Non-Invasive Testing Device for Anaemia

Anaemia (iron deficiency) arises from a reduction in the number of healthy red blood cells or the level of haemoglobin (Hb) (a protein inside red blood cells) necessary to effectively transport oxygen throughout the body. Anaemia is common among pregnant women. The gold standard for anaemia diagnosis still relies on laboratory blood tests, which come with limitations in terms of point-of-care capability, accessibility and quality. The investigators have developed a portable and user-friendly device capable of detecting anaemia rapidly and non-invasively and facilitating appropriate treatment by distinguishing anaemia due to iron deficiency from other causes. The device, named The Vascular Imaging Tool for the Auricle (VITA), utilises high-resolution imaging technology to capture detailed images of blood cells and small blood vessels within the human body. The objectives of this study are to assess VITA's performance of (haemoglobin (Hb)) testing and its ability to identify iron deficiency anaemia against the clinical gold standard of laboratory blood tests.
