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:
- assess your general state of health
- confirm the presence of a bacterial or viral infection
- see how well certain organs, such as the liver and kidneys, are functioning
A blood test usually involves the phlebotomist taking a blood sample from a blood vessel in your arm. and the usual place for a sample is the inside of the elbow or wrist, where the veins are relatively close to the surface. Blood samples from children are most commonly taken from the back of the hand. The child's hand will be anaesthetised (numbed) with a special cream before the sample is taken.
If you are advised you are to have a 'fasting' blood test - please ensure you have nothing to eat for 14 hours before your phlebotomy appointment, but drink plenty of water and take any essential medication.
From 1st July blood tests will be carried out within our Practice. Until this date, patients can continue to fully utilise the phlebotomy service offered at the Victoria Central Walk-in Centre in Wallasey, and St Catherine's Health Centre in Birkenhead.
Please have your request form to hand when booking an appointment as they will ask for information from the sheet regarding the tests you require.
