What to expect when having a Blood Test

You have been asked to have a blood test either by your Doctor or for routine monitoring because you are on regular medication.  Unless you bring a form from the hospital, your GP will have requested which blood tests are required. Please discuss any results with your Doctor.

  • You may have been asked to fast (not to eat or drink) for 12 hours before your blood test. However, you may take any medication that you normally take. It is advisable to drink plenty of plain water. If you are diabetic your doctor will probably not ask you to fast.
  • When you attend for your appointment your details will be checked to confirm your name and date of birth. The procedure will be explained to you.
  • To make sure their hands are as clean as possible before touching your arm the Nurse will have washed his/her hands before you enter the room. They will then apply special gel and may wear protective gloves. It is not necessary for your arm to be swabbed with an alcohol wipe prior to having blood taken; in fact it is not advised.
  • A tight band will be placed around your arm. This may feel a little uncomfortable, but should not be painful and will only last for a very short time.
  • The Nurse will feel for a suitable vein. Once the vein has been found you will be warned that there will be a small sting or scratch.  This is the needle going into your vein.
  • When all the vials have been taken the band on your arm will be removed. The needle will be removed and you will be asked to apply firm but gentle pressure to the pad placed over the site.  Pressure reduces the likelihood of bruising.
