Abstract
This paper presents a simple and portable body iron reader to analyze the concentration of iron via colorimetric analysis. Through this approach, early diagnosis can be made for diseases such as iron deficiency anemia (IDA) and thalassemia. The uses of spectrophotometer to analyze a concentration of analyte in a sample can be reconsidered. Spectrophotometer nowadays is bulky and very expensive. The proposed portable reader can gives the user a result of concentration of analyte in a sample solution almost the same as the commercially available spectrophotometer. Through a comparison, the portable body iron reader managed to obtain a 0.9986 coefficient of determination value which has only 0.13% of error. Moreover, this device can works with a battery without the needs of power source.

A simple and portable spectrophotometer to be used as body iron reader has been proposed in this paper
The portable iron reader could help in solving problems in detecting patients with anaemic diseases in an early stage, especially for the people living in poor countries and rural areas
Summary
Blood plasma stores a lot of proteins that resemble the health condition of a person. Kittipannyangam et al reported a low-cost battery-powered light absorbance device to be used in analytical measurements [4] Their device utilized the uses of red, green and blue light emitting diode (LED) despite the usage of monochromator or wavelength selective filter as it can reduce space. Another device reported for analytical measurement is the simple, low power; inexpensive and microcontroller-based (SLIM) spectrometer by Cantrell et al that uses thionine as an analyte [12]. The device has a potential to be a low-cost colorimeter for detection of iron concentration in blood plasma, especially in poor and rural areas
