About this test
Measures ferritin, a marker of stored iron. A low result can support iron deficiency, while inflammation and other conditions can raise ferritin, so it is best interpreted with symptoms, a full blood count and other iron markers.

What this test measures
- Ferritin
- A protein used as a marker of stored iron. A low result strongly supports depleted iron stores. A normal or raised result does not always exclude iron deficiency because inflammation, liver conditions and other factors can raise ferritin.
How clinicians use this test
Clinicians use Ferritin to investigate relevant symptoms, monitor a known condition or add context to a broader health assessment. The result can support a diagnosis or next-step decision, but it is not a diagnosis on its own.
Is this the right test for you?
This may suit someone who specifically wants to check Ferritin, or repeat the marker(s) as part of an established monitoring plan. It is a focused test and may not include related markers needed to explain an abnormal result. The test should not delay assessment of persistent or worsening symptoms.
Preparation and collection
Return the sample on the same day it is collected. Do not post over weekends or bank holidays.
Understanding your result
The laboratory will report Ferritin with an assay-specific reference range, threshold or qualitative interpretation. Read the biomarker explanation above for common reasons a result may be high, low, detected or reactive, then use the laboratory comment and clinical context to decide whether repeat or follow-up testing is needed.
Your results and next steps
Review Ferritin against the reference range and laboratory comment, then consider whether the pattern fits your symptoms, medicines and reason for testing. Share a concerning or unexpected result with a clinician before changing treatment, supplements or diet.
Limitations
The result is a snapshot from one sample. It cannot diagnose a condition on its own; values inside or outside a reference range require clinical context.
When to get medical help
Do not wait for a home-test result if you feel seriously unwell. Call 999 for a life-threatening emergency, or use NHS 111 when you need urgent advice and are unsure what to do.

Questions, answered
How accurate is an at-home test?
Your sample is processed by a professional UK partner laboratory using the same analytical methods used for clinician-requested testing. Sample quality depends on following the collection instructions carefully.
Are my results private?
Yes. Kits use discreet packaging and your results are delivered through a secure digital service.
Does this diagnose a condition?
No. The test checks and measures biomarkers. Results and the doctor’s comment can help you decide what to discuss with your GP.
When should I post my sample?
Collect and post on the same day, ideally Monday–Thursday, to avoid a sample waiting in the postal system over a weekend.
What happens if my sample cannot be processed?
The support team will explain the next step if the laboratory cannot process your sample. Any recollection or refund depends on the circumstances and the applicable policy.
When should I speak to my GP?
Speak to your GP if symptoms persist, worsen or concern you. Seek urgent medical help for severe or sudden symptoms.
