Blood Tests

blood_tests_4A 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 Health Care Assistant or Practice Nurse 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. Children under the age of 12 require a Paediatric Nurse/GP appointment in the morning.

 

Fasting Blood Tests

Are done the same as a normal bloods test but you have to not eat or drink anything other than a sip of water if you are taking medication from 9pm the night before your appointment.

Oral Glucose Tolerance Test

This test is done to check for diabetes which consists of two blood samples being taken 2 hours appart. Like the fasting blood sample test the patient must not eat or drink anything other than a sip of water if you are taking medication from 9pm the night before your appointment. You will be asked to take 2 bottles of 380mls orginal lucozade to the appointment with you and drink it after your first blood sample is taken. You must then wait in the surgery for a further two hours until the second blood sample can be taken.
