POCT Hemoglobin Analysers: Principles, Use, and Clinical Significance
Point-of-care testing (POCT) hemoglobin analysers are portable devices designed to quickly measure hemoglobin levels in blood samples. These analysers are used in hospitals, clinics, emergency care, and field settings, providing immediate results for the assessment of anemia, blood loss, and overall oxygen-carrying capacity.
POCT hemoglobin analysers operate using optical, photometric, or electrochemical principles to quantify hemoglobin concentration. They require minimal sample volume, often a finger-prick blood drop, making them convenient for patients of all ages. Results are typically available within seconds to a few minutes, supporting rapid clinical decision-making.
Clinical applications include screening for anemia, monitoring hemoglobin in surgical patients, evaluating transfusion requirements, and tracking chronic conditions such as kidney disease. Rapid availability of results allows timely intervention, improving patient safety and care efficiency.
Safety and reliability are crucial. Devices should be regularly calibrated, cleaned, and used according to manufacturer guidelines. Accurate sample collection and proper handling minimize errors and…
