood tests and what you may need to do to prepare for them, including how long you may need to fast. However, you should also follow any instructions from your healthcare professional.
Do not eat or drink anything except water for 8 to 10 hours before a fasting blood glucose test. These are used to diagnose diabetes, a condition caused by too much glucose (sugar) in the blood.
Iron blood tests are usually taken in the morning before you eat anything. You should also avoid taking iron pills or tablets for 24 hours before your test. Your body absorbs iron very quickly from food or pills, so this can raise your iron levels and affect the test results.
Iron blood tests help diagnose conditions such as iron deficiency anaemia (lack of red blood cells caused by low iron levels).
You may be asked not to eat anything and only drink water for 9 to 12 hours before having blood cholesterol tests (lipid profile).
There are several different cholesterol tests. When these are done together, it's called a lipid profile. A lipid profile tests the levels of:
If you're just having a triglycerides test, do not drink alcohol for 24 hours before the test (you'll also need to fast, as explained above).
Gamma-glutamyl transferase (GGT) test
A GGT test is used to help diagnose liver disease. Your GGT levels may be affected if you drink alcohol in the 24 hours before the test. Smoking can also affect the test results. Your healthcare professional will advise you about not drinking and smoking before the test and how long for.
An X-ray is a widely used diagnostic test to examine the inside of the body. X-rays are a very effective way of detecting problems with bones, such as fractures. They can also often identify problems with soft tissue, such as pneumonia or breast cancer.
If you have a X-ray, you will be asked to lie on a table or stand against a surface so that the part of your body being X-rayed is between the X-ray tube and the photographic plate.
An X-ray is usually carried out by a radiographer, a healthcare professional who specialises in using imaging technology, such as X-rays and ultrasound scanners.
You can find out more about x-ray tests, how they are performed, their function and the risks by visiting the NHS Choices website.
