The HemoCue Hb 301 system is a compact, portable hemoglobin testing device used for quick, accurate measurement of blood hemoglobin levels at the point of care. It works with HemoCue 301 test strips, delivering results in about 5–10 seconds from a small blood sample (capillary, venous, or arterial). This makes it ideal for clinics, hospitals, screening events, schools, and community health programs where fast, reliable Hb readings are needed.
