FerroSens – Reliable non-invasive iron deficiency testing at the point of care.
About us

FerroSens offers a method to screen for iron deficiency at the point of care, which is

FerroSens GmbH is a spin-off of the Laser Research Laboratory, an institute of the LIFE Center, at the University Hospital Munich. The company was founded in July 2017 with the main office in Munich (Germany), driven by the WHO’s proclaimed research priority to develop a very cost-effective, portable, reliable instrument to measure the iron parameter Zinc Protoporphyrin.

After several years of extensive research and development, clinical studies on close to 1.000 participants showed the high reliability and accuracy of the newly developed non-invasive measurement technique. This was the right time for the foundation of FerroSens GmbH, who launched FIDscreen, the first non-invasive point-of-care testing device fulfilling the WHO’s requirements.

FIDscreen enables wide-spread screening for iron deficiency through its simple and fast non-invasive method without the need for blood withdrawal. In this way, FerroSens helps to fight iron deficiency, the world's most common nutritional deficiency.

Iron deficiency

Research Priority

Development of an inexpensive, portable, reliable instrument to measure the iron parameter Zinc Protoporphyrin (ZnPP).

*WHO. Food Nutr Bull 2007; 28:S621-S627


Worldwide, 500,000,000 children suffer from iron deficiency.
In China 32.5 % of all children between 7 months and 7 years are iron deficient.


Iron deficiency in childhood impairs the cognitive development and leads to a lower IQ. Iron deficiency also weakens the immune system.


ID can be easily treated, however most persons affected are unaware of their need for iron. This is because no suitable screening test is available, as all existing methods require a blood withdrawal and laboratory processing.


Currently, iron deficiency detection requires a blood withdrawal. This is a hurdle in many settings, leading to a low screening coverage. Especially for children, the blood withdrawal is stressful and causes pediatricians to refrain.


Iron deficiency markers are often unreliable: The most often determined parameter hemoglobin indicates only anemia, a late consequence of iron deficiency. Other parameters as ferritin are incorrect under certain health conditions (e.g. inflammation).


The blood tests for iron deficiency are typically performed in an external laboratory. This leads to a delayed result and increases costs.


The determination of reliable iron deficiency parameters is expensive. Especially resident pediatricians have no economic benefit when ordering blood tests.

FIDscreen Technology

FIDscreen is a medical device for the detection of zinc protoporphyrin (ZnPP), an established marker for iron deficiency. FIDscreen is based on an optical method, fluorescence spectroscopy and an elaborate data evaluation to obtain a quantitative measurement of ZnPP. The measurement is performed on the lower lip of an individual and takes about one minute.

Vision & Trends



Our device can detect lead poisoning, which is still an acute problem in many countries world-wide, including the US where still more than 6.1 m homes have lead pipes.


The trend to vegetarian and vegan diets increases both the risk and the awareness for micronutrient deficiencies, especially iron deficiency. This increases the demand for FIDscreen measurements.


Improved physical performance by avoiding iron deficiency anemia. With FIDscreen, sport clubs can offer regular tests for iron deficiency.


Privately paid iron deficiency testing avoids the visit of the medical doctor.
