Iron status profile

Why would I take this test?

We need iron for healthy red blood cells, growth development and hormone production. We get the iron we need through the foods we eat, so diet is very important. Vegetarians can have low iron levels, women can be strongly affected due to heavy periods or pregnancy, and we tend to absorb less iron as we age.

Many health issues stem from insufficient iron. Most common is anaemia, where red blood cells become smaller and less able to transport oxygen around the body. Anaemia manifests as a lack of energy and concentration, pale skin and generally becoming less effective in fighting off germs and infections.

The iron status profile is a comprehensive test that measures the amount of iron circulating in the blood and how much is being stored in the body. Any deficiency or excess reported should be discussed, along with your medical history, with your GP.

How a test is done?

Our phlebotomist will tie a rubber band to your upper arm to make the veins more visible. They will swab to clean the arm, then a sterile needle attached to a tube is gently inserted into the vein and the blood is drawn into a vial (or vials if more than one test has been requested). Only one needle is used regardless of the number of tests or vials requested. The needle is removed, a plaster applied, and it’s done. You might get a small bruise around the needle mark.

Please wear loose clothing (for easy access to your arm) and let us know a preferred arm.

You can continue to take regular medication but check with your doctor whether any of your medications may affect test results.

It's easier to draw blood when:

• you are hydrated – please drink some water, especially in hot weather and for morning blood draws

• you are warm – please keep warm before the test

Fasting is required

A fasting test means:

• nothing to eat or drink, other than water, for 12 hours before the test, unless advised otherwise by your clinician.

• the test should be taken in the morning, before you have eaten

• no alcohol for 24 hours before the test, unless advised otherwise by your clinician.

• you should not take any iron pills or supplements for 24 hours before the test

• you can continue to take regular medication but check with your doctor whether any of your medications may affect test results

Can I have someone with me?

Of course, if that makes you more comfortable, you may have a friend or relative accompany you during a blood test.

When will I get my results?

Results returned in 24 hours

• Transferrin 

How do I get my results?

The certified laboratory report is emailed to us, and we can either:

• email directly to you

• email directly to you and/or to your GP. We will need your written consent to share any test results, but we will discuss this with you when you book your appointment

• give it to you in person at the clinic

We highly recommend you consult with your clinician to explain test results. They can also take into account your medical history and advise you on next steps.
