Check your body's iron reserves at home with a simple finger-prick blood test.

The Prima Iron FER Test measures ferritin, the protein your body uses to store iron, in a whole blood sample. Ferritin levels are one of the best indicators of how much iron you have in reserve, making this test a useful first check for people who suspect low iron.

Who It's For

Anyone wanting to check their body's iron reserves, including people feeling tired or run down, or those monitoring known low iron levels.

Frequently Asked Questions

How accurate is this test?

Lab studies show 96.6% overall accuracy for detecting ferritin below the 30 ng/mL cut-off.

What does a positive result mean?

A positive (low) result means your ferritin is below 30 ng/mL and it's worth speaking to your doctor about your iron levels.

What if I don't read the result within the stated time?

Read the result at exactly 5 minutes — results outside this window may not be reliable.

Can borderline results happen?

Yes, ferritin between roughly 27–29 ng/mL can sometimes give a similar reading to just below the cut-off, so borderline results are worth rechecking with a doctor.
