If any of your supplements contain iron stop taking it for about 5 - 7 days before the test.

Also on the day before the test don't eat a very high iron dinner e.g. a full English Breakfast or a liver dinner.

Also, fast for 12 hours before the blood is drawn, except for water which should be drunk freely.

Do the blood draw first thing in the morning, before eating or drinking anything except water.
