Abstract: Provided herein are systems and methods of assessing a concentration of iron in a body fluid sample, such as whole blood. Systems include a highly stable, fast reacting, and accurate sensing area of a sensor for contacting with a body fluid sample, wherein upon contact, the body fluid sample causes a color change to the sensor that correlates with the concentration of iron in the body fluid sample. The disclosed systems and methods generate one or more signal outputs of light intensity data, from which the concentration of iron in the body fluid sample is determined.
