Abstract: ABSTRACT Hemoglobin (Hb) concentration is a critical biomarker for diagnosing anemia and monitoring overall blood health. Traditional methods for measuring hemoglobin require invasive blood sampling, which can be painful, time-consuming, and unsuitable for frequent monitoring, particularly in vulnerable populations such as infants, elderly patients, and individuals with chronic conditions. The growing demand for patient-friendly, real-time health monitoring has driven the development of non-invasive hemoglobin measurement techniques that eliminate the need for venipuncture while maintaining accuracy and reliability. This study presents the design and development of a non-invasive hemoglobin monitoring device that employs optical seusing technology. Using spectrophotometry and advanced algorithms, the device analyzes the absorption of specific light wavelengths through the skin to estimate hemoglobin levels. The proposed device is compact, portable, and capable of providing instant hemoglobin readings, enabling continuous monitoring without the discomfort or risk of blood-borne infections associated with traditional methods. The device demonstrates high accuracy and repeatability when validated against standard laboratory hematology analyzers. Additionally, it incorporates user-friendly features, including a digital display, wireless data transfer, and alert systems for abnormal hemoglobin levels, making it suitable for home use, clinics, and remote healthcare applications. Its non-invasive nature not only enhances patient compliance but also allows for frequent monitoring, facilitating early detection of anemia and better management of chronic conditions. Furthermore, the glucose levels can also be examined as a future enhancement, broadening its application to multi- biomarker monitoring, thus expanding its role in comprehensive health diagnostics and disease management. In conclusion, this non- invasive hemoglobin monitoring device represents a significant advancement in point-of-care diagnostics. By combining optical sensing with intelligent signal processing, it provides a safe, efficient, and accurate alternative to conventional hemoglobin testing methods. Its application has the potential to improve healthcare outcomes, reduce the burden on laboratory services, and empower patients to actively manage their health
