SELFCHECK Iron Level Test - Data Sheet for HCPs
PRODUCT: SELFCHECK IRON LEVEL (FERRITIN) TEST
PRODUCT CODE: SCFER1
REVISION DATE: 16th July 2025
Test Principle and Specifications
Intended use
The SELFCHECK Iron Level Test is a manual, qualitative, solid-phase immunochromatographic (lateral flow) immunoassay for the detection of ferritin in a finger-prick whole blood sample.
Clinical Context and Limitations
This is a screening test and is not intended for diagnosing iron deficiency. A single ferritin test result should not be the sole basis for a clinical decision. A full clinical evaluation of iron deficiency anaemia by a healthcare professional is required to fully interpret results in the context of the patient's overall health and symptoms.
All medical tests, whether used in a hospital laboratory or at home, have limitations and carry a possibility of false positive or false negative results due to individual physiological variations and interpretation of the instructions for use (IFU). This test should be used as one part of a broader approach to health management, including healthcare professionals.
The test is not suitable for patients with haemochromatosis.
