What is HPLC blood test?

HPLC (High-Performance Liquid Chromatography) is a laboratory technique used to separate, identify, and quantify different components in a sample. In the context of a blood test, HPLC can be used to analyze and identify various forms of hemoglobin, such as normal hemoglobin (HbA) and abnormal hemoglobin variants (e.g., HbS in sickle cell disease). HPLC is a reliable method for detecting and quantifying different types of hemoglobin present in a blood sample, providing valuable information for diagnosing and monitoring certain blood disorders.
