What is the purpose of making a standard graph for hemoglobin determinatiom?

The purpose of creating a standard graph for hemoglobin determination is to establish a reliable reference that correlates the absorbance readings from a spectrophotometer to known concentrations of hemoglobin. This standard curve allows for accurate quantification of hemoglobin levels in patient samples by comparing their absorbance values to the established curve. It ensures consistency, precision, and reproducibility in hemoglobin measurements across different analyses. Additionally, it helps to identify any deviations or anomalies in hemoglobin levels, aiding in clinical diagnosis and monitoring.
