Stopping iron supplement

[giggy63]

Hi all hope everyone is well. I am going to have a iron blood test. How many days before the test do i stop my iron supplement?

A week…. So anywhere from 5-7 is safe.

Avoid iron rich foods the day before as well.

Just to add to the advice given by FallingInReverse...

Also, fast before the blood draw for 12 hours, like you would for thyroid function tests. Water can and should be drunk freely during the 12 hours fasting - being dehydrated should be avoided. It is also best to test first thing in the morning (just like thyroid testing).
