What happens on the day

Printer-friendly version

If you're new to donating or haven't donated for a while, the information below describes how you should prepare for your donation and what to expect on the day.

Before your donation

  • The day before you donate, drink plenty of fluids, especially in warm or hot weather. Eating salty foods and snacks in the 12 hours before you donate will help you maintain your blood volume.  
  • Make sure that you eat something in the three hours before you donate. Savoury and salty foods are best as they help to restore your blood volume rapidly.
  • In the 3 hours before donating, you should drink at least 3 good-sized glasses of water or juice.
  • If you’ve got a cold or flu, had an upset stomach in the past week, or you’ve been to the dentist recently you may not be able to donate. Call us on  13 14 95 to find out and we can reschedule your appointment if necessary.
  • If you take any medications, it may be worthwhile writing down a list of what medications you are currently taking.  This will assist our staff in accurately assessing your eligibility.

On the day of your donation

  • Bring identification with you. Acceptable ID is a document (or combination of documents) which contains 3 unique pieces of personal information. These can be:
    • Full name
    • Date of birth
    • Home address
    • Signature
    • Photo (if possible)

1. Arrival

  • Completing the donor questionnaireYou'll be asked to complete a questionnaire. This form is completely confidential and asks about your general health and is designed to protect both you and the person who receives your blood.
  • You can view the questionnaire below. Please note this is a sample only and not for actual use. It should not be taken as a definitive guide to eligibility, which often requires medical interpretation.

2. Interview

Before donating you will be interviewed by a trained staff member to assess your suitability. You'll be given a quick 'finger prick' to check your haemoglobin level is within our acceptable range and your blood pressure will be measured.

3. Donating

  • Donating bloodGiving blood takes just 5-10 minutes but please allow about 60 minutes from arrival to departure. This includes time for your interview and refreshments
  • Donating plasma or platelets takes about 45 minutes (allow 1.5 hours for the whole process from interview to refreshments)
  • Tense and relax your calf and thigh muscles for about 5 seconds three times every minute during and immediately after your donation
  • If you experience any discomfort or if you have any concerns, speak to a staff member immediately – we want to know how you are feeling

4. After your donation

After donating blood, you should rest on the chair for around 2-3 minutes.

  • When you are ready, you should sit on the side of the couch with your legs over the edge for a couple more minutes, before moving through to the refreshment area
  • Stay for at least 15 minutes in the refreshment area and have a cool drink and a savoury snack
  • Take a bottle of water or sports drink with you and drink it over the next hour

To help you recover quickly from your donation:relax and refresh after your donation

  • drink plenty of water, fruit juice etc.
  • avoid alcohol for 8 hours and avoid smoking for 2 hours after your donation

5. For the next 6 hours

  • You should drink plenty of water/juice (at least another 3 good–sized glasses)
  • You should avoid strenuous exercise (e.g. riding your pushbike, jogging, going to the gym) and you should avoid prolonged standing (e.g. waiting in a long queue, or standing on crowded public transport)
  • Don’t get overheated – avoid hot showers, sitting or standing in the direct sun and choose cool drinks rather than hot drinks

If you become unwell in any way or have any questions after giving blood, call us on 13 14 95.

Safety

All equipment is sterile; needles are used only once and then discarded. In the great majority of donors, a donation of 470mL is less than 10% of your total body volume and may be given safely every 12 weeks.

Testing

To protect patients who receive blood, your donation is tested to determine your blood group and will be screened for HIV 1 & 2, hepatitis B & C, HTLV I & II and syphilis.

Make your next appointment

Before you leave the donor centre book in your next appointment

  • Whole blood donors can give blood again in 12 weeks
  • Plasma and platelet donors can donate as often as every 2-3 weeks
