Phlebotomy (Blood Tests) FAQs

How do I prepare in advance of my Blood Tests?

Most tests don't require any advance preparation. The exceptions are:

Fasting Bloods - You must fast for 14 hours from the night before. Check with your doctor/ nurse if you need to fast in advance.

24hr Urine Collection - Please ensure to follow the instructions given to you about the collection details carefully and remember, any Phlebotomy required during the 24hr collection period must happen within that time otherwise, the 24hr collection may have to be repeated.

What do I bring with me?

If your doctor/nurse has given you a note during your last most recent visit, it is essential that you bring this with you to present to the Phlebotomist (Blood-Taker).

What do I do when I arrive at Phlebotomy?

The Phlebotomist will call you in turn. Let staff know of your arrival and they will schedule you for your turn to get your blood taken.

What exactly will happen when my blood is being taken?

The Phlebotomist puts a tourniquet around your arm just above the elbow and inflates it gently. Then he/she and gently inserts a small needle just below the tourniquet and quickly withdraws just enough blood needed for all tests. Afterward, he/she places a piece of cotton wool on your arm covering it with a small plaster.

Why is my blood put into different bottles?

Some of your tests may require that your blood be preserved in different ways for the best quality results. Also different test-types may require separate bottles. That's why more than one bottle might be needed. For more information about what tests the laboratory does, see Pathology Tests

How long will my results take?

Most results of tests performed on-site are reported by the laboratory back to the requesting doctor generally within a couple of days with the exception of Tumour Markers which may take up to a week. Any queries you may have regarding your results should be made to your doctor.
